Length: 4 - 6 mm
Members of this family are often attracted to lights, and may also be found on the flowers or leaves of plants growing near water.
Male Ptilodactyla sp. (pictured) have improbably pectinate, (comb-like) antennae. Presumably these are used to hone in on pheromones released by the female. Female members of this genus have filiform antennae. In genus Paralichus the antennae of both sexes are serrate.
For ones peace of mind, it is probably a good idea to refrain from trying to identify members of genus Ptilodactyla to species. For that you would need a stereomicroscope, a dissecting kit, an entomological library, and considerable patience.
