Monday Nature Mystery

We are pleased to announce the winner of our last Monday Nature Mystery, Grant WestPlease email us your snail mail address and preference for a hat or tote bag to: [email protected]

Congratulations to Grant for correctly identifying the Hanging Thief. According to Insect Identification’s website, the Hanging Thief is a type of Robber Fly in the genus Diogmites. This carnivore eats other flying insects by hanging around until its prey flies by. It eats biting flies, dragonflies and other flying insects. This species makes a loud whirring noise as they fly because they beat their wings so quickly!

I’m a common butterfly but you might not recognize my ventral side! The ventral side is the underside of the wing that you see when a butterflies wings are closed.
