Bee Fly - Anthrax

Bee Fly - Anthrax
Canton, Norfolk County, Massachusetts, USA
August 3, 2005
Size: about 10mm
It was laying eggs inside the telephone pole. I couldn't find a good match from the pictures in the guide, but there were a few similar species, like the Tiger Bee Fly.

Moved from Anthracinae.

This is either Anthrax pluto or A. stellans. They both have this wing pattern with numerous large, isolated round spots which separates them from other north-eastern Anthrax species, but I would need a good lateral or ventral view to separate them.

Thanks Joel
I just looked back, and I didn't get any lateral shots. Maybe next time.

Moved from Tiger Bee Fly.

Xenox tigrinus, I think
This is now called Xenox tigrinus. Guide page for genus gives a summary (from of the creation of Xenox from other genera. Author of the genus is Neal Evenhuis. Guide page for species: Xenox tigrinus.

looks like
something other than X. tigrinus, I think; this one has separate spots on the wings, whereas all the images of tigrinus in the Guide have continuous black lines along the veins, as in Matthew's photo

my guess is something in Anthracinae (possibly Anthrax sp.) but I looked through all the current images and didn't find one close to this (and didn't find any images of other Xenox species on the web)

Anthrax sp. bee fly.
Pity it shares its name with the dreaded microbe! Gorgeous image.

not anymore
Actually, from what I've heard, this no longer belongs in the genus Anthrax. Apparently it's Xenox now. Sorry, I don't have a citation to go with that... Read recently that this species' larvae are parasitoids on larvae of Carpenter Bees. Have seen one other Bombyliid species here in NC also loitering suspiciously around Carpenter Bee nests.
