So I obtained a jumping spider (the perks of working as an outdoor educator) -- and it's keeping ok in the tank (I can give you the scientific name in a bit when I grab my book and copy it down) -- problem is it won't eat!

It has a woodroach and ladybug in the tank so far -- it's been too cold to get crickets here at camp -- but he's not touching either one -- should I find something more to his taste or wait it out?
