Feathered Thorn – Geometridae – Ennominae – Colotois pennaria – colour code •
STATUS – A resident that is fairly common and widely distributed throughout Derbyshire. Numbers are fairly even north to south and is most common in parks and gardens, where trees and shrubs are abundant.
ID POINTERS – When at rest, this triangular shaped moth holds its wings open and flat. On the wing later in the year than other Thorns and unlike any other autumn flying moth. The tiny white spots near the tip of the forewing are unique to this species. Two horizontal cross-lines through the forewing are usually conspicuous, with the feathered antennae of the male being wider than other Thorns, hence the name.
FLIGHT PERIOD – On the wing September – December.
