With Vermiculation coloration features a medium to dark dun base with irregular splotches ranging from dark gold to silvery white, resembling the mineral vermiculite. While the dominant color remains dun, these contrasting patches create natural color breaks that enhance the overall appearance. This unique pattern adds depth and texture, giving flies a realistic, “buggy” look that effectively mimics natural insects. The vermiculated effect makes it a valuable choice for fly tyers seeking lifelike and visually dynamic fly patterns.
