And my 2nd colony I believe its in the brachymyrmex family, also got in central MO. this colony does not cocoon even though they have sand inside.

Compare the first to Lasius alienus.

First is Lasius, probably americanus by the looks of it. Second is a Nylanderia sp.

Their overall build.

Brachymyrmex spp. have cocoons over their pupae and would have much shorter antennae than these. You also wouldn't find any dark-colored Brachymyrmex anywhere around central Missouri, only the light colored subterranean species Brachymyrmex depilis.

Nylanderia is often noticeably larger than Brachymyrmex. And there aren't any dark-colored Brachymyrmex in Missouri. Your Nylanderia appear to be Nylanderia faisonensis.

thanks for everyones help, The Nylanderia had a hard time getting her 1st workers. I think she had about 6 workers by the time I put her to hibernate, I took her out on March and doing very good now.
