i hate mosquitoes more than roaches...
look up a camel spider, i think thats the name of it, they are some ugly fuckers and they live in Iraq and shit so the soldiers see them a lot, and they try to hide in the soldiers' shadows for the coolness, therefore it looks like they are chasing them. i know a guy who was in the war in Iraq and one was following his shadow, he panicked and shot at it and got in some huge shit for doing that on base.
