Baetis Muskrat Sparkle Dun

The Muskrat Sparkle Dun is a variant of my Baetis Sparkle Dun and is an imitation of the hatching Baetis. The Muskrat Comparadun falls in the class of no-hackle mayflies. You’ll never go wrong with a muskrat comparadun. This variant has an explicit olive tone, but is subdued by the wooly quality of the Muskrat dubbing. 


This is in my series of Baetis patterns that I use from the start of June, and for about three weeks. The colors are subtler, but this one is clearly more olive than the grey/olive variant.

The colors of the first and second generation hatch are different in my waters (mostly Hedmark, Norway). The first generation being lighter/paler and more grey, whereas the second generation of the bug have darker olive/brown olive tones.

The dubbing on this one is Hends fabulous Musk Rat dubbing. Makes any fly look buggy.
