Leptanilla japonica is an uncommon highly migratory, subterranean ant found in Japan. They are tiny insects, with workers measuring about 1.2 mm and queens reaching to about 1.8 mm, and live in very small colonies of only a few hundred individuals at a time (as compared to the 60,000 to 20,000,000 individuals of legionary ant colonies.) Its sexual development follows a seasonal cycle that affects the colony’s migration and feeding habits, and vice versa. L. japonica exhibits specialized predation, with prey consisting mainly of geophilomorph centipedes, a less reliable food source that also contributes to their high rate of nest migration. Like ants of genera Amblyopone and Proceratium, the Leptanilla genus engages in larval hemolymph feeding (LHF), with the queen using no other form of su
