Need Help To Find Out What Queen Species I've Got

[Ants4fun]

Likely Lasius Niger. Where was this queen found?

Looks more like a black Formica species- Lasius queen gasters normally do not seem to expand in length like this one has, they tend to be fatter instead of longer. Workers will give us the answer for sure.

I had a queen that had her gaster expand like that. I have a picture of her in the journal here: http://www.formiculture.com/index.php/t ... ger/page-2

Still, I think it is Formica.

I am unfamiliar with UK ants, but wow look at that physogastrism ("termite gaster" syndrome)!!!

I have seen gasters blow up like this in Lasius, though. If you caught her in August in the UK chances are she is a Lasius but we really need a close look to be sure.

Congrats on this beauty!
