Wheel Bugs are Rolling Along

Wheel bug nymphs are completing their development and the adults of these large, unusual looking bugs are beginning to lurk among the leaves of trees and shrubs in Ohio in search of prey. Although caterpillars and sawfly larvae are favored table fare of this impressively large predator, they will not turn their beaks up at other arthropod meat morsels.

Botany in a Box

This past weekend my wife Laura came inside with a Botany in a Box she had collected and arranged from our backyard, a delightful mixture of flowers and miniature eggplants and melons, kousa dogwood fruits, crabapples, Korean maple fruits and more treasures. It is for her new 2nd grade class that started Monday.

 

  It reminded me of the simple joys of collecting and sharing these miniaturizations of horticultural and woodland nature. So, along with her welcome for her students, here are a few thoughts from an Akron Beacon Journal article I wrote eight years ago, with a box...

Garden Spider Orb Weavers

This is the time of the year when many species of spiders in Ohio begin to reach their maximum size as they fully mature. Two of our larger native spiders are the Black and Yellow Garden Spider and its similarly showy cousin, the Banded Garden Spider. Both belong to the orb weaver family (Araneidae), so named because of their flat, circular webs

Leaf-Footed Bugs

Leaf-footed bugs (family Coreidae) are rife with discrepancies. Their name is based on leaf-like expansions of their hind tibia, not their "feet;" however, many species lack the leaf-like feature. The family name Coreidae is derived from the Ancient Greek word for bedbug; however, bedbugs belong to a different family, Cimicidae. They are not called stink bugs (Family Pentatomidae), but some do stink.

Fall Webworm Update and More Red-Heads Found

Fall Webworm has two generations per season in Ohio. The "fall" in the webworm's common name is based on the appearance of second generation nests late in the season. First generation nests began to appear in southern Ohio in late May and second generation caterpillars are now on the scene. Localized fall webworm populations are high throughout the state with nests becoming more evident as they undergo late-season expansion.

Trumbull Trail Test For You

  Yesterday, I visited Lee Beers, the OSU Extension Agriculture and Natural Resource educator in Trumbull County, and as plant lovers (Lee is finishing his PhD on lowbush blueberry physiology and genetics), we had to take a walk. Adjacent to the OSU, Trumbull County office is county land and the Mosquito Lake State Park. So, in this 48-hour flash quiz, a prize awaits for the person with the most correct answers in that time to the plant and pest photo questions from our walk. If ties; the very first top score shall prevail.

Weed of the Week: Dayflowers Not So Common chatfield.1 Sat, 08/12/2017 - 08:19

In the ChatScape there is a lovely little flower, the Asiatic dayflower, Commelina communis, which has taken advantage of our travels this summer, invading any number of garden sites. It is well-known to move into “disturbed” sites, which may say something of this laissez-faire gardener, if not my wife. This herbaceous wanderer has quite a storied profile, from its two sky-blue petals subtended by one small white petal to the use of its blue pigments in Japanese dyes for woodcuts.

Going on an Egg Hunt - Gypsy Moth Style! stone.91 Sat, 08/12/2017 - 07:07

The gypsy moth (Lymantria dispar) is a non-native invasive species. This insect is currently in the egg mass stage, and will be in this stage until next spring when the caterpillars will hatch and begin feeding. Egg masses can help predict what population levels could be for the upcoming season. Now is the time to look for egg masses. Egg masses can be found almost anywhere. While we tend to look on trees, they can be found on homes, sheds, trailers, dog houses, bird houses, on firewood, on fences, yard art and signs. Egg masses can also be hidden under loose bark or in tree...

Interestingly, Curtis Young and Amy Stone in Northwest Ohio seldom see any evidence of locust leafminer beetle.  They have to travel east to at least Mansfield, Ohio before seeing the activities of this leafminer and it isn't because of a lack of black locust trees.

However, it's also why multiple colonies can quickly defoliate small trees.

Julie Crook and I spent a lovely afternoon yesterday “cruising” the Cincinnati Botanical Garden and zoo with Steve Foltz (Director of Horticulture) looking at their impressive plant displays and working with Steve on with some diagnostics. During our walk-about, Steve pointed out an “old friend” scurrying beneath a goldenrain tree (Koelreuteria paniculata; Soapberry Family, Sapindaceae): a Goldenrain Tree Bug (Jadera haematoloma).

Yellow Polka Dotted... Tomatoes??

I was called out to visit a high tunnel vegetable grower, who was concerned about what he was seeing on tomato leaves, which he hadn’t seen before on the plants.  He told me that spots had suddenly began to appear on his tomato plants, and that he really didn’t want to lose the plants or the huge crop of tomatoes that the plants had set.

Basswood Leaf Miner Damage Can Be Alarming

What begins as minor feeding injury on the leaves of basswood (Tilia spp.), can quickly become an attention grabber, especially if you are unfamiliar with the insect and the injury caused. The leaves appear to be torched and stand out among other trees in the area. The damage is obvious even as you are traveling on highways - at the recommended speeds of course

Backyard Flashers

I saw my first lighting beetles (Family Lampyridae) flashing in my backyard in southwest Ohio a little over a week ago. There were just a few; nothing to get too excited about. However, numbers have risen over the past few days to provide an impressive nighttime flashing display and I've gotten a few reports that the same is occurring in the central part of the state.

Bladdergalls

I came across an old friend in a southwest Ohio county park over the weekend: the wart like, irregularly shaped galls, known as "bladdergalls," adorning the upper leaf surfaces of a red maple. The galls are produced under the gene-manipulating direction of the Maple Bladdergall Mite, Vasates quadripedes (family Eriophyidae). The mite also produces bladdergalls on silver maple.

Look Closely for Lace Bugs

The characteristic leaf damage produced by Lace Bugs (order Hemiptera; family Tingidae) is becoming evident in southwest Ohio. Lace bugs are tiny insects with the adults measuring no more than 3/16" long. They are so-named because of the lace-like pattern of veins and membranes in their wings. The nymphs are even tinier and appear to be covered in small spikes.

Don't Touch This Weed!

Wild parsnip (Pastinaca sativa) plants are rising towards their full height and blooms are beginning to appear in southern Ohio. Landscape managers and gardeners should exercise extreme caution around this non-native invasive plant. Severe blistering can occur if chemicals (furanocoumarins (= furocoumarins)) in the plant juices come in contact with skin and the skin is then exposed to sunlight; specifically ultraviolet light. The effect is called phytophotodermatitis.

Calico Scale Crawl

Calico scale (Eulecanium cerasorum) eggs located beneath helmet-shaped females are hatching in southwest Ohio and the 1st instar nymphs (crawlers) are on the move. All nymphal stages are mobile, so all nymphs can be called "crawlers." The tiny, tannish-brown, oblong-shaped 1st instar crawlers are around 1/16" in length. They migrate to the undersides of leaves and position themselves along leaf veins where they insert their piercing-sucking mouthparts into phloem vessels to extract amino acids dissolved in the sugary plant sap.

Mulberry Whitefly "Pupae" Can Present an ID Challenge

Participants in Monday's Southwest Ohio BYGLive! Diagnostic Walk-About held at Stanley Rowe Arboretum observed final instar nymphs, called "pupae," of the Mulberry Whitefly (Tetraleurodes mori) on the undersides of holly leaves. The round, shiny black pupae are ringed in a white fringe and are commonly mistaken for a scale insect. Indeed, whiteflies are not "flies" (order Diptera); they belong to the same order (Hemiptera) as scale insects and share certain traits with both armored and soft scale insects.

Doggone Gorgeous Dogwoods!

Here in Northeast Ohio, it has been an incredible year for observing bloom of ornamental flowering trees.  I propose that both the marvelous color and length of bloom is due to the bursts of very warm temperatures (70’s), followed by days of cooler temperatures (50’s), with a day or two of rain mixed in to keep things fresh!  The warm temperatures caused the buds to push fast into full bloom; however, then the cool temps and the rains move in preserving not only the colors, but also prolonging the length of bloom appeal and persistence on the plants.

The crabapple plot, called Crablandia in Secrest Arboretum, is located in Wooster, Ohio and will be in full bloom and full splendor, in the next couple of days.  With the onset of multiple periods of unseasonably warm weather, the typical bloom emergence time is about 2 weeks ahead of schedule.  The incredible display of crabapple flowers has traditionally been one of the most popular times to stroll through the Arboretum and experience the amazing fragrance, accompanied by marvelous views of flower petals.

Rusty Junipers

Junipers in southwest Ohio are being garnished with tangerine tentacles and orange goo; the calling cards of rust fungi. The three fungi producing the colorful displays belong to the genus Gymnosporangium and each must alternate between a member of the plant genus Juniperus and members of the rose family (Rosaceae) in order to complete their life cycle.

Wilting Buckeyes

Wilting buckeyes may sound like an Ann Arbor dream, but I'm not talking about our beloved Silver Bullets. I'm referring to the symptoms caused by the Buckeye Petiole Borer (Proteoteras aesculana) on its namesake host.

Calico Scale is Puffing-Up and Pumping Honeydew

Overwintered calico scale (Eulecanium cerasorum) females are now "puffing-up" and pumping out impressive quantities of clear, sugary honeydew in southwest Ohio. The appearance of the globular, helmet-shaped females coupled with complaints of trees oozing sticky goo makes this life-stage important for detecting new infestations. All other life-stages are much less obvious.

Sneaky Common Chickweed is Going to Seed

Common Chickweed (Stellaria media) is a European winter annual that is now found world-wide. Winter annuals are sneaky weeds. They produce seeds in the spring then plants fade away prior to the summer season; out of sight, out of mind. The seeds dodge spring applied preemergent herbicide bullets because they do not germinate until the fall. The resulting plants grow below our radar throughout the fall, winter, and early spring when we pay little attention to what's going on in our lawns and landscapes.

Focus on Poison Hemlock Control

Poison Hemlock (Conium maculatum) is one of the deadliest plants in North America. This non-native invasive was imported as an ornamental in the late 1800s from Europe, West Asia, and North Africa. The plant contains highly toxic piperidine alkaloid compounds, including coniine and gamma-coniceine, which cause respiratory failure and death in mammals.

Tigers are Prowling Ohio Woodlands

My good friend Brad Bonham told me about a conversation she had with a landscaper over the weekend who declared they were seeing Emerald Ash Borer (Agrilus planipennis) (EAB) beetles mating in a woodland in southwest Ohio. Of course, as she noted, it's way too early for EAB adults to be on the wing; full bloom of black locust (Robinia pseudoacacia) is a good phenological indicator for EAB adult emergence.

Not Too Early For Ticks: Dog Tick

It's never too early for tick awareness.

Today, at the Extension Office, a tick sample was brought in for identification.  It was an adult male dog tick, Dermacentor variabilis.  Ticks are blood-feeding parasites.  Three species are medically important in Ohio as a vector of several diseases affecting humans and pets to varying degrees.  The American Dog Tick, along with the deer tick (or black-legged tick) and the lone star tick.  Tick populations have been an increasing problem in Ohio.

Eastern Tent Caterpillar Update

Eastern Tent Caterpillars (ETC) (Malacosoma americanum) caterpillars are accomplished and prolific tent-makers producing highly visible silk nests in the forks of branches. The nests are now large enough to be easily seen in Greater Cincinnati. However, at this point in the season, it appears that populations are highly localized and not widespread.

NW Ohio Anticipating Egg Hatch of Gypsy Moth

Conversations among family and friends this week could include dying, hiding and finding "eggs." It is Easter you know. 

 

The eggs that we are talking about in this BYGL Alert are those of the gypsy moth (Lymantria dispar).  After spending about nine months in the egg mass stage, warmer temperatures are triggering the hatch of the caterpillars in Ohio.  These tan almost felt-like in appearance masses that can be laid anywhere will soon be bursting with 1st instar caterpillars. 

While we are eagerly awaiting the first hatch in NW Ohio,...

Spring Lawn Seeding

 

This Turf-Tip was provided Joe Rimelspach and Todd Hicks with OSU – Plant Pathology and Turfgrass Program.

 

Of the four seasons, this is the “third best time” to seed a lawn. The best is autumn, then winter, followed by spring and the least desirable time is summer. The main challenge with the spring seeding is the large number of weeds (both grassy weeds and broadleaf weeds) that can come up with the grass seed. Seed as early as possible in the spring so new plant can develop a root system before summer heat and dry conditions...

Sawfly Leafminers Fly

I found Elm Leafminer Sawfly (Fenusa ulmi) adults flying around their namesake host yesterday in southwest Ohio. The emergence of this leafmining sawfly was predicted in my part of the state by accumulated GDD (219) and phenological indicators such as the full bloom of common chokecherry. This also means there is little doubt that Birch Leafminer Sawfly (F. pusilla) and Hawthorn Leafminer Sawfly (Profenusa canadensis) adults are on the wing.

Shrub of the Week: Buttonbush

  Native plants are all the rage in the plant world (apart from new hydrangea cultivars), and rightfully so―they are well adapted to our climate and zone, and serve as a host for a variety of insects, birds, and other wildlife. Indeed, when we plant a landscape we aren’t just making an area look nice. Rather, we are creating an ecosystem.

  A native plant that shines this time of year is Cephalanthus occidentalis, Buttonbush. This plant is commonly thought of only for its globular white flowers in summer. Yet this member of the Rubiaceae is attractive all season. Glossy...

Signs and Symptoms: A Tale of Two Tar Spots

  As noted earlier (http://bygl.osu.edu/node/525) there are two common tar spots of maple seen in Ohio.  One, that occurs commonly on silver and red maple results in dense, tarry spots caused by the fungus, Rhytisma acerinum. A second tar spot disease is typically found on Norway maple, with multiple tiny tarry spots that eventually coalesce into a larger spot, not quite as “tarry” but nonetheless black in color, caused by the fungus  Rhytisma punctatum.

Perennial of the Week: New England Aster

New England aster (Symphyotrichumnovae-angliae) is an excellent plant for the fall garden.  In addition to providing color in the landscape, it also is a late-season source of pollen for bees and other pollinators.  New England aster is native to much of the Eastern US and its purple daisy-like flowers can be seen in fields in bloom now.  It blooms from late summer through October. This plant prefers moist, rich soils but will tolerate clay soils, and some drought once established.  New England aster grows well in a sunny location but can also succeed in partial shade.  This plant...

Planting/Transplanting Perennials in Early Fall Requires a Little Extra TLC

The recommended time for planting or transplanting perennials is late August or early September.  This gives adequate time for roots to establish before winter comes.  However, like most gardeners, I don't usually think about it in late August and besides, this year was too hot to take on this task anyways.

{This Shrub of the Week article and its photos are from Paul Snyder of OSU's Secrest Arboretum at the Ohio Agricultural Research and Development Center in Wooster.}

  Have you ever had someone come to you looking for a particular plant, and then begin listing all the characteristics they are looking for? “It needs to be dwarf, have lots of flowers all summer, not be messy, and it can’t have thorns…” We have all been there, and we have all thought “With all those requirements you can’t really grow anything but perhaps poison ivy.”

Tree of the Week: Three-Flowered Maple

  The three-flowered maple continues to grow and thrive in my backyard and the more I see it planted at the Secrest Arboretum in Wooster, at the High Line Park in New York City, and elsewhere, the more I enjoy this tree. This Asian maple will become a small to medium-sized  tree (20-25 feet). Like its cousin paperbark maple, it has exfoliating bark but the bark is not as papery or with the cinnamon color of Acer griseum.

Pear Rust Revisited

  While walking in German Village in Columbus with ONLA’s Frits Risor last week we revisited the Callery pears with rust disease noted earlier this season (http://bygl.osu.edu/node/342). I wanted to see if the rust was isolated to the two trees heavily affected in June. As earlier, the two trees in question were speckled with bright orange lesions on the upper leaf surfaces, but I suspected that by now the rust fungus would have undergone sexual reproduction in the leaves with aecial spore pustules developing  on the lower leaf surfaces as would be seen with the cedar-apple rust fungus (...

Smorgas-gourd

  “I am ignorant of almost everything” is a favorite saying of mine, and truth be told it is an obvious truth for us all. It is what makes us so lucky to be plant lovers, since we are reminded with the new personal and universal discoveries of Nature every single day.  Know-it-alls need not apply for attendance at Nature’s banquets – though they might learn the most.  One of my recent revelations of a horticultural bent was about – gourds.  I have seen them, and have a vague sense that they are cucurbits, that is that they are in the Cucurbitaceae, the family that also includes...

Red-Spotted Purple

Look closely at woodland edges and you may see a flicker of iridescent blues accented with splashes of red; the calling card of a red-spotted purple butterfly (Limenitis arthemis astyanax).  The red-spotted purple is so named because of its overall purple hue and for the red to orangish-red spots on the underside of the wings.

Tar Spots of Maple

  Tar spots of maple, caused by species of the Rhytisma fungus, are prominent now, although mostly not as severe as in wetter summers. There are two different tar spot diseases of maple, one affecting silver and red maples, caused by Rhytisma acerinum, resulting in dense, tarry spots that truly reflect the “tar” spot name (first picture below).

Yes, We Have The Bananas

  I have marveled this summer about the impact of modern petunias in hanging baskets, planters, and planting beds in communities in Ohio and elsewhere. When I talk to landscapers such as Gene Pouly in Orrville about these petunias, they agree that petunias are indeed a boon to these sites, but they almost always add that there can be so much more to urban plantings. So, here is one of Gene’s planters, with the range of additional plants he uses outside Smith Dairy in Orrville, Ohio.

Slime Mold Sighting

  While walking about the other day I came upon a scene of serial sliming. A slime mold, probably a species of Mucilaga, was colonizing mulch under a maple tree. It was also colonizing a fallen maple leaf. It was also colonizing turfgrass plants next to the mulched area. This cohort of the colonized should tell us something: this slime mold is not very particular. It is not a parasite of this maple leaf or the turfgrass, but is just feeding on microbes in the decayed organic matter.  So no harm, no foul, relative to the need for controls. Just rake it or wash it off if it offends...

What is the Threat from Stinging Caterpillars?

The vast majority of lepidopteron (moths and butterflies) caterpillars, even many with hairs, do not present a threat.  However, there are some with hairs that are modified for defense.  These are collectively called urticating hairs from the Latin urtica meaning "nettle."  Indeed, the hairs on stinging nettle (Urtica dioica), which are called trichomes; provide a good model for the venom injecting mechanism used by some of the more serious urticating hairs found on caterpillars.

Beneficial of the Week: THe Dull Roar Effect

  The importance of beneficial insects and mites is often missed.  Until they are missed. We learned this years ago when “cover sprays” that included multiple pesticides in a “cocktail” were used repeatedly in hopes of controlling a range of pests, but had the unintended consequence of reducing or eliminating beneficial insect, mite, and spider species. 

Without these beneficials, we created monsters such as spider mite infestations on burningbush euonymus, that were much worse when cover sprays reduced beneficials.  We lost the “dull roar” effect of these beneficials that, while...

Beneficial Insects: Wool Carder Bees

Wool carder bees in the genus Anthidium are a beneficial pollinator that may be less familiar to pollinator-promoters than honeybees or bumblebees, but they are well-worth knowing!

 

This little bee is full of determination.  Female wool carder bees collect wooly material to line their nests.  To do this, she uses her mandibles to scrape fuzzy trichomes from pubescent leaves, especially lambs ear.  This scraping motion is reminiscent of a time when wool would be combed or "carded" to straighten the fibers.  While she toils away collecting soft, fuzzy things for her...

Rattlesnake Master is full of surprises.  It looks like it belongs in a desert, but it is actually a native prairie plant that grows well in the midwest.  While its basal foliage resembles that of a yucca (lily family), it is actually a member of the carrot family, Apiaceae.  It's flowers are a pollinator dream and its height adds something unique to the garden.

Annual of the Week: Euphorbia 'Diamond Frost'

Euphorbia is a genus in the family Euphorbiaceae; however, not all Euphorbia are equal.  Sometimes, the genes that support a plants demotion to weed status such as the ability to thrive in high heat and drought may be coaxed through hybridization to produce well-behaved, highly prized landscape plants.  Such is the case with Euphorbia 'Diamond Frost'.  This is a very tough plant that not only survives the dog-days of summer; but thrives!  All the while, the naturally mounded plants continue to be topped with clouds of delicate white flowers.

Weekly Weed: Spurge

Two types of spurge belonging to the genus, Euphorbia (family Euphorbiaceae), may become a problem at this time of the year in landscapes and turfgrass.  These are prostrate spurge (E. prostrata) and spotted spurge (E. maculata).  Both are summer annuals meaning that they develop throughout the growing season and produce seeds in late summer to early fall.  Both may flourish by lack of competition presented by poorly maintained or drought stressed turfgrass, or by the lack of weed suppression through poor mulching practices in landscapes.
