Why Are There No Giant Insects?


Is it because my friend Bob The Bug Guy has ruthlessly sent them to extinction? Is it because god didn't want them large?

Noooo, it's because bug breathing is done with a whole different system than with vertebrates. In an ancient atmosphere, with a much higher oxygen content than we have now, it was possible and there were such creatures (though not quite like in the picture)!

Robin Lloyd, LiveScience Senior Editor, has the full story.

Contrary to John's statement ....there are many large insects....I have personally killed many in the last 14 years...John is scared of big bugs thus that is why he tries to believe they don't exist..His testicles were attacked by a large beetle many years ago and he has been scarred emotionally ever siince.
