Acorn-dwelling non-slave-making parasite ants discovered

Ohio State researchers have discovered a super-rare colony of non-slave-making parasite ants, living in an acorn:

L. minutissimus is a unique social parasite in that it lives entirely within the colonies of other ant species. But unlike parasitic slave-maker ants, which raid and virtually destroy the colonies of unsuspecting hosts, L. minutissimus appears to move in and live amiably with its host. Such organisms are called inquilines.
