Insectoid Aliens

Insectoids are creatures which share many similarities with Earth arthropods, such as multiple limbs, insect-like mandibles and an exoskeleton. Sometimes they will also have compound eyes and antennae. It is possible for a aliens to be both insectoid and humanoid, as bipedal insectoids with only four limbs often have a fairly humanoid body plan, e.g. Prawns or Irkens.
