The Ditula angustiorana is a moth of the Tortricidae family, subfamily Tortricinae,
with wingspan of about 12-18 mm.
In Europe we find it in the Iberian Peninsula, in the United Kingdom, in Ireland, in the Benelux, in Denmark, in Sweden and in Poland. *
In Italy it is also present in Sardinia. *
The front wings of the Ditula angustiorana are rust / ocher in color. In the male base and costal fold are dark brown.
There is a ferruginous-brown oblique mark from the back near the base.
The central band and the rib patch are of an intense rusty orange color, often separated by a whitish suffusion on the coast, and the patch extends like a band at the tornus. **, ****
The hind wings are gray-black, in the female lighter in front. ****
Sexual dimorphism is represented by the absence, in the female, of the large ocher spot in the median area. **
Univoltine species, adults are visible from May to August depending on the latitude, occasionally a second generation has been found in September, October.
The eggs are deposited in plaques on the leaves mainly in June and July. ***
The larvae are found from August to April and May and are polyphagous, they feed on the foliage of the trees, generally between spun leaves and fruiting shoots developing; sometimes causing superficial damage to ripe fruit. ***
In late autumn, the larvae create a hibernacle attached to a bud or spur and resume feeding on developing buds, flowers and fruit in the spring. ***
The eggs are whitish / light yellow, flat and irregular in shape. **, ***
The larva of the Ditula angustiorana is yellowish green, with a darker ocher to brown / black head and prothoracic shield. **
The chrysalis is light brown with darker shades. **
