New to Britain in 1926 near Southampton, the species has a two year life cycle, and is remarkable in that moths are rarely seen or bred in odd years, appearing only in even years.

Day-flying species, and like many of the clearwings with the recent popular use of pheromone lures, this species appears to be more widespread than previously thought.

The scientific name flaviventris refers to it's yellow belly, which separates it from the very similar Current Clearwing.

Pheromone attractants: SAL (MYO+TIP)
Pheromone activity times: all day Peak 1pm-5pm.
