[leps-talk] MALE x FEMALE emergence

[Woody Woods]

It would seem to prevent or at least reduce the inbreeding we might expect if the males and females emerged at the same time. Just why females rather than males first I dunno, but here's a long-shot thought: males in some insect species will wait for hatching females
but not commonly the other way around. For females to get a head start getting away before their brothers emerge would be in keeping with female choice, which is more common than male choice in mating systems. -Woody
