Alder Moth
Acronicta alni

(Linnaeus, 1767) 2281 / 73.036

Morley's Final Catalogue: Apparently rarer than in 1890, when it had been found at Woolverstone, (not Ipswich by Bree); Glemham Magna (Bloomfield); Needham (L); Finburgh (Levett); Culford and West Stow (Wrt). Thence we know it only in a wood near Barham Green (Sparke) and a larva at Bungay (Mn).

Recent status: With the advent of electric light-traps, this species has become much more regularly recorded.

Habitats: Damp woodlands with Alder trees and Birch Woodland.

Life History: The young larvae resemble bird droppings but when mature they are banded yellow and black with distinctive club-shaped hairs along the sides.

Recorded in 46 (79%) of 58 10k Squares.
First Recorded in 1960.
Last Recorded in 2022.
