Camp Canopy Goes Virtual - Check It Out!

What began in 1950 as a young sapling, Camp Canopy (formerly known as Ohio Forestry & Wildlife Conservation Camp) has grown into a mighty oak as one of the most popular summer camps among high schoolers in Ohio, hosting 10,000+ campers since its inception. Many students have taken what they learned during their summer(s) spent at Camp Canopy and have gone on to study natural resource disciplines at their post-secondary institutions. Others have simply learned a ton of cool stuff related to forestry and wildlife in Ohio. Either way, Camp Canopy’s legacy will live on in generations of...

"Concrete Mites" Are Out: Look Before You Sit!

So-called "concrete mites" are making their annual appearance in southwest Ohio. These tiny, fast-moving bright red mites scurry around on sunny surfaces such as on picnic tables, patios, sidewalks, concrete retaining walls, and on the outside walls of homes and buildings. They are called concrete mites owing to the locations where they tend to congregate.

Aphid Galls Rising on Elms

The leaves of native elms can look a bit bedraggled at this time of the year owing to the rise of pouch-like elm sack galls and the descriptively named elm cockscomb galls. Fortunately, neither of these aphid galls produce significant injury to the overall health of their elm tree host. Unfortunately, these odd-looking plant structures can spoil the aesthetics of their deep green elm leaf platforms.

Yeasty Beasties, Slim Flux, and Other Natural Wonders

I came across a colorful agglomeration of slimy growth on a cut stem of wild grape (Vitis spp.) during a recent walk in a local park. With a little imagination, the shimmering mass took the form of a strange sea monster with a dripping nose, perhaps because of our high pollen count. Of course, I had a little fun with enhancing the effect.

Friday, June 5 - Virtual Escape to the Forest - Forest Insects: Native and Non-Native

 

The OSU's Ohio Woodland Stewards Program in the School of Environment and Natural Resources (SENR) is offering online Friday's in the Forest during this pandemic.

 

Next Friday you can join OSU’s Amy Stone and Joe Boggs as we look at some native forest insects and some non-native forest insects.  Insects that create ‘tents’, insects that dance, along with insects that create galls and insects that suck sap – something for everyone.  The virtual session will be offered on Friday, June 5, from 10:00 am - 12:00 pm.

Nostoc commune: From "The Blob" to Crusty Black Stuff

Recent heavy rainfall across Ohio has been very beneficial to the cyanobacterium, Nostoc commune (NC). Of course, that's not the name that most Ohioans will use to refer to this ancient organism. E-mails and phone calls to horticulture professionals may describe it as rubbery yellowish-green or bluish-black growth rising from the soil; some may just describe it as "the blob."

Ant Wars

"Ant swarms" are most commonly associated with ants mating and the subsequent establishment of new colonies. However, non-native pavement ants (Tetramorium caespitum) may also swarm for a more nefarious purpose: to conduct full-blown, no-holds-barred ant wars.

Holey Elms

Holes can appear in the leaves of native, non-native, and hybrid elms at this time of the year owing to damage caused by the non-native elm flea weevil. This weevil was incorrectly identified as the European elm flea weevil for many years. However, the true identity was sorted out a few years ago.

Holey Oaks

What's making holes in newly expanding oak leaves in Ohio? The common name of the oak shothole leafminer (Japanagromyza viridula, syn. Agromyza viridula) clearly describes both the culprit and the damage they do to oaks. This small fly belongs to the family Agromyzidae; the leaf miner flies.

The Right Redbud For You

Eastern Redbud, Cercis canadensis, put on a show this spring! It did not matter where, the redbuds were simply outstanding. Most of the flowers on Cercis canadensis even survived the cold of May 8-11 with little or no injury. Perhaps it was the shelter-in-place order that made spring flowers seem especially brilliant this year, or maybe they really were better than usual. Whatever the case, I am not going to complain!

Woodland Wonders: Spring Ephemerals Sing the Blues

The spring ephemeral season is nearing its end in Northwest Ohio as the woodland trees and shrubs leaf out. Temperature largely dictates the pulse of when wildflowers bloom and fade on the forest floor. Our rather cool spring allowed dozens of white blossoms to linger for several weeks. These flowers are now mostly gone aside from a stray spring beauty here and there, replaced by a show of blue and purple blooms. Two warm, sunny days above 70°F pushed the fast-forward button on flowering last week.

These are the tail end of...

Woodland Wonders: A Tale of Two Vines

 

Vines are trailing plants that use stems, tendrils or adventitious roots to help them “climb” up surfaces like walls, bricks, stone, plants and trees to reach new heights.  The curious nature of two vining plants – Virginia creeper and poison ivy - came to light this past week. Both plants are native, herbaceous perennial vines with compound leaves commonly found throughout the woodlands of Ohio. Often, they grow near one another or even intertwined on the same tree. Can you tell these two plants apart?

Woolly Aphids on American Elm

Thanks to the sharp eyes of Dave Bienemann (Municipal Arborist/Utility Forester, City of Hamilton), I was able to take some nice pictures of the woolly apple aphid (Eriosoma lanigerum) and it's characteristic damage on its alternate host, American elm (Ulmus americana). This isn't the only woolly aphid that uses our native elm as an alternate host. The woolly elm aphid (E. americanum) is another historical American elm pest.

Marsh Marigold Madness

On one of our jaunts through the woods and parks in NE Ohio, my wife was thrilled to see glorious blooms of intense yellows created by Caltha palustris or Marsh Marigold (MM).  The genus name “Caltha” is derived from the Latin meaning “yellow flower” and the specific epithet “palustris” means marsh-loving.  Therefore, the Latin binomial for this plant literally means “yellow flower marsh-loving”!!  This North American native plant thrives in bogs, ditches, swamps, forested swamps, wet meadows, marshes, and stream margins from as far east as...

Japanese Maple Scale (JMS)

Scale management is difficult but an incorrect identification can make it impossible. This is sometimes the case with the exotic Japanese maple scale (JMS) (Lopholeucaspis japonica, family Diaspididae). It's relatively new to Ohio, its name is misleading, and it may be mistaken for other more familiar scales.

Heavy Maple Seed Production = Slow Leaf Development

Phone calls and e-mail messages to Extension offices from landowners concerned about the health of maples should soon be on the rise. That's because maples, especially silver (Acer saccharinum) and red maples (A. rubrum), in many regions of Ohio as well as Indiana and Kentucky are producing loads of winged seeds (samaras).

Invasive of the Week - Japanese Knotweed Popping Up

Often we take notice of invasive plants when they are most obvious - they are in bloom, have put on their yearly growth and are standing tall or maybe wide in some cases, and really can't be missed. But today, I wanted to share an early view of an invasive perennial, Japanese knotweed (Fallopia japonica). That review includes last year's left-overs, hollow stems standling leafless. No new growth will be initiated from these above stems and soon will be masked or hidden by this year's new growth.

Personal Protective Equipment Shortages for Pesticide Applicators

This spring pesticide applicators are likely to encounter a new challenge getting the personal protective equipment (PPE) required to make their pesticide applications. The emergency needs that first responders and medical care providers have for PPE in the COVID-19 battle have led to shortages of all types of PPE, even for types not typically worn by medical personnel. By the time that PPE become more readily available, it will likely be too late for many spring (or even summer) pesticide applications. What to do?

Deciduous trees and shrubs can produce a dependable flower show, but the flower buds that create the flowers need to be kept in consideration to prevent damage.

Additional BYGL Alerts will follow as we track the progression of spring, and ultimately summer, in the buckeye state.

The Rise of Poison Hemlock

Poison hemlock is a non-native biennial weed that spends its first year as a low-growing basal rosette; the stage that is currently very apparent. Targeting this stage for control will eliminate the first-year rosettes and prevent the development of the towering flowering stage.

A Super Time to Scout for Bagworm! (Cone in the middle)

With the Big (football) Game approaching this week, we have a Big opportunity to look for some potential Big problems with our evergreens. When a tree just doesn’t ‘look right’ from a distance, you can begin to assume that something isn’t right with the tree. Winter is a great time to make some of those observations. Bagworm may be the reason.

Remontant Recurrence Again

Plant blooms are the typical focus as we progress through a growing season, but people become panicky when plants don’t perform how they normally do.  It’s the time of year that concerned citizens call in wondering whether or not their magnolias or rhododendrons are signaling they are going to die.  When asked why they think that the plants are going to die, the response is always the same, “because they are blooming again and they already bloomed this year!”

The caterpillar feeding frenzy has ended for the year and adult activity is being observed in NW Ohio. The male moths have taken flight in their zig-zag pattern in hopes of finding a mate. The female moths are white and a bit larger in size, and typically don't move far distances from the pupal casing that they emerged from. She gives off a pheromone to alert close by males of her location. After a visit from the male moth, she will begin laying eggs. The mass of eggs laid now, will remain in that stage until the following spring.

Basswood Lace Bug on Silver Linden: Harbingers of the Lace Bug Season

I've long admired silver linden with its dark green leaves accentuated by silver undersides. This tough tree is able to handle many of the urban slings and arrows that send less hardy trees to wood chippers. However, this eastern European native seems to be having a growing challenge with our native basswood lace bugs.

Scuzzy Looking Oaks

Holes and blotch-type leafmines produced by the oak shothole leafminer coupled with necrotic tissue caused by oak anthracnose are combining to make some oaks in southwest Ohio look pretty scuzzy. The bad news is nothing can be done now to reverse the damage. The good news is that neither of these occasional springtime afflictions has a history of causing significant harm to the overall health of their oak hosts.

Watch Out Four-Line Plant Bug - She Means Business (For Real This Time!)

In 2018, around this same time period, I wrote a BYGL Alert about the damage in my garden caused by the four-lined plant bug (Poecilocapus lineatus). I was a bit upset because of the amount of damage to a wide variety of plants. I SAID I was going to take action but of course, I never got around to it. Well, that's about to change this year!

Look Before You Sit on Concrete

We're seeing large numbers of tiny, fast-moving bright red mites scurrying around on sunny surfaces such as on picnic tables, patios, sidewalks, concrete retaining walls, and on the outside walls of homes and buildings in southern Ohio. These nuisance mites belong to the genus Balaustium (family Erythraeidae) and are sometimes called "concrete mites" owing to locations where they tend to congregate.

Bedraggled Elms: Galling Conditions

The leaves of native elms can look a bit bedraggled at this time of the year owing to rise of pouch-like elm sack galls and the descriptively named elm cockscomb galls. Fortunately, neither of these aphid galls produce significant injury to the overall health of their elm tree host. Unfortunately, these odd looking plant structures can spoil the aesthetics of their deep green elm leaf platforms.

Bedraggled Elms: Elm Leafminer Sawfly

The leaves of native elms, non-natives, and hybrids can look a bit bedraggled at this time of the year owing to the leafmining activity of the elm leafminer sawfly. Fortunately, leafmining by the sawfly larvae has drawn to a close for the season, so the damage you see now will be the most damage that you'll see this season. Unfortunately, sawfly development has moved past effective control options meaning that you'll have to live with the current damage.

Calico Scale Egg Hatch

Calico scale eggs located beneath helmet-shaped females are beginning to hatch in southwest Ohio. This life cycle event happens quickly; the small number of 1st instar nymphs that I spotted yesterday will soon become a horde. Unlike armored scales, all nymphal stages of this soft scale are mobile, so nymphs can be called "crawlers" throughout their development.

Picking Up Pawpaws.. Blooming

As I was in the throes of cutting and baling my overgrown lawn last week in Northeast Ohio, I was pleasantly surprised to see a profuse flower display on my Pawpaw (Asmina triloba) trees!  I can’t recall ever seeing so many buds and blooms on the tree, especially the numbers which were noted this season.  Now some may opine that the green, brown fuzz covered bud scales are the reason most people ignore and consequently, miss the real floral display, because the buds seem so uninspiring.

Bladdergall Enlightenment

My introduction to the wonderful world of plant galls began with observing vibrant red, wart-like galls, known as "bladdergalls," adorning the upper leaf surfaces of a silver maple tree. The galls consist entirely of plant tissue and are produced under the plant gene-manipulating direction of the Maple Bladdergall Mite (family Eriophyidae).

ODA Announces 2019 Gypsy Moth Open Houses

The gypsy moth is a non-native pest that feeds on leaves and needles of over 300 different trees in the buckeye state. The feeding injury occurs in the spring and early summer when populations are present. The early season feeding, when heavy, causes the plants to push new leaves that ultimately are the food-factories for the rest of the year. Healthy deciduous trees can usually recover as long as there isn't repeat defoliation year after year. Evergreens can die in a single season.

Blue-winged wasps are continuing to make low-level flights over lawns in southwest Ohio. As their common name implies, the wasps have dark blue wings. Their legs and thorax are also dark blue. However, their most distinguishing features are two light-yellow spots at the top of their orange-tipped abdomens.

A Non-Native, Native Lizard

If you're ever visiting Cincinnati during the dog days of summer, keep your eyes peeled for a fascinating non-native lizard scurrying over rock walls, darting across sidewalks, and lurking in landscaping. These lizards are intriguing because the story of how they got to Cincinnati and their ascent to equal treatment amongst native reptiles is almost unprecedented for reptiles in Ohio.

Redbud Leaffolder Damage

Participants at last week's Greater Cincinnati Diagnostic Walk-About were thrilled to view the unusual leaf symptoms caused by the Redbud Leaffolder on its namesake host. Or, maybe it was just me who was thrilled. Most of the leaf damage this season is produced by the current 3rd generation caterpillars.

Asian Longhorned Beetle (ALB) Cooperative Eradication Program in Ohio Scores Another "Win"

Asian Longhorned Beetle (ALB) is potentially the most devastating non-native pest to have ever arrived in North America. The beetle kills trees belonging to 12 genera in 9 plant families. This includes all native maples, a preferred host. Successful eradication is essential to avoiding a catastrophic loss of trees on a scale never before seen in the U.S.

Monarch Migration

The annual migration of monarch butterfly (Danaus plexippusis) has begun. It has to be an amazing adventure if you are the butterfly, or spectacular site if you are a person able to observe the migration in progress.

Beech Blight Aphids Shake Their Booty

I believe no other insect upstages Beech Bligh Aphids in entertainment value. During a visit to a Lake County, OH, park last Thursday, Jim Chatfield and I came across a cluster of these engaging aphids shaking their woolly derrieres in what appeared to be a synchronous samba. All we needed was "(Shake, Shake, Shake) Shake Your Booty" by KC and the Sunshine Band blaring in the background to complete the effect.

Thousand Cankers Disease (TCD) Update – Don't Rush to Cut Walnut Trees!

The long-term outlook for eastern black walnuts seemed dire when the Thousand Cankers Disease (TCD) complex was confirmed in Butler County, OH, in 2013. Thankfully, TCD has not followed the devastating trajectory we originally feared. It is not rolling through our native black walnuts à la emerald ash borer on native ash. The two situations are like apples-to-oranges.

No Asian Hornets in the U.S.

When you read or hear about "Asian hornets," you need to keep two things in mind. First, the "Asian" moniker has been commonly applied to at least three hornet species native to various Asian regions. The second thing to remember is that none of these hornets have been found living in the U.S.

Invasive Plant Species Alert - Japanese Stiltgrass

Japanese stiltgrass was not on my radar until a recent visit to a local park. It had piqued my interest because of the plants lushness beneath a full canopy of trees. My first thought was, what is this grass that could be a recommendation for shady sights? My excitement quickly waned because our hosts explained that the annual grass unfortunately, is an invasive species.

Eastern Filbert Blight on Hazelnut

Eastern filbert blight is a disease of filbert and hazelnut trees (Corylus spp.). It is caused by a native fungus. In a natural setting, filbert blight causes a relatively minor disease on native American hazelnut shrubs (Corylus americana) causing small cankers on the stems and branches. However, the disease is lethal to introduced and commercially important European hazelnut (Corylus avellana) in orchards.

Annual of the Week - Cotton

This interesting annual caught my attention earlier in the season, and it just kept getting better and better.  As the cotton plant grows, it can be quite the conversation piece. It can be planted in the ground or in containers. It prefers poor and dry soil conditions. The planting at Toledo Botanical Garden (TBG) is a mass planting in the Artist Village where the cotton will be harvested and utilized by local artists. The plants are approximately 4 feet tall.

Bagworms are Wrapping Up

Most of the Common Bagworms I looked at yesterday in southern Ohio and central Indiana had initiated their annual "tie-off" in preparation for pupation. Bags are tightly closed and tied with silk to a twig or other anchorage point. This means the damage caused by these caterpillars wrapped in silk bags festooned with host plant debris is drawing to a close.

Slime Mold on Turfgrass

Slime molds can be found on all types of turfgrasses – from cultivars chosen for lawns to weedy grasses that pop up in places were regular maintenance just isn’t regular. Slime molds are usually more noticeable following extended periods of leaf wetness. With recent rains experienced in NW Ohio, people have been asking "what is going on in my lawn?"

Fall Webworm Update

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. The first generation began to appear in southern Ohio in late May (see, "Spring, Summer, Fall Webworms," June 13, 2018) and second generation caterpillars are now on the scene.

Sneaky Stink Bugs

I'm seeing damage on ripening tomatoes in southwest Ohio caused by Brown Marmorated Stink Bug nymphs. I first saw damage from both the adults and nymphs on my own tomatoes in 2015. At that time, we didn't know which direction BMSB populations would take in the southwest part of the state.

Morning Dew Brings Gossamer Creations to Light

This is the time of the year in Ohio when female spiders of many web spinning species reach maturity. They become most evident when their gossamer creations are illuminated by early morning sunlight reflecting off a heavy dew. I was lucky to experience this magical but fleeting light effect during an early morning hike around my neighborhood a few days ago.

A Real Sweet Dilemma

I was asked to help a vegetable grower figure out what was going on with something wreaking havoc and eating his ripening sweet corn.  Typically, when someone mentions sweet corn and problems, the first demon that comes to mind are those little masked, sweet-toothed bandits, known as raccoons!   When I arrived out in the field, I was surprised to see the corn stalks standing tall in nice rows.  The masked marauders climb up the cornstalk to the get to the ripest, uppermost ear of corn; consequently, the corn stalks are most often snapped off or pushed over down to the...

A Blooming Bias

In the world of plants, most often our attention focuses on bloom color, size and timing of when blooms will make an impact in our landscape.  Blooms are nice as a moving focal point during the growing season, but people become a little upset when plants don’t do what they are supposed to and only when they are supposed to do it.  This is the time of year that concerned citizens call into the office wondering whether or not their magnolias or rhododendrons are going to die.  When asked why they think that the plants are going to die, the response is always the same, “...

Blister Beetles Wreaking Havoc on Tomatoes

I received two e-mails over the weekend from backyard gardeners in southwest Ohio with pictures showing Black Blister Beetles swarming over tomato plants. Black blister beetles as well as Margined Blister Beetles are the two most common species found in Ohio. Both beetles are capable of showing-up in large numbers to feed on the leaves and flowers of a wide range of perennials and annuals including vegetable plants.

Marestail (Horseweed)

Marestail, which is also known as "Canadian horseweed," or just "horseweed," has moved from field crops to become a plague in landscapes and nurseries. The main reason is that certain biotypes are resistant to glyphosate (e.g. Roundup) as well as a number of other agricultural herbicides. In fact, this native North America plant has become such a problem in Ohio it has been added to the state's noxious weeds list.

Monstrous Porcelain-Berry Barrage

I posted a BYGL Alert last October on Porcelain-Berry when the problem berries were fully ripened and available for widespread distribution by birds and other animals. I'm revisiting this ever-expanding non-native vine because its invasive arc in southwest Ohio is being compared by some horticultural professionals as possibly rivaling kudzu.

Embrace the Milkweed Menagerie

This is the time of the year when the menagerie of insects that feed on members of the dogbane family (Apocynaceae), including common milkweed, seem to arrive en masse … to the consternation of monarch lovers! Some aim to reserve milkweeds for monarchs. What about other native insects that feed on milkweeds; let them eat cake?
