Catapoid

The Catapoids are a sapient race of female shapeshifters which alternate between two forms. During the day, they look like beautiful humanoids. At sunset, they become monstrous, caterpillar-like insectoids.

Biology
In their humanoid form they resemble blue-skinned females with elfin ears and a pair of short antennae. Their hair can be purple, blue, red, orange, brown or yellow. Their language resembles a series of hisses and clicks. They seem to require the same environmental conditions as earthlings.

At night, they rip off their skins to reveal a larger, much more monstrous insectoid form with two-fingered hands, an armored slug-like body, a spiked tail, sharp teeth and bulging eyes.
