All three have aquatic larvae/nymphs.
On the one hand they are more ferocious than adults.
On the other hand, the young being aquatic I doubt

survive and grow after hatching with no running water to live in.

Hellgrammites are the aquatic larval form of eastern dobsonflies. They are fiercely predaceous and look a little like centipedes. Anglers often use them as bait.

Their pincers do exactly that...ouch, but they make great trout bait.
