What are these bugs
Please help ID. The green hairy caterpillar with black spikes was crawling on a log my grandson was target shooting. Photo taken late Sept/early Oct in Brown County, OH (Southwestern Ohio farmland). Green caterpillar walking on a board under a green ash tree on the farm 9-26. How do I know if you have ID’d this photos when I go to your website? Thanks.

Hi Mary Jo,
This is some type of Dagger Moth. We try to write directly to people and we post the best and most interesting letters and photos.

I have finally ID’d the green caterpillar with black spikes. In Caterpillars of Eastern North America by David L. Wagner, pg. 337, Cottonwood Dagger Moth, Acronicta lepusculina, Noctuidae. Yeah!
