The caddis emerger is tied in such a way as to really excite trout. Most times it is tied full, utilizing multiple hackles, spikey bodies and a wing. While the wing is not necessary I do put them on a few of these flies. The colors and sizes can also vary but I like the tan, orange and olive colors.
This big boy is a good representation of the "October Caddis"..it a big fly and does quite well on getting those wary trout to strike.
