This topic is about the Insect Family Corydalidae

Hellgrammites are the vicious larvae of the Dobsonflies, some of the only trout stream insects which pose a biting threat to the angler. The pincers of the adult are even more frightening that the larva's, and they're aggressive enough to use them once in a while.

This family's life cycle does not create good dry fly opportunities, but the larvae may be eaten by trout year-round. They are a secret told only by stomach samples of well-fed trout. Read more...

There are 6 more specimens...

Buggy,

I don't know what Ontario regulations say about "picking" these larvae. However, provided that there is no prohibition against it, hellgrammites can be found year-round. The larvae spend as much as three years in the aquatic stage, so individuals of various generations (sizes) are available to you (and the fish) at any time.
