Thanks guys.
It is a great cicada, Zach, I agree. The fisherman who gave it to us really matched the size and profile of the bugs. He had been fishing there the previous weeks and we met him by chance on a stretch of river bank. I’m not quite sure of the foam used for the body—but in my attempts to duplicate it–two stacked black bug bodies worked, or trimmed & creased 3mm black foam worked. He used quite a bit of Zap a Gap on the thread ties. The lower profile fooled spookier, more weary fish that were sipping. “Fish the Splat!” was his advise, as he said to fish it dead drifted when you spotted risers on flat water.
Our bomber-style flashier bugs were the ticket in choppy water, where aggressive twitches and bubble trails would lure up violent strikes.
