House Fly Pupal Parasitoid
A minute parasitoid wasp that develops inside house fly and stable fly pupae. It is sold commercially for biological fly management.
Did You Know?
Each female destroys about 50 fly pupae in her lifetime through a combination of parasitism and host-feeding.
Pale-Footed Birch Sawfly
A tiny black sawfly whose larvae create distinctive blotch mines within birch leaves. Mined leaves develop brown, papery patches.
Did You Know?
Heavy infestations can cause over 80 percent of birch leaves to become mined, giving trees a scorched appearance by late summer.
