>>1118046Yuri is quite widespread in all eusocial insects, actually: I am particularly fond of the female-female interactions identified in the Japanese subterranean termite Reticulitermes speratus, a species for which pair forming is absolutely vital because a partner is necessary for proper grooming behavior and the associated protection against a slew of often-fatal bacterial and fungal infections (unlike ants, termites cannot groom themselves beyond their antennae and always require a partner for cleaning.) Since the sex ratio is strongly female-biased and a nest-founding partner is necessary for the termite's survival, female-female pairs commonly occur in this species, where the queens help each other construct a burrow and share their resources (which is unusual since pleometrotic queens are often expected to compete, but no such competition could be found.) Colonies of female-female pairs also end up exclusively female, for such a couple never produces males - this is thought to be the reason the sex ratio is female-biased to begin with.
Even the nest-founding behavior is reminiscent of Marimite or Sonohana - one female gently leads her partner along to the nesting site, so you could think of the former as a talented, admirable onee-sama who initiates a younger girl to the pleasures two girls can enjoy together and forms a pure yuri bond with her (since mutual grooming is extremely important in termites, I guess this also calls for plenty of bathing scenes where they wash each other's backs, though the onee-sama would use this as an excuse to molest her flat-chested partner. In colonies where one queen is smaller, the presence of her partner also allows the former to develop faster, so I guess the onee-sama would also enjoy cooking odd dishes for her lover that are supposed to make her breasts grow.)
Incidentally, when not practicing yuri, this species propagates by means of a loli harem, where neotenic daughters of the queen mate with the king.
