Magnolia Scale Update boggs.47 Mon, 10/09/2017 - 16:26
I first reported on Magnolia Scale (Neolecanium cornuparvum) this season in June when the maturing females were "puffing-up" and pumping out honeydew (see BYGL Alert, "Magnolia Scale is Pumping-Out Honeydew," June 16, 2017). My lengthy BYGL post included a description of the life-cycle for this "soft scale" as well as information on management options.

European Hornets Cause Concern boggs.47 Wed, 10/04/2017 - 10:26
At some point each season, I have come to expect receiving at least one phone call or e-mail message from a concerned Ohioan reporting they’ve found Giant Asian Hornets in our state. Although there have been no confirmed sightings of these hornets in North America, I never reject such reports out-of-hand.

Aphid Outbreak boggs.47 Tue, 10/03/2017 - 19:17
I got a phone call from a homeowner in southwest Ohio who said they had an aphid problem on willows. They described the situation as huge numbers of aphids dropping from large willows onto their home, driveway, and barn; sticky "sap" raining down on everything; and all manner of things acquiring a blackened patina.

Fall Home Invaders are Poised to Enter boggs.47 Sat, 09/30/2017 - 15:47
Now that fall is officially in the air, a number of insects and spiders are poised to make their way into Ohio homes. Indeed, with the recent spate of cool temperatures, I've gotten a few reports of gnat-like Hackberry Psyllids (Pachypsylla spp.) buzzing around homes and various spiders marching across floors.

Along Came a Spider boggs.47 Tue, 09/19/2017 - 14:09
Ohioans may be surprised by the large number of spiders living near at hand when heavy morning dews accentuate their gossamer creations. Their conspicuous web-work can be striking when highlighted by early morning sunlight along roadways.

White Masses on Stems of Wafer-Ash, Redbud, and Other Trees boggs.47 Wed, 09/13/2017 - 11:52
Participants in the S.W. Ohio BYGLive! Diagnostic Walk-About held this past Monday in the Boone County Arboretum (Union, KY) observed wafer-ash stems festooned with small, sticky, snowy-white masses. The masses could easily be mistaken for a soft scale, mealybug, or perhaps an insect egg mass. In fact, they are the "egg plugs" of the Two-Marked Treehopper (order Hemiptera; family Membracidae).

Bullet Galls and Bullet-Like Stingers boggs.47 Wed, 09/13/2017 - 00:07
Participants in last Friday's 84th Ohio Plant Diagnostic Workshop held in the OSU OARDC Secrest Arboretum braved experiencing bullet-like stings to view numerous bald-faced hornets buzzing Oak Bullet Galls. The galls were also drawing the attention of a few yellowjackets and other stinging insects as well as some flies and ants. Of course, the question on everyone's mind was why were these insects being drawn to the galls?

he late-season handiwork of the Basswood Leafroller (Pantographa limata, family Crambidae (Crambid Snout Moths)) clearly describes the unusual leaf-abodes created by this moth caterpillar. Individual translucent green caterpillars reside inside cigar-like nests created in a repeating three step process.

Chestnut Sawfly Found on Hickory boggs.47 Thu, 09/07/2017 - 14:18
Participants at last week's First Annual Tree and Plant Diagnostic Walkabout Workshop held in Lake Hope State Park in Vinton County, OH, came across a group of striking black-and-yellow striped sawfly larvae feeding on hickory. I had never see this sawfly before and after exhausting all of my usual routes for identifying tree pests, I followed the advice commonly given to me by seeking professional help.

Stinging Caterpillar Commentary boggs.47 Thu, 09/07/2017 - 14:14
I learned a valuable lesson during last week's First Annual Tree and Plant Diagnostic Walkabout Workshop held in the beautiful Lake Hope State Park in Vinton County, OH. If you want to find caterpillars, you should hike with Tom Macy, Forest Health Program Administer, with the Ohio Department of Natural Resources, Division of Forestry. Tom's cater-optic prowess is truly remarkable.
