Your letter to the bugman:  Can’t find anything like it in my bug books.
Have not found on any web searches. Is it a fly or a moth?

Horse Fly: Leucotabanus annulatus

Dear Farmer Bob,
This is definitely a fly and the large, close set eyes indicate a male.  We were nearly certain this is a Horse Fly but we cannot ever remember seeing a white Horse Fly.  Our web search quickly brought up a FlickR posting of
Leucotabanus annulatus. We then confirmed its identity on BugGuide and learned the preferred habitat is “places where there are trees and rotting wood.”  We are very excited as this is a new species for our site and it is a magnificent species.  As an aside, female Horse Flies suck the blood of warm blooded animals and they will bite humans if there is no other source of blood.  Males do not bite, do not feed on blood and pose no threat to humans.

Your letter to the bugman:  Hi bugman! Your website helped me identify what my friend called “demon bug from the pit” as a Hanging Thief or robber fly. I wanted to share some photos I was able to get with this chill little specimen

Hanging Thief

Dear Layla,
We cannot possibly answer and post every request we receive, and we respond to many more (though by no means all of them) than we are able to post.  While we have recently posted several new Hanging Thief images, your images are exceptional and a wonderful addition to our archives.

Your letter to the bugman:  We saw this winged insect on our bus today, we would love to know what it is! Have not seen before in our neighborhood. The insect was about 1” -1.25” in length. And it is hanging out on the bus still, going to Canarsie!

Hanging Thief

Dear B13 bus rider,
This is a Hanging Thief, a predatory Robber Fly in the genus
Diogmites. They are called Hanging Thieves because they often hang from one leg while feeding on prey.

Hanging Thief

Wow! Thank you so much for the ID! Very cool. My kids and I were coming up with all sorts of terrifying and fantastic possibilities, and this commuting insect now features prominently in our imaginary storytellings. Wonder where the Hanging Thief is now, and if it has found any prey aboard the bus?
Thanks again! We love your site!

Your letter to the bugman:  I saw this bug today, and I have never seen it before. It flew very strangely compared to other bees. Does it sting?

Yellowjacket Hover Fly

Dear Julia,
This is a Yellowjacket Hover Fly, also known as a Good News Bee.  Hover Flies neither sting nor bite, however, they do mimic the stinging Yellowjacket to discourage predators
.

Yellowjacket Hover Fly appearing dead

It is somewhat troubling to us that this harmless creature is alive in one image, and appears dead in the second.  It is our mission to educate the public about insects and other things that crawl, and since the Yellowjacket Hover Fly is harmless, we consider this to be an example of Unnecessary Carnage.

Your letter to the bugman:  Hi there bugman,
This extra-large fly was on my window and I want to know if I should be afraid or not.

Female Horse Fly

Dear Jessica,
This is a female Horse Fly in the genus
Tabanus, and we believe based on BugGuide images that it might be Tabanus abdominalis, or possibly Tabanus limbatinevris which is also pictured on BugGuide.  Female Horse Flies are blood suckers that feed off livestock wild animals, but they will bite humans if there is no other prey.
