Overview

Tied sparse on a Tiemco 2487 curved hook, Eric's Midge builds a slim olive Superfine dubbing body ribbed with fine gold wire, then caps it with a glossy shell of Solarez Bone Dry UV resin that adds a segmented, translucent sheen much like the exoskeleton of a natural midge pupa. Black Veevus 14/0 thread keeps the tie-in points clean and the overall profile thin. With no wing or added bulk, it rides low and true, making it a dependable point fly under an indicator or dropped off a small dry during selective midge hatches on both stillwater and moving water.

Behavior & presentation

Natural Behavior
Midge pupae hang vertically in the surface film with gas bubbles trapped under their casings, struggling to break through the surface tension during calm-water emergence periods.
Where Trout Eat It
Fish sip pupae hanging vertically in surface film during tailwater midge emergences in the San Juan River. The UV resin shell creates realistic sheen imitating gas-trapped pupal casing as insect struggles to break through meniscus during calm-water hatches.
How to Fish It
Dead-drift just under surface or in film with greased leader to within 6 inches of fly. Use light tippet (7X-8X) for delicate presentation. Fish as dropper below visible dry or on its own during concentrated midge hatches in morning and evening periods.
Best Water
Work tailwater tail-outs, seams, and foam lines where midge pupae concentrate during calm-water emergence. Target spring creek flats and slow glides where fish develop selective feeding rhythms.
Strike Type
Trout sip the emerger with delicate rises barely breaking the surface; watch for tiny rings or subtle dimples and set gently.

Fishing strategy

Rigging Suggestions
Rig this pattern on a light tippet and use a strike indicator for best results.
Seasonal Timing
Most effective March through November with peak activity during cooler months. Fish morning and evening when hatches are most concentrated.
Pro Tips
This pattern is designed to sink and imitate a midge pupa. The resin coating gives the fly a little shine, making it more visible underwater.

Entomology

Midge pupae hang vertically in the surface film with gas bubbles trapped under their pupal shucks, struggling to break through the meniscus during calm-water emergence periods. Tailwater trout develop extraordinary selectivity to these size-specific presentations because midges emerge in such overwhelming numbers that fish can afford to feed exclusively on a single life stage, rejecting anything that doesn't match the precise silhouette and behavior of hanging pupae.
