features

The wings of the females are shorter and wider than those of the males and have a more blunt wing tip. The moths reach a wingspan of 29 to 34 millimeters for the females and 33 to 41 millimeters for the males. The head, thorax and abdomen are speckled dark brown and gray. The main veins of the wings are paler. The gray-white subbasal line is very indistinct. It is curved and sloping. The Antemedian, Postmedian, and Subterminal lines are white and very clear. The first named is strongly serrated in the cell and then runs almost straight and diagonally to the inner edge of the wing. The post median line is S-shaped and curved outward on the inner wing of the wing. The subterminal line is slightly booked out. The fine hemline is interrupted by the pale ends of the wing veins . The fringed scales are strongly piebald. The wing veins stand out darkly on the brown hind wings. The post-median line is noticeably gray, with dark wedges extending into it from the basal side . There is a dark spot in the anal corner. The hemline is blackish and the fringed scales are pied as well as on the forewings. The hind wing undersides are light gray-brown and not shiny. There is a dark discal spot on the underside of the forewing , the ante-median and post-median lines are indicated pale.

The drawing of the females is similar to that of the males, but it is usually darker and more contrasting. The hind wings are darker and have a more contrasting, sallow post-median line.

In females, the entire genital armature is unusually heavily sclerotized . The uncus is strong and slightly hairy. At the apex there are sickle-shaped, hair-like bristles. The gnathos is quite short and blunt. It has a few short, blunt teeth at the apex. The blades are short and thick and have a rounded apex. A saccule is formed at the base . The clasper is missing. The branching point of the phallus is bumpy. The tip is papillary, on the distal part there are two cornuti groups and a scaly, brush-like area.

In females, the corpus bursae is obovoid (inverted ovoid). The ductus bursae is constricted before and after the confluence of the ductus seminalis. The antrum is broadly funnel-shaped.

Similar species

E. umbrosalis is similar to Evergestis serratalis . The latter species is smaller and does not show any sexual dimorphism . The similar species shows a centrally darkened post-median line and a dark, pale (almost white) edged subterminal line on the forewings. The fore wing undersides are darker than the hind wing undersides. They are provided with a dark, pale postmedian line. The fringed scales are pied. There is a faint dark post-median line on the undersides of the hind wings. The fringed scales are only very weakly piebald.

distribution

Evergestis umbrosalis is native to Greece, Spain, Ukraine , the European part of Russia and Turkey . According to older sources, the species was also found in Jordan and Lebanon .

biology

The pre-imaginal stages are unknown. In Turkey Falter early May were caught in the Sierra Nevada in Spain in early July.
