Moved from Lasius umbratus.

Moved from Ants.

Formicinae: Lasius
Lasius umbratus. These have mating flights in fall, but the mated females overwinter, then invade (most likely young, small) colonies of the host L. alienus in spring, kill the host queen and if lucky, become adopted by her workers.

 
Thanks!
It looks very dark compared to the others on the page.

 
It does indeed.
And not pubescent, either. I'd better go back into the literature and check on this one. Keepin' me honest, John.

 
I have sent an email
to my nephew who probably still has the ant to check the images for color and darkness to make sure that taking the images through the glass (or any processing that I did to reduce the glare) didn't change things too much. I will also check the unprocessed images when I get home late tonight just to make sure my processing is honest!

I will also check with him for the habitat where it was found.

 
This individual seems to have very little pubescence.
Lack of pubescence on the gastral dorsum indicates L. speculiventris, but this one is supposed to have failry evident pubescence on the appendages, imaginable but not clearly visible in these images. When you find out more, let us know. I'm thinking we might need a guide page for this latter species. The species is vanishingly rare and limited to high-quality sedge meadows and seep-based woodlands with intact hydrology in the Chicago area, but appears to be as bit more catholic in habitat choice in your neck of the woods.

Can you check on the body length measurement, too?

 
He said
He said "found her walking around maybe they had a nupital flight."

So I guess somewhere in his neighborhood (NJ pine barrens, lots of other brush, not too far from a creek)

He said "she was a little darker more black than brown"

I could have gone either way looking at the originals, some looked the same as these images while in others I couldn't tell if they were a dark-brown (but lighter than these) or just glare from the flash on glass.
