Hello, caught two of these under bricks in our yard. Spring isn't quite here so, these are from last year. Can anyone confirm lasius ubratus? Need more information, let me know.

Looks like Lasius umbratus or Lasius speculiventris

Definitely an umbratus-group species. Probably one of the darker ones like umbratus or speculiventris. Try getting a good pic of the gaster in dorsal view.

Lasius speculiventris has no pubescence on the second gastral tergite, so assuming that she is around 6-8mm, this is Lasius umbratus. Lasius minutus would have roughly the same appearance in a smaller size (4-5mm), but with long standing hairs on the gaster. Measurements, always.

If you've enjoyed using my expertise and identifications, please do not create undue ecological risk by releasing your ants. The environment which we keep our pet insects is alien and oftentimes unsanitary, so ensure that wild populations stay safe by giving your ants the best care you can manage for the rest of their lives, as we must do with any other pet.

Exotic ants are for those who think that vibrant diversity is something you need to pay money to see. It is illegal to transport live ants across state lines.
