There are also jumping spiders. Many bugs can fly. Bees have long range and a rather powerful sting, and are great bombers. Mosquitos are fast but flimsy on defense. Wasps are VERY powerful fighters and not bad fliers.
Some bugs can swim.
Water bugs can swim FAST but they're not much good at fighting. Water beetles, on the other hand, are almost as powerful as wasps. One water bug can transport another bug on its back, but I forget which one. What gives all of this so much appeal is the painstakingly-done art for each bug. Wasps are debonair commandos, flying into battle wearing velvet tuxedos.
