Male-Male Termite Pair Makes Nests (IMAGE) Kyoto University Caption A male-male termite pair makes nests, just as heterosexual termite couples do. Male Japanese termites form homosexual couples when no females are around -- and when the chance arises, they take over a heterosexual couple's nest and kill the male so that one of them can mate with the now spouseless female. The study supports a theory that homosexual couplings in invertebrates have evolutionary advantages. Credit Nobuaki Mizumoto Usage Restrictions Please credit Nobuaki Mizumoto.
