Spindle knot-horn

Description

Nephopterix angustella, commonly known as the spindle knot-horn, is a moth in the Pyralidae family. With a wingspan of 20–25 mm, this species is easily identified by a distinctive blackish patch of raised scale-tufts near the head. It can be seen in hedgerows and scrubby areas throughout Europe. This moth has two generations per year, typically flying in June and July, then again in September and October. The larvae feed internally on the berries of Euonymus europaeus (spindle tree), causing notable damage to the berries as they consume the internal structures.
