I didn't expect to catch any more queens till next year and then I found these three weeks ago. I'm in Northern Ontario, Canada.
The first I found under a leaf in the corner of my driveway. She's around 7-8mm.
Apologize for the quality of the pictures but she's very small and doesn't seem to want to slow down at all.
The other queen is around 10mm, I found her the same day but walking along a path.
