If there is one fly that has become a staple on the end of my clients leader during the Spring, Fall and Winter months, Parrott's Chironaflash Pupa is at the top of the list.
There is just something about this fly that catches fish and we all set out each and every fishing trip to do just that.
Simple to tie and effective, this pattern is a must have in your box!!!

Here is a little history about the Chironoflash Pupa in a Q&A with Steve Parrott:
“The genesis of your fly; how it happened to spring from your vise; what was the inspiration?”
I wanted a simple midge that was easy to tie, durable and worked in a variety of situations( tailwater, freestone streams and small creeks) I used the midge tubing on the body for durability and appearance (shiny and realistic looking). I then wanted to add a little flash to the fly to give it the appearance of a gas bubble that is present when the midge is emerging. The head color was selected to give the fly a little contrast in the water from light to dark with a darker wing pad (medallion sheeting) on the top like the naturals have.
“How long have you been fishing it…where and for what?”
I began tying this fly in 1997 for the South Holston Tailwater in Eastern Tennessee for the darker midges I was finding in every sein sample I was collecting from the river. I felt that if I added a little flash to the fly, it would act as a trigger spot on the fly to entice the trout to eat that one over the naturals. When I moved to Colorado in 2006, I used this fly in the Canyon and “Dream Stream” with great success. I could not believe the fish I was catching with this fly but if it worked back East, why would it not work here in Colorado? The fish that were causing me problems on the river being picky and stubborn were now moving with reckless abandonment to eat this fly.
“How do you fish it?”
The fly is best fished on a two fly indicator rig with enough weight on the leader to keep the flies in the appropriate zone the fish are feeding in on the given day. If you are fishing this fly right along the bottom, it does not work as well because the fly is designed to imitate a midge (and also a Beatis, believe it or not) suspended in the water column making its way to the surface to emerge. The best placement for this fly is in the top position of a two fly rig.
You can also fish as a dropper below a dry with some sort of weight between the dry and the Chironoflash to get the fly down into the feeding zone. This works great in shallow water or riffles when fish are pushed up feeding.
