The Large milkweed bug

The milkweed bug, "Oncopeltus fasciatus", is a medium–sized hemipteran of the family Lygaeidae. It feeds mainly on grains, particularly those of the milkweed. Like all hemiptera, it feeds through a long mouthpart known as a rostrum. "O. fasciatus" is commonly used in science due to ease of rearing and ease of dissection.
