minus-squareMachinist@lemmy.worldlinkfedilinkEnglisharrow-up7·14 days agoCorrect! Insects have spiracles that basically passively exchange air. Max size is basically determined by this. IIRC, some caterpillars only stop growing and pupate when they run out of a growth hormone. I always wondered what would happen if you grew them in a high oxygen tank and supplemented their diet with the hormone. Maybe get a Mothman that way.
