I just took this picture of a bug on my balcony. I have never seen anything like it. It has six legs, kind of spiderish looking, but has wings, big eyes, and a black ”nose” or whatever you call it.
This is a predatory Robber Fly in the genus Diogmites, a group commonly called Hanging Thieves because they hang from a single leg while feeding. We have gotten numerous identification requests for Hanging Thieves in the past week.
Thanks for your quick reply! After reading up about the Robber Fly, it makes sense. We have a wasp problem, and the Robber Fly preys on them.
