This bug is my friend
Hi Bugman,
We haven’t noticed creatures like these in the Central Valley of California until the last year or so. It’s possible that they’ve been here all along but I’m positive not in my back yard. What is particularly striking about this bug is it’s tendancy to hunt and kill Paper Wasps that lurk in my lawn and land on my pool. I really like this bug. I would like to know more about this one.
Thanks!
Friend Of The Wasp Hunters

Dear Friend,
This is a Robber Fly in the genus Diogmites, known as the Hanging Thieves. They are skilled fliers and hunters as your observations have proven.

bee like creature frightens dog
Hi!
Yesterday, ur dog Ellie alerted us to this bee-like creature in our backyard. It was frightening enough to throw her into a barking fit. Was she wise in warning us, or is this big guy harmless? (He/she is around 2 inches long..that is the bug not the dog.)
Thank you!

Hi Amy,
This is actually a Robber Fly in the Family Asilidae and it preys on bees. It is harmless to you and your dog, but if you try to pick it up, it will probably bite.

We had this flying around our work and finally killed it. What in the world is it?

Poor Dead Robber Fly. This is a beneficial insect that often kills and eats other pestiferous flies.

Is it a bee?
I found this insect late in the evening on my porch. I live north of San Antonio, Texas. It is about an 1 – 1 1/4 inch (body length). It is black with one spot of yellow on its thorax and yellow between and below each eye. The wings are brown. All the legs are furry and the hind legs have furry patches. It looks like a very large bee, but in trying to identify this insect the only thing that even remotely resembles it, is the carpenter bee, but the markings are no where near similar. Could you please help me identify this insect. Thank you!!!!

Hi Jamie,
We located your Robber Fly, one of the Bee Hunters, on BugGuide. It is the Southern Bee Killer, Mallophora orcina. Adults feed on honey bees which the descend upon rapidly while the bee is unsuspecting. They sieze the bee by the thorax so the stinger cannot be used. Nice photo.

a couple of photos and a moth ID
Hello
I wanted to let you know I love the site, and have used it for many identification forays since we moved out to the country here in south central Kansas. I also wanted send you to the url for three of my recent photos. (they are larger than I like to send through E-mail) One is of a mating pair of robber flies, it was interesting to watch as the male will vibrate his wings while wiggling the females head with his front legs. One is a photo of a green moth I found on the front deck this last night and I would appreciate any help with the ID you could give me. The last if of a green grasshopper. I do not know the species, but considering the number of them again this year, the chickens will be getting quite fat.
Thanks again,
William Tong

Hi William,
Thank you so much for the great letter and photos. We are also very happy that you have used the site in the past. Quite frankly, we are getting a little tired of responding to desperate housewives with pantry beetles. Your green moth is a Virginia Creeper Sphinx, Darapsa myron. If you go to this USGS site, you might find it is not yet reported in your county. Perhaps you could report the siting. We are thrilled to have your Mating Robber Fly image for our brand new Love Among the Bugs page. Your grasshopper is immature and we do not recognize it.
