From the designer, Tyler Boroff:

While taking entomology samples late winter on an Arkansas tailwater, I noticed these two-toned midge larvae wiggling all over my bug net. While thinking to myself ” I wonder if a two-toned larvae would make a difference on the water?” Turns out it did make a difference; thus the Two Timin’ Larvae was born! Using red and pink resembled some of the annelids that I saw on the net.
