Dobsonfly larvae (Family Corydalidae)

Key features:

- set of "pincers"
- tail hooks
- stout body with six legs
- lateral appendages
- with gills underneath
- size range: 3/4" - 4"

Dobsonfly larvae are often found clinging to rocks in the more swift areas of the riffle. These larvae are predacious and spend much of their time hunting for prey. They have stout bodies with tough skin. The appendages on the rear section of this organism are called "lateral appendages" and should not be mistaken for legs. If you find a dobsonfly larva in your seine, grasp it directly behind the head to pick it up. This makes it impossible for the larva to pinch you. Note: These larvae are also known as "hellgrammites."
