I have two Formica colonies started from queens last year. One is Formica pallidefulva and she started laying eggs maybe a month and a half to two months ago. She's already got some fresh workers born for the year and it looks like the colony will continue to grow well into the autumn. The other colony I have is interesting though, Formica pergandei.
Formica pergandei is a social parasite of other Formica species. That is F. pergandei queens can't start a colony on their own. They have to invade established colonies of hosts and replace it's resident queen, usually by assassination and stealing the colony odor by rolling in the queen's juices, etc... so the host workers don't turn on here.
