>>33239605Yes, the entire line evokes bugs and is based directly on an insect, but they're not Bug types. And that's OKAY.
Flygon is a dragon, so it's Dragon type. And they could've made it Bug but they chose not to, because Flygon is supposed to be the spirit of the Desert or whatever. Trapinch buries in sand, and the whole line is sort of inseparable from the element of Earth. It represents deserts in general.
So, while Vibrava is blatantly a bug, Trapinch and Flygon were both intentionally designed to LOOK like bugs without actually being insects. Flygon has things that look like antennae, insect wings and compound eyes, but none of it is actually real.
