If I could only have one fly in my box this would be it. The pumpkinhead is nothing more than a baby woolly ****** but it is the colours that make it irrestistable to trout. I will darn near guarantee that whatever stillwaters you fish you will catch fish on this fly. I will almost beg you all to tie this pattern and give it a go come spring. It's effectiveness only increases when damsels are on their migration.
Several people and flyfishing clubs have put out videos on You Tube and various other forms of media complete with tying instructions. If you google the phrase, "pumpkinhead fly" you will find more info than you need. The original was tied on a size 12 2xl but can be tied from size 14 to size 8.
Enjoy and if you're sold I would love to hear your experiences with the pattern in 2012.
