What Does This Buzzer Imitate
The emerger is the pupa that is resting just prior to hatching, loved by Rainbow and Brown Trout. These flies hang like the natural emerger it imitates. These use cdc or materials which are extremely buoyant.

Emerger Flies Imitated By Suspenders
Trout feeding on an emerger can usually be seen visually like dry fly feeding fish. Many people mistake a trout feeding on an emerger as a fish taking an adult fly which is not the case. This can easily be distinguished by watching the way the fish is feeding. If the trout is rising dorsal fin, tail, then kicking down either creating a bulge or splashy rise it is usually feeding on an emerger and the perfect time to use a suspender buzzer. Large trout feeding on emergers usually just create a bulge. The key is to see if the fish is showing its head, and if it is not then it is usually feeding on an emerger just subsurface and this is the time that you must fish with emerger type patterns like Suspender Buzzers
Fishing Techniques
These buzzers can be fished singly or on droppers. Use floatant such as Gink if neccessary and case using a tapered leader to ensure that the fly unfurls through the case. Watch and wait, trout will bulge then kick down, takes can be very fast with these buzzers
