Not a question, just sending for your info, as I couldn’t find a sighting that wasn’t in a southern state. I wrote you before I figured out what he was. Once I had, it did it was from southern states, and I’m in Pittsburgh, PA. I’ve lived here 8 years and never saw him until this spring, and since then he visited me every day. Today he was on my hand and other areas repeatedly, and for long periods. Glad I knew by then he wasn’t a very large hornet!

Yellow Jacket Hover Fly

Yellow Jacket Hover Fly

Hi Michelle,
Thanks for sending us your fun photo of a Yellow Jacket Hover Fly,
Milesia virginiensis.  Though most of our submissions are from the south, BugGuide lists the range as extending even further north than Pittsburgh.  We love the common name Good News Bee which you can read about on Beautiful Wildlife Garden.

Dear Josh,
Your photo isn’t that sharp, but based on this image from BugGuide, we believe this is a Fruit Fly,
Eurosta comma.

Hi Bugman,
I photographed a rather large two winged fly on my Butterfly Bush in Flagstaff Az.
This is the high desert, 7, 000 feet above sea level.
Low humidity, day time highs around 70,
50 at night.
We get snow in the winter months.
The abdomen is bright orange in color and rather stunning.
They have large fly eyes unlike bees.
Thanks,
R.A in Flagstaff

Tachinid Fly

Tachinid Fly

Dear R.A.,
This is a Tachinid Fly, an important family of parasitoid insects.  We posted a similar looking Tachinid Fly from the mountains of New Mexico that we featured as a Bug of the Month and tentatively identified as
Adejeania vexatrix.

I saw this fly outside on the table and ran to snap a picture. Is it a horse fly? It is about an inch long and entirely black.

Black Horse Fly

Black Horse Fly

Dear Jenny,
Yes this is a Horse Fly, and as you noted, it is black, so it makes sense that it is commonly called a Black Horse Fly, Tabanus atratus.  Your individual is a blood sucking female Black Horse Fly as evidenced by the space between her eyes.  The males of the species, like all Horse Flies, have much larger, more close-set eyes.  One can only speculate that such sexual dimorphism is due to mating and sexual reproduction.  We guess that male Horse Flies use their large eyes with 360 degree vision to spot females.

Can you please tell me what these are? They are the most annoying insects more annoying than flies or mosquitos!

Probably Lovebug

Probably Lovebug

Dear Thomas,
We wish you had a dorsal view of this insect, which we believe is a March Fly in the genus
Plecia, commonly called a Lovebug because mated pairs remain joined for an extended period of time.  They can get very common in the south when they form huge swarms.  According to BugGuide, they are also known as Honeymoon Flies.

Hi Thomas,
Thanks for sending a dorsal view.  We no longer believe this is a Lovebug, but we still believe it is some species of March Fly.

Not sure if this is a Southern or Florida Bee Killer, or just another type of Robber Fly. Super pretty, whatever it is.

Bee Killer

Bee Killer

Hi Sharon,
This is a stunning photo of a stunning Robber Fly.  We agree that it is a Bee Killer in the genus Mallophora, however we are not certain of the species.  Unlike the images of the Southern Bee Killer on BugGuide which have a black tipped abdomen, your individual has a yellow tip on the abdomen.  There is one Bee Killer also from Florida on BugGuide with the identical markings to your Bee Killer, however it is not identified to the species level.
