Trico Poxyback
The little mayfly that produces so many big fish.
These nymphs are terrible swimmers, much to the delight of waiting trout.
Trico hatches tend towards the middle of summer through October, in the southwest though they can occur in February.
Nothing will test your fly fishing skill like this hatch.

Sonia Dyer –
Used the Trico Poxyback during a late summer trip and caught several trout. The fly’s slow movement matched the natural nymph perfectly. Great for targeting fish that are waiting in still waters.
Tracey Miller –
Felt the fly worked well during a mid-summer hatch. The poor swimming action made it stand out to the trout. A solid choice for fly fishing in the southwest region.
Sue Walsh –
Caught my first trout of the season with this fly. The timing matched the Trico hatch perfectly. It’s a reliable pattern when the weather is warm and the water is clear.
