Choristoneura hebenstreitella
(Müller, 1764)
The family Tortricidae moth, with a wingspan of 19-30 mm.
Distributed throughout Italy except for Sardinia this rather large Tortricide, it is not very common. It stands out quite easily, in addition,
as already said for the size, the shape and the design of the wings. Presents a slight sexual dimorphism being represented by the size, females,
generally larger than males.
The front wings are earth-colored pale yellowish brown, slightly cross-linked, with light brown markings brown olive scales. The hind wings are dark gray.
The male size of 19 to 25 mm has the front wings with a short rib fold, from the base above the center.
It is pale or yellowish brown ground color,
weakly crosslinked with light brown; olive markings or brown; Basal bands complete with outer edge oblique, slightly sinuous;
the outer edge of the middle band is indented under the coast, the inner edge is usually uninterrupted.
The rear wing is dark gray, fringed clearer (Bradley et al., 1973).
The female size 24-30 mm has the front wings without costal fold, with more pronounced peak.
The grid slightly heavier and the middle band of the front wing is stronger than the male. The rear wing has fringes apical often shades of yellow
Slight variations in the color of the bottom of the front occurs in both sexes and some specimens, especially females,
They have a distinct yellowish appearance. In the markings, the greater variation is located in the middle band, which can be completely broken under the coast.
univoltine these moth is visible during the months of June and July. The eggs are deposited on the leaves of the plant food.
The larvae feed briefly before going into hibernation, completing their development in the following spring.
Wintering larvae occurs within a cocoon. The pupation takes place in late May and June, in the dwelling larvae.
The larvae have a length of 35-40 mm; head dark brown or black; prothorax brown dish, side marked in black, gray abdomen dark green;
black legs; anal area flat yellowish brown. The pupa is brown black; second tergite with two rows of pins.
The larvae feed on the leaves and damage the flowers. Apple, pear and plum are among the host plants, but Choristoneura hebenstreitella
is not considered a significant pest of fruit (Alford, 1984).
Host plants: Corylus, Malus, Prunus, Pyrus, Sambucus, Sorbus, Ulmus,
Quercus), birch (Betula) and willow (Salix), blueberry (Vaccinium) and ivy (Hedera), generally leaves rolled or spun.
note: Dang 1992 believes that Choristoneura adumbratana and Choristoneura hebenstreitella are conspecifics.
