Ditula angustiorana
Red-barred Tortrix, Fruit-tree Tortrix, Vine Tortrix, Leaf roller
Ditula angustiorana, the red-barred tortrix, is a small tortricid moth with a wingspan of 12–18 mm, characterized by ferruginous ochreous forewings with distinctive deep ferruginous markings. The species is polyphagous, with larvae feeding on a wide range of trees and shrubs including apple, pear, cherry, grape, and various conifers. Unusually among moths, females exhibit calling behavior and pheromone production during daylight hours rather than at night. The species has a single primary brood with adults active from May to August, though occasional second broods occur in autumn.
