Hi all. Wondered whether anyone can ID my new queen please? Found yesterday in meadow, around 5-6 mm. I actually thought she'd died in the night so didn't get a very good photo, sorry. I put her in a tubs and tubes set up as her gaster is small and I figured she's semi-claustral (and I thought she was dead so didn't wait for ID unfortunately) and I just checked and she's clearly extremely alive.
Any help would be greatly appreciated. One of the catches I made yesterday was clearly a spider when I got it home, so I don't know what happened there. Several of my Lasius niger have laid eggs though, and the Myrmica sp I caught a month or so ago has tons of brood.
