The bald-faced hornet isn’t actually a true hornet, but an aerial yellow jacket. It’s easy to identify since it’s Michigan’s only black and white yellow jacket.
It gets it’s name from the black and white marking on it’s face, thorax, and abdominal. They range in size from 12mm to 15mm, with queens being bigger ranging from 18mm to 20mm.
Despite their large size (bigger than yellow jackets), bald face hornets are less aggressive compared to yellow jackets. However, they are still able to sting multiple times because of their smooth stinger. Most stings from bald face hornets are a result of their nest being disturbed or threatened.
