Evergestis desertalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths reach a wingspan of 26 to 30 millimeters. The head, labial palps and patagia (paired structure on the pronotum that covers the base of the fore wings) are colored in the same way as the thorax . The forewings are whitish, faded, leather-brown in color. The antemedian line has a strong tooth in the cell , after which it runs very obliquely to the inner edge of the wing. The post median line is slightly curved. It begins near the apex and runs obliquely to the inner edge of the wing. It is black and shaded paler towards the base. The subterminal line consists of a broken series of black spots. The hemline is very thin and black. The fringed scales are whitish and divided by two dark lines. The hind wings are gray and darker towards the outer edge of the wing. The dark post median line is incomplete, the hem line is thin and black. The fringed scales are divided by a dark line. The basal half is leather brown, the distal half is white. The hind wing undersides are gray and darker along the veins. The post-median line is indicated dark on all wing undersides.
In the males, the uncus is parallel- walled and somewhat thicker towards the tip. It has a few long, stiff bristles. The Gnathos tapers cylindrically and has a row of about twelve small, flat teeth. The blades have a broad base and taper to an obliquely rounded apex. The clamp organ (clasper) has the shape of a conspicuously sclerotized lens-shaped rod. There are stiff, hair-like bristles on this rod and immediately next to it. The phallus is strong, on the distal part there are two unequal groups of cornuti and a pair of brush-like areas.
In females, the corpus bursae is almost egg-shaped and separated from the base of the ductus bursae . The Signa are medium in size. The ductus bursae is moderately wide and hardly tapers. In front of the colliculum there is a lateral protuberance.
Similar species
The similar species Evergestis dusmeti has a similar appearance, but is more brownish and less clearly marked. The head, labial palps and patagia are whitish. The wings are slightly wider and have a more rounded apex . The antemedian line is almost straight. Other similar species are Evergestis plumbofascialis and Evergestis aegypticalis .
distribution
Evergestis desertalis is found in the Canary Islands , Spain , Sicily , Malta , Romania, Bulgaria and North Africa. Further to the east, the distribution area also includes the European part of Russia, Ukraine , the Arabian Peninsula and Iran .
biology
The pre-imaginal stages are unknown. The species forms two or more generations per year and inhabits stony semi-deserts. The moths fly from May to October and come to light .
