Sesiioidea

Sesiioidea is a superfamily of moths belonging to the order Lepidoptera. These moths are commonly known as clearwing moths or sessiid moths due to the transparent or semi-transparent patches on their wings, which are a distinctive characteristic of many species within this group. The transparency is a result of the scales being reduced or absent in these areas. Adult sesiioids often exhibit mimicry, resembling wasps or bees in their coloration and wing patterns, which provides them with a degree of protection from predators.

The larvae of sesiioids are typically wood- or stem-boring insects, feeding within the tissues of various plants. This endophytic lifestyle means they can be considered pests in certain agricultural or horticultural contexts, particularly when they infest economically important crops. The pupal stage occurs within the larval burrow. The superfamily Sesiioidea encompasses two families: Sesiidae and Brachodidae. Sesiidae is the larger and more widely distributed family, with a global presence. Brachodidae is a smaller family, primarily found in the Old World. Research into Sesiioidea continues to explore their ecological roles, evolutionary relationships, and potential for biocontrol applications.
