Participants at last week's Ohio Plant Diagnostic Workshop in Secrest Arboretum (OSU OARDC) viewed the round, pointed galls produced by the Oak Rough Bulletgall Wasp on its namesake host. They also observed – at a distance – the buzzing security detail protecting the immature gall wasps developing within the galls.

Reports of large numbers of "sweat bees" buzzing gardeners and other outdoor enthusiasts were common this past week. However, the vast majority of the hovering insects weren't bees; they were flies.

Small, sticky, snowy-white masses are appearing on the stems of redbuds in southern Ohio. They could easily be mistaken for soft scales, mealybugs, or insect egg masses. However, they are the "egg plugs" of a treehopper originally named the Two-Marked Treehopper.

This is the third BYGL Alert! this season that focuses on Fall Webworm (Hyphantria cunea). This Alert is in response to the numerous e-mail reports I've received of spectacularly large silk nests occurring in southwest Ohio. They are most likely the work of the red-headed fall webworm biotype.

August is the height of summer, and it is also the best time to spot the Asian longhorned beetle (ALB) as it starts to emerge from trees. The U.S. Department of Agriculture (USDA) is asking the public to take five minutes to step outside and report any signs of this invasive pest. Checking trees for the beetle will help residents protect their own trees and better direct USDA’s efforts to eradicate this beetle from the United States.

The vast majority of Common Bagworm caterpillars in southwest Ohio have initiated their annual "tie-off" in preparation for pupation. Bags are tightly closed and tied with silk to a twig or other anchorage point. Likewise, male bagworms in the northwest part of the state have tied-off; however, some female caterpillars are continuing to feed.

Damage by non-native Mimosa Webworms was a topic of discussion during today's BYGLive! Zoom Inservice. Curtis Young reported high localized populations in northwest Ohio and we both saw flaming honeylocusts last week in Knoxville, TN, as well as along I-75 in Kentucky as we each made our way back from the ISA International Conference.
