Fusion Insectoid

Insectoid mutates have had their DNA fused with the DNA of any animal of the class Insecta, comprising small, air-breathing arthropods having the body divided into three parts (head, thorax, and abdomen), and having three pairs of legs and usually two pairs of wings. It also includes any small arthropod, such as a spider, tick, or centipede, having a superficial, general similarity to the insects. It also includes the various prehistoric species.

Traits
These mutates tend to have the behaviors, as well as the bodily features, of the insects and/or other arthropods that they are fused with. For instance, in terms of bodily features, they may have chitinous skin, multiple limbs, large, compound eyes, antennae, maybe even abdomens/tails and wings. In terms of behaviors, they may tend to either be loners, or want to be a part of a group, depending on what insectoid creature they are fused with (though these aren't always the case).
