Description of the Olive Flashback Caddis Pupa - Fly:
The Olive Flashback Caddis Pupa is a Caddis pupal pattern designed to imitate the deep pupal stage of the caddis, with an impressionistic representation of the translucent air sac surrounding the insects body. The olive shade best represents the Rhyacophila Caddis species found most commonly in most Western waters. As Gary LaFontaine noted in his book Caddis Flies having a good deep pupal pattern to fish as along the bottom just before an evening caddis hatch can be the key to moving fish before they transition to the hatching insect. The Olive Flashback Caddis Pupa would be just such a pattern to have in your Caddis fly assortment.
