I found nine of these tiny Hypoponera sp. queens on my black light 7-12-2015 in Trabuco Canyon, CA.
I put them in four test tubes--three groups of two, and one group of three. So far half of them have removed their wings and a couple of them have died. None of them have laid any eggs yet.
I have tried keeping these before, and none of them have ever laid eggs. I hope one of these times I will get lucky.
