Found these amber coloured ants crawling on my burr oak tree near Medicine Hat Alberta.
Not sure if they are latipes or coloradensis or ??

These do not look like parasitic Lasius.  These are either: L. americanus, L. neoniger, L. pallitarsis, or L. crypticus.  Can you get a shot of the mandibles from the front?  That will make it far easier to ID.


Hi there! I went on a 6 month or so hiatus, in part due, and in part cause of the death of my colonies. 

However, I went back to the Sierras, and restarted my collection, which is now as follows:

Aphaenogaster uinta, Camponotus vicinus, Camponotus modoc, Formica cf. aserva, Formica cf. micropthalma, Formica cf. manni, Formica subpolita, Formica cf. subaenescens, Lasius americanus, Manica invidia, Pogonomyrmex salinus, Pogonomyrmex sp. 1, Solenopsis validiuscula, & Solenopsis sp. 3 (new Sierra variant).

You need to check the number of teeth.
