Mantis

Why?

Because it's über cool: wiki Mantis

• Praying Mantis Eats Hummingbird
• Mantis vs Spider (Not for the faint of heart)

How?

Surprisingly there's not much choice for .eu citizens :-( I'll probably order chinese (Tenodera aridifolia) ones on ebay, then get some native (Mantis religiosa or maybe even Empusa fasciata) when I find it.

Food?

Any live insect should do.

For baby mantises my plan is to grow fruit flies.
