I've found it interesting that even InsectoidAliens are depicted near human size (rather than supposing they're more insect size)--as far as physics goes, at least in Earthlike gravity a creature with an exoskeleton like that probably wouldn't be able to even move at human size (which relates to the SquareCubeLaw mentioned above ^^^). "Giant mutant ants" and such depicted in B horror movies would be implausible, unless they greatly evolved to the point where they wouldn't resemble ants at all anymore (no exoskeleton, and also huge changes to the circulatory system and such).

It's probably mainly to do with using human actors (something that is becoming less necessary nowadays though), plus the way characters are framed in a scene--if Insectoids were insect-size, you'd have to keep zooming the camera in at them when they speak and whatnot (and wouldn't see them in a normal group shot with the others), and the interaction with "normal sized" main characters would be distracted from that way. So there is probably, for those kind of practical or technical reasons, a lower constraint to size below, say, maybe a foot tall.
