I just dunno about this one…
Good evening Mr. Bugman!
I am of course in need of your help in identifying a bee/wasp that I have encountered several times in my front yard. Let me stop and first say that I LOVE your site, and while I am pretty jumpy when it comes to most bugs, especially when they are on my person, (typical girl, I know) I have come to understand that they are here for a very good reason, thanks in part to you guys!! Ok I digress…back to my mystery bee/wasp. I live in Louisiana about 25 miles north of Shreveport on about 30 some odd acres, full of mostly pine and maple trees. In front of our house we have a nice sized tree stump, that we attempted to burn, (unsuccessfully). Everyday I go and come from work for about the past two months (or so) I have seen this nice sized insect hovering around this stump…basically protecting it, so it seems. It lands sometimes and pulsates it’s abdoman but I never see it doing anything else but chase off other insects. When I came home today I actually saw it mating with another one, and I ran inside for my camera, but by the time I came out it was by itself again. I checked every single bee, and wasp website I could find, (of course including yours), but got nowhere. Help me please Mr. Bugman! Thankfully yours,
The reason your search was fruitless is that this is not a bee nor a wasp. It is a Yellow Jacket Hover Fly, Milesia virginiensis. As its common name indicates, it is a fly that mimics a yellow jacket. You can locate more information on this Syrphid Fly on BugGuide.
