Not nice when they invade your house, but Ants are incredible creatures. The other week I saw one carrying a dead fly through the grass. The flies wings got caught on a blade so it couldn't move it. Then along came another ant and pulled the blade of grass out of the way:)
Wow this is fantastic! I agree ants are very interesting creatures. Can't stand seeing them wwhen they get in the house but they sure know how to work as a team!
