Just an addition, it's probably obvious but worth mentioning. You need to be sure that the food supply hasn't been sprayed with anything, so don't go helping yourself to people's hedges unless you're sure they're safe.

I've kept Eurycantha calcarata, Oreophotes peruana, Peruphasma schultei & Carausius morosus but had to sell up because I couldn't find enough food for them. If you've got an abundant supply of ferns then Oreophotes peruana (Peruvian Fern Insects) are really stunning.

Here's one I kept moulting (I've got pretty much a complete sequence but won't bore you )

Searyan, you have clearley been mis informed by someones.

I think you mean that snails are Hermaphrodites. But they can't self seed, as you call it.

You DO need 2 snails to end up with eggs.

Hayley - Don't feel cruel for freezing eggs. It's very humane as it is just an egg, if you search round the tank every couple of days, you will get the eggs early and the snail inside will hardly even be developed.

I would recommend GALS for your son, but also Millipedes as already mentioned.

Giant Hissing Cockroachs are also another good pet, a little creepy for some people, but once you get used to them, and they get used to you they make great little pets, with lots of character, especially if kept in a small colony.
