As far as I know, everything on that page has six legs, and exoskeleton, and possibly three body segments (harder to tell).
Your right, no more Spiders or Scorpians in that section.
Though to be truthful I didn't mind. I just found it funny
Though oddly enough I am having trouble finding insects off of the main section.
Ohh do we want ALL the families of Beetles? I guess Ill post all of them
Edit addition: NEVERMIND! There are at least over a hundred beetle families. While I want at LEAST 100 Beetles (and Butterflys/moths) there are enough in here to make an individual insect ark. I think we may actually need an insect limit.
