Along Came a Spider

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

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

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?

Chestnut Sawfly Found on Hickory

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

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.

Redbud Leaffolder Trekking Through Generations

Last season, the unusual leaf symptoms caused by the Redbud Leaffolder on its namesake host were observed throughout Ohio. Questions regarding leaves turning brown after being folded over or "glued" together continued to come into Extension offices throughout September. This could be a repeat season based on what I've seen so far.

Bagworms in the Bag

This has been an active season for Common Bagworms in Ohio with heavy localized populations observed in many areas of the state. Thankfully, the damage caused by these caterpillars wrapped in silk bags festooned with host plant debris is drawing to a close. A high percentage of bagworms in Ohio have now tied their bags to anchorage points and closed their bags' openings in preparation for pupation.

Anltions are the Pits

I was thrilled to come across the conical pits of Antlions yesterday; the handiwork of one of my favorite insects. I had become concerned that above average rainfall this season had drowned-out a robust year for these fascinating predators. However, the localized population in the home landscaping I visited appeared to be very healthy with pits in several locations.
