What does this tag actually mean? As it is, it's undefined and seems to be used inconsistently. I think it should be used for insect-like beings that don't fall into another category of arthropod but are not insects; whether due to limb count or something else.

Pinsir and Heracross, for example, would be Insectoids, and not Insects. I think the implication should be undone, and Insectoid should imply Arthropod.
