Evergestis dusmeti is a butterfly from the family of Crambiden ( Crambidae ).

features

The moths have a wingspan of 22 to 26.5 millimeters. The head, labial palps and tegulae contrast whitishly with the dark gray color of the patagia (paired structure on the pronotum that covers the base of the forewings) and the thorax . The front wings are gray-white with a strong earth-brown mixture. They are palest along the inner edge of the wing from the base to the antemedian line. The area between the post-median and sub-terminal lines is speckled blue-gray. The transverse lines run very diagonally. The antemedian line is almost straight, the post-median line is toothed and bulged, and the subterminal line is indistinct, the area distal to it is paler. On the outer edge of the wing there are black dots between the ends of the veins, which more or less form a line that can be extended to around the apex . The fringed scales are pale gray-brown and have a dark subbasal and subterminal band. The hind wings are light gray and slightly shiny. The post median line is indistinct. The black dots between the ends of the veins are more or less fused together, just like on the forewings. The fringed scales are similar to those of the forewings, but the subterminal tape is weaker. The hind wing undersides are light gray-brown, the forewing undersides are darker with the exception of the fringing area. The drawing is only weakly pronounced.

In the males, the uncus is very broad and trough-shaped. It tapers sharply to a sharp point that is concealed by long curved scales. The gnathos has a few small teeth near the tip. The valves are parallel-walled, have a rounded apex and a thickened costa. The clamp organ (clasper) consists of an indistinctly sclerotized bar. The phallus is hardly curved between the basal and distal part. There are two Cornuti groups in the distal section. The first consists of several long cornuti, in the second group the cornuti are numerous, short and bundled. There are also two strong, brush-like areas.

In females, the corpus bursae is very small and hardly wider than the base of the ductus bursae . The Signa are small and far apart. The ductus bursae hardly tapers and widens a little in front of the colliculum .

Similar species

A similar species is Evergestis desertalis (see differences there).

distribution

Evergestis dusmeti is common in southern Spain (including the Tabernas desert in southeastern Andalusia ) and in North Africa ( Morocco ).

biology

The pre-imaginal stages are unknown. Evergestis dusmeti , like the similar species E. desertalis, occurs in stony semi-deserts. The species forms two generations per year in Spain, which fly in May and September. The specimens in North Africa were caught in January and February. The species is nocturnal, both sexes like to come to light .
