Nah. Weirdly enough it was the character with the arthropod features I was investigating the concept for but now I wonder if I should've done that for the illithid so I might look into that. It was relevant to the other character because the actual arthropod features (wings) are missing by the time of the story so it was going to be one of the "hints" that they had her labeled as the wrong species but first of all it just didn't fit creatively, it was much too overt to the extent it didn't even make logical sense for the mixup to happen but also as you see here the science doesn't follow either it's only spiders and the like that have it, not dragonflies.
