Extended Body Drakes

Brown
should be in sizes 8 and 10.  Gray should be 8 to 12 and green should be in
sizes 10 to 12.

There
is a lot of confusion concerning the Drake mayflies.  

Some think Brown
Drakes are March Browns, but they are two different mayfly species.  

Some
anglers believe Gray Drakes are Green Drakes in their egg laying (spinner) stage
but they are actually two different mayflies.  However, the Gray Drake is a
good imitation to use during the Green Drake's spinner stage.

The
important thing is having the closest possible color and size as the
natural.  Having these three on hand should fill that need.
