Anyone seen these beetles before? They are so bizarre! I’m glad I didn’t touch them. After identifying them on iNaturalist.org I discovered they have a very interesting life cycle associated with bees. They are called oil or blister beetles because they secrete an oily substance when threatened and can cause severe burns that are slow to heal. They are native to New Hampshire so nothing to be alarmed about, just don’t touch!
After some more research, these little beetles pack some potentially deadly chemicals. Be careful with pets, horses, and livestock. They can be found in hay / alfalfa.
