Peanut-head Bug (Fulgora laternaria)
![]()
This weird looking creature is an insect, in the family Fulgoridae of the order Homoptera. The Fulgorids all have enlarged foreheads, but it is most remarkable in the peanut-head, so named because its head looks like an unshelled peanut. It grows to about three inches (8 cm) long.
The peanut-head can't bite. Its mouth is like a straw, so all it can do is suck juices from plants. That's why it needs a lot fancy defenses to scare away predators, like it's strange head.
Scientists think that the head is supposed to imitate a lizard's head, and animals that don't eat lizards are scared away. It is part of a complex anti-predator scheme the bug uses. The peanut-head has large red and black spots on its underwings that look like large eyes when the bug spreads its wings. If these don't scare away predators, the bug releases a skunk-like spray. In the rain forest there are so many things that want to eat the peanut-head that it needs a lot of defenses.
