Fly Fishing

The unique appearance of the nymph is strikingly different from any other genera. They possess a large carapace or shieldlike structure which completely covers the upper surface of the thorax and abdominal segments 1-5. The three tails are very short and approximately equal in length. Both carapace and head exhibit hornlike projections. Adults are characterized by a thorax that is unusually large and an abdomen that tapers sharply in its rear half. The middle tail is very short and the hind wings are almost circular in shape. Baetisca does not appear to produce a hatch of any significance to the angler.
