Insect thunderdome: Two bugs enter, one bug leaves!

[Incubus]

There aren't that many impressive bugs around my house, but after watching the Discovery channel for countless hours (its summer vacation), that cool video about the Great Bee Massacre I thought it would be fascinating, albeit somewhat cruel to put two bugs in an 'arena' with the idea that they would fight each other to the death. What cool match-ups would you like to see?

Mantis vs Scorpion: This would be a cool match-up because I would imagine this would be a fight in which the victor would most certainly be eating the loser. I saw this fight on the Discovery channel once and the Mantis won, but things could have gone the other way around if that Scorpion got a hit with his stinger.
