I like spiders, I keep them as wild pets, I particularly like the orb weaver spider, a very nice 2-5in (5-12cm) dark black spider with a nice fractal yellow/white paturn along it's abdomin, (very small head so you don't have to worry about the eyes too much), they mostly just sit in there webs (wich can get as much as 3 feet (a meter) acros) in the middle of a few white stripes that it has weved into it and wait for some small flying thing to fly into it, I've heard they have a rather potent (though non-leithal) venom, luckily I havn't been biten.
when ever i find one of these guys I try and feed them bees and crikets and just about any fleshy bug I can find that has enough surface aria to get stuck to the web (the strands are rather far spred out, the web is designed to catch butterflys and moths mostly)
about the only thing I wouldn't feed to these guys would be a dragon fly wich is the coolest animal I can think of
I also like ants, there is a large colony under a brik in my back yard that I feed (sugar, meat, other ants) during the summer, I try to keep them healthy enough so they will survive the winter, the colony has survived for about eight years
