Araneae: Salticidae
Hypoblemum albovittatum
After the male has finished inseminating the female, he has a problem.
He needs her to live to lay eggs and propagate his next generation. As a result, she is safe from him.
But she can't think of a single reason why she needs him to live now that she's got his sperm. His only potential use is as a convenient home-delivered meal. He is not safe from her.
As he is not totally oblivious to these facts and has finished his love-making, at the instant he releases her he leaps over the edge of my computer stand to where he is safer by being out of her sight, and the two go their separate ways.
Or they would have done if I hadn't recaptured them both in separate containers and given them different parts of the garage to play in. Two Jumping Spiders, one of them newly pregnant, is potentially too many spiders running around my computer.
