Entomology (Study of Bugs)/Insect ID


I found this in our house.   It appears to be a type of Robber Fly but the large ( I guess ) proboscis is different than any thing I can find.   Can you identify.  Are they of a type that can sting.


Dear Mike - This is indeed a robber fly (Diptera: Asilidae); it appears to be in the genus Mallophora, likely Mallophora leschenaulti, commonly known as the Belzebul bee-eater, or the black bee killer - see http://tinyurl.com/q4g3v8p for images. They cannot sting, but one this size certainly could deliver a painful 'stab' with its proboscis if handled carelessly.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
