they all survive with about 40 but their mom is hungry. Do you have any idea on which food is favorite for this sp?

Anything smaller then they are, but you could try flies.

Local pet shops may often stock up on fruit flies that you can purchase.

Large species can take crickets, though in the wild I've seen jumpers eat termites (I had exposed a small nest in a rotting tree stump in our back yard. When i returned maybe a half hour later there was a small jumping spider with a termite in its jaws). Ants are sometimes also taken. Yeah, basically anything they can subdue.

Actually fruit flies might also be goof starters for the babies, though you could also possibly try springtails. Those, however, you'd need to go out back to get. :/
