In this most recent trap, a cousin of the Udea olivalis managed to sneak in: Udea prunalis. This moth looks almost exactly like Udea olivalis, except it’s a slightly different color and has dark markings on its wings instead of white ones. Unlike olivalis, it is known that this moth feeds on blackthorn, which coincidentally is also the meaning of prunalis. When shown side by side, the family resemblance is really uncanny!
