I'm keeping Solenopsis invicta to research a working synthetic diet for the USDA. I caught some of these queens May 15, 2015.
I took photos of a few of the colonies. I had intended to brood boost the colonies, but haven't had time, so I just let them develop naturally. The biggest two colonies I have got their start in a byFormica GroTube XL, rearing their first nanitics in about 3-4 weeks.
