Heimlich is a supprting character in the 1998 Disney/Pixar movie, A Bug's Life. He is a green caterpillar with a German accent, who originally worked as a clown for P.T. Flea's circus, along with Slim and Francis, until he, and the rest of the circus bugs are fired by P.T., when they accidentally burn him. He is then recruted by Flik along with the other circus bugs, when he mistakes them as warrior bugs who can help his colony fight off Hopper and the grasshoppers. Heimlich is very gluttonous and always seems to be eating. Even during a performance, he offered to help finish one of the audience's candy corn. The fly refused, but then it turned out that he got the candy corn anyway. Heimlich dreams that one day he can become a beautiful butterfly. At the end of the film, he sprouts a pair of tiny wings, which he can't even fly with, but this is enough for him to be happy that he is now a butterfly.
Heimlichh is voiced by the late Joe Ranft.
