Very cool to see a fishermans picture, which I suspect is more realistic than many images on the web.
I crafted something I think should work. I took some x-small black mono eyes and cut them from post. I then used super glue to attach them to a #14 2312 Tiemco hook. Using clear mono "thread", I then tied in an extended body made from the braided end of a Cortland slip-on leader loop. Build a clear body with SHHAN and unravel the end of the braid and you've got a pretty good imitation, I think.
So, it is a white LED headlights from Coast (Costco). I have used it before to show samples. You have to play with angle and background.Very cool to see a fishermans picture, which I suspect is more realistic than many images on the web.
Is the light in your first picture a white LED?
There are fly patters for these.
Heck I even caught a fish with one but I suspect it was an impulsive take when green chironomids were around and had nothing to do with glass worms on that day
