Tiny Bowlegged Wasp - Brachymeria podagrica - male

Tiny Bowlegged Wasp - Brachymeria podagrica - Male
Alexandria, Fairfax County, Virginia, USA
Size: ~3 mm
This was found January 17, 2010.

Over the past several weeks, I've found five of these in my house. They remind me of the tiny wasps that hatched out of a butterfly chrysalis I found last summer, but if they all hatched at once, I don't know what those I found several weeks later were surviving on. What are these?

Moved from Brachymeria.

The more I look at this and t
The more I look at this and the other pictures of known Brachymeria the more convinced I become that this is just a mellanic form of B. fonscolombei. When you look at the areas where the ivory spots should be you find a corresponding paler spot in the background color. The situation of being found indoors in "numbers" also supports this identification. Its the only species that I regularly find indoors, due to it's parasitism of carrion flies larvae.

And its a male.

Thank you
for the further examination and information!

If you found them indoors it may be a good idea to remove the date from the data field and keep it only on the text. Perhaps adults are not found normally outdoors this time of the year.
Neat little fellow and a lot of detail in this images.

Thanks -
suggestion taken. Sure do wish I knew where they came from! Still a mystery, but I haven't found another in a while now.

Moved from Chalcid Wasps.

This morning
I found #6 in my bathroom window and then #7 at my door glass. It's been at least five weeks since finding the first one. They are all fairly sluggish and stationary - I haven't found any actually flying around. I think I've found all of them at the windows.

they go straight to the windows to break free, disperse,...
...and find new hosts -- that's what you do if your lifestyle involves a [host] substrate routinely present in limited amounts scattered across the territory in unpredictable ways

I just found #8
YESTERDAY at my glass door. Now I REALLY wonder what their host is!

Hello to you, btw - I did get your message, but I've been without internet access for a lot of the last three weeks, or really busy. Meanwhile, I keep taking pictures... Got LOTS of bugs in the backlogs by now. Just need time to process and post! =) Taking a few minutes to do a bit today with all the fresh bugs I just found in FL. I hope you're well.

I'm really wondering
what their host was, that has them showing up across five weeks in my house.

I have let every one go outside, except the two from this morning - they're still in the capture cup.

Its probably something close
Its probably something close to Brachymeria fonscolombei. That species parasitizes maggots of carrion feeding flies. I've had them show up in homes due to dead rodent or bird carasses in the attic space.

I live in a basement and haven't noticed any opportunity for maggots, and only the occasional fly that gets in.

It could happen
Sometimes I had infestations of flies (probably carrion feeding ones) in my basement. They lasted a few days and then they were gone. I suspected a dead mouse in the crawl space, next to the basement, although I couldn't detect any smell. Maybe this is what happened.

I've seen a mouse or two run through here, so it's not impossible. I'll have to just accept that! :)

spectacular series! hope someone will sort them out… eventuall

Thank you!
I thought it might be a chalcid, but wasn't certain. I hope someone can tell me what it was and where it might have come from, into my house!
