They are quite enthusiastic about the breeding part of the project, maybe not as much about the last act.
"Females become receptive to courting males at about 8-12 hours after emergence. Males perform a sequence of five behavioral patterns to court females. First, males orient themselves while playing a courtship song by horizontally extending and vibrating their wings. Soon after, the male positions itself at the rear of the female's abdomen in a low posture to tap and lick the female genitalia. Finally, the male curls its abdomen, and attempts copulation."Actually, from watching the process, I would include a second step, before the tapping, etc.: the male chases the female all over the place, both of them running. This couple had paused for a breather during the chase.
Too bad they won't get a chance to raise a family; they are already in the spider's jar.
