Dictyobia aren't doing cool things at each other

Assembled some adults into same-sex and different-sex pairs. They pretty much ignored each other, didn't even mate. Evidently at least some of them (esp. fem, due to eclosing later) are sexually immature. I mean I was expecting some sexual immaturity since all my other hoppers had to feed for a number of days before mating, but I'm kinda disappointed there wasn't some sort of communication dance even the unripe adults would do.

Also, I observed some specimens to switch the asymmetry of which wing was raised higher than the other (not in relation to social interaction; just spontaneously, before I even housed them together).
