Hi Bugman,
Another query for you. This one I’m fairly sure is a fly, at least. I looked through the fly pages, but couldn’t find anything that looked similar.
Photo was taken 5/26/13 in Swallow Falls State Park in western Maryland, in a forested area about 100 yards away from the river. Subject was about the size of a regular house fly. Apologies for the lack of detail, picture taken with iphone.

Snipe Fly

Snipe Fly

Dear long time reader,
We believe this is a Snipe Fly.  You can compare your image to the Common Snipe Fly,
Rhagio mystaceus, photos on BugGuide.  There isn’t much species information posted, but the data page shows most sightings in May and June.  The family page on BugGuide states:  “Both adults and larvae are predaceous on a variety of small insects.”

So there are these flies in the back yard and we can’t figure out what they are. They look a bit like deer flies, but have this really bright yellow gold furry thorax. Then we found two engaged in — um — adult activities and it looks like the males and females have different coloring. They are about 3/4 inch long. Any idea what kind of flies these are? Thanks!

Mating Golden Backed Snipe Flies

Hi Jeff,
Your photograph is of mating Golden Backed Snipe Flies,
Chrysopilus thoracicus, and each spring we get a few identification requests and they are often of mating pairs.  According to BugGuide:  “Life Cycle Details unknown. This fly is observed in early to mid-spring perched quietly on low vegetation in deciduous woodlands.”

Yesterday I saw what I believe to be a fly in the shade garden. It had one bright yellow spot on it.

Fly-like insect with black lacy wings&gold head or throat

I have a photo of 2 insects copulating (at least ( believe that’s what they were doing) in the grass at Crooked Creek Lake/Dam/Park in Armstrong County in western Pennsylvania. I cannot find them in 2 insect books I have and have posted the photo on an About.com Insect forum. I have watched dragonflies and damselflies, and other insects while birding but have never seen this particular insect.

Mating Golden Backed Snipe Flies

Dear birder/nature lover,
Despite the blurriness of your image, these are unmistakably Golden Backed Snipe Flies,
Chrysopilus thoracicus, and they are in fact “In Flagrante Delicto”.  They were our Bug of the Month in June 2009.  They fly in late spring.

Thank you, thank you, Daniel (Bugman extraordinaire).  I have become almost as interested in insects as I was in birds and critters.  I appreciate your ability to identify the flies in my poor “but idable” photo.  I have photos of other insects I was able to id such as the 6-spotted Tiger Beetle some people misrepresent as the deadly Ash Borer and once while birding up near Punxatawney, PA on the Shadow Mahoning Trail a few of us were awed while watching a Giant Ichneumon Wasp fly around us (looking for a log to lay her eggs on no doubt) and none of us had a camera!!!

Is this a horse Fly?

This bug was flittering with some northern cloudywing butterflys. they were chasing it away from the flowers. I thought it was a small butterfly but looking at the pictures later I decided it might be a Hoarse Fly but can’t find one with the bright yellow eyes. I live in Northern North Carolina. It was sighted on May 16 in the morning in my rural flower garden near a stream, woods and a meadow.

Golden Backed Snipe Fly

Dear J,
This is a Golden Backed Snipe Fly,
Chrysopilus thoracicus, and each spring, we receive several new images for our archive.  According to BugGuide:  “Adults are alleged to be predatory on other insects, but they may feed little (observations by BugGuide members).”  Additionally, bugGuide indicates that the details of the life cycle are unknown.

Horse Fly-esque?
May 30, 2010
I saw this thing back in our woods this morning crawling in the dirt. I went back in the afternoon with a camera and saw it siiting on this leaf. Got one photo before it flew. Searched and liken it to a horsefly, but have not seen any photos with the same color patterns. So, horse fly?
