Already found another one this morning. Butterflies have no nerves or blood vessels in their wings. Because of that, Janine Bendicksen has successfully performed what is likely the first ever wing transplant.

From the (British) Amateur Entomologistsā Society website definition of aedeagus:
In some species, for example some crickets, the aedeagus is also used to release a spermatophylax. The spermatophylax is a gelatinous substance that the female insect consumes and this provides sustenance to the female.

Freshwater limpets will attach themselves to any smooth surface available to them. This apparently includes the carapace of beetles, as shown in this observation I stumbled upon yesterday. Another user found a paper describing the phenomenon, and while Iām still trying to find the full text of that paper, it seems limpets may actually use beetles and other aquatic insects as a method of dispersal.
