A nice acrylic yarn that I came across at The Hobby Lobby, Stella by Tamm (Omega). 95% acrylic and 5% metallic nylon. One skein per 371 yards at 3.52 oz. Comes in 25 colors, many of them embedded with a Krystal Flash weave. Plenty of buggy colors too. Under $5 bucks a skein at the Hobby Lobby, same price over at Creative Yarn source. The texture of the fibers would make for nice nymph bodies if the yarn is wrapped straight on the hook, or chopped and dubbed.
