Formicacida
Quite contrary to wiki, Formicacida (Weak) actually do Cut, Stab and Acid.
Not sure in what proportions, its a bit hard to test this one.
Chomper
Chomper Young does 92 Impact, 34 Cold.
Atrax
Atrax Young does 37 max damage. We know 10 of this is Impact. The remaining 27 is shared between Cut and Stab (we know Cut has at least 8 of that). Some testing still to do here. I'm currently trying to acquire an armor that will allow me to resolve this one.
EDIT: Now resolved. Atrax Young does 10 Impact, 13 Cut and 14 Stab.
