Dear Rob,
We suspect your sighting was in Butler, Pennsylvania, not BuTyler.  According to BugGuide data, the Tiger Bee Fly ranges over most of eastern North America, including BuTyler, Pennsylvania.

Your letter to the bugman:  Hi Bugman,
This large fly (about an inch long) has been hanging around my deck for a few weeks.  It has an unusual habit of repeatedly darting at the railing when it hovers near the wood.  I am usually able to identify insects on-line, but have not had luck with this one.

Tiger Bee Fly

Dear Inconsistent naturalist,
This is a Tiger Bee Fly and we get numerous identification requests for them each summer.  The female Tiger Bee Fly lays her eggs in the nest of Carpenter Bees, which might be the reason this individual is hovering year your wooden railing.  We love your action image.

Tiger Bee Fly

Dear Tammy,
This is neither a butterfly nor a diurnal moth.  It is a Tiger Bee Fly, a harmless and very distinctive looking Fly.  See BugGuide for a comparison image.

Thank you so much for your time! I asked everyone around here if they knew what this interesting little creature that seems to have Zeus’s face on it’s back.
Best Regards,
Tammy

Bee Fly

Dear Eigo Creativity,
This is a Bee Fly in the family Bombyliidae and it looks very similar to our North American Tiger Bee Fly.  We believe your species is Anthrax anthrax which is pictured on Dave’s Garden.

Your letter to the bugman:  I found this interesting fella on a farm during December. I’d love to know what it is. I spotted it twice. Flies short distances and appeared to stay quite low to the ground.

Bee Fly

Dear Janine,
This is a wonderful image of a very striking looking Bee Fly in the family Bombyliidae, but alas, providing a species identification is proving to be difficult.  We did locate a matching image on Southern Africa Nature Photography and the blogger Selwyn Quan notes:  “The Bee flies (Family Bombyliidae) in South Africa have been very impressive. They are more than double the size of the Bee flies I usually spot in California, USA.  There is however a dearth of resources on the internet regarding identification of Bee flies of South Africa.”  We believe we eventually identified your individual as Bombomyia discoidea based on this iSpot posting and this iSpot posting.  Encyclopedia of Life has a nice image of a sexually dimorphic mating pair.

Tiger Bee Fly

Dear Sue,
This is the fourth image we are posting of Tiger Bee Flies, Xenox tigrinus, submitted to our site in the last week and a half.  It does not sting nor bite.  According to BugGuide:  “Larva is a parasitoid of Carpenter Bees, Xylocopa.”

Daniel –
Thanks so much! I do rent an apartment in a very old home in Southbridge, MA. The shed on the property is inundated with Carpenter Bees, so this makes total sense.
Best Regards,
Susan
