The Hebikera is a long, flatworm-like insect with four pairs of wings distributed over the body. It seems to fly in an undulating fashion, sort of like how an eel swims underwater.
It is a large insect, nearly as long as the tolmekian airship Bumblecrow, and a swarm of them is strong enough to take down large aircraft, like a Bumblecrow. It has a large pair of mantibles and a large flat mouth. Its head is armored like a crab and it has four eyes.
The name suggests "Snake (Hebi) Cricket (Kera)". Their larve are called Minonezumi.
