Rose Chafer
5712 Hello, I live in Ottawa Ontario and these bugs are everywhere eating my plants especially my fruit tree leaves. They started to show up on the 15th of June, and they where around all summer until the end of August. They are around 3/8ths long and brown with black wings.
Like no. 5710, this appears to be a rose chafer (Macrodactylus subspinosus; Coleoptera: Scarabaeidae). Ed Saugstad, retired entomologist; Sinks Grove, WV.
