Just found July 14th. I'm stoked, but I have no idea what kind she is. I'm thinking Lasius but she seems big for that species (my uniformed newby opinion here).
Found on a sidewalk around the edge in the grass.
About 8-10mm. She's in an AntsCanada test tube in the pic, if that's a reference for you.
Kentville, Nova Scotia, Canada
Any help would be great. She was a bit rambunctious for the first day or two. She has since calmed down and laid 4 eggs last night.
