Researchers in Japan are studying partnerships between termites. Like other monogamous species, termites frequently partner up to increase their chances of survival.
The biologists found when female termites are rare in certain areas, male termites will pair up and build a nest together. They may do this because termites tend to be "social" creatures. The study found that these male partnerships are especially prevalent in places where there are numerous predators, likely, as a way to provide greater security.
Researchers also found that the male-male termite partnerships will ambush and attack the nests of male-female termite partners. These attacks often result in them killing the male in order to mate with the female. The study found that after this, the successful same-sex partnerships will be broken up because only one of the male partners can mate with the surviving female.
A reason why this is being studied is because some biologists hypothesized like the same-sex pairings in insects such as fruit flies, these partnerships were happening because male termites were being mistaken for females of the species. This study provided evidence that these termites were pairing up because there were survival and evolutionary benefits to having a same-sex partnership.
