I just got one of these guys, I absolutely LOVE jumping spiders![]()
How do you tell male from female with them?
All male spider have these sex organs called pedipalps. They use these to fertilize female spiders.
The picture below shows a male spider's pedipalp zoomed in.

Sexing jumping spiders are quite easy, males have larger muscular legs while females have smaller less muscular legs.
Female jumping spiders usually are fat(look well fed) while males are skinny. The easiest way of sexing these spiders is looking at their pedipalps, males have enormous pedipalps while females have very skinny and small ones. Male spiders are almost ALWAYS smaller than females.
@always4lora he was about an inch long in these pictures, he is now a little over an inch.
