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

features

The moths reach a wingspan of 26 to 33 millimeters. The forewings are whitish and strongly interspersed with dark scales. Antemedian and post-median lines run more or less parallel to the outer edge of the wing. They are white and serrated, and the antemedian line is more irregular. Both have a dark border towards the midfield. The post-median line is angled towards the Costalader and slightly thickened. The subterminal line is incomplete and less clear. The duplicated discal spots are also indistinct. The outer edge of the wing is white and marked with a series of interconnected, dark moon spots. The fringed scales are dark in the basal half, in the outer half they are white on the outside and darken towards the inside. There is a narrow white line at each end of the wire. The hind wings are whitish and strongly shaded dark brown. The drawing consists of a curved, faintly toothed post-median line and a short dark line in the subterminal region. The first third of the fringed scales are white. The wing undersides are dirty white, with the forewings slightly darker and drawn with an S-shaped white post-median line and a dark discal blotch. On the hind wings there is an evenly curved, dark post-median line with a wide distal white border and a small, faint discal spot.

In the subspecies E. l. poecilalis , the basal, medial and terminal regions are pale bluish gray, speckled with brown scales and speckled black. The antemdian line is white, tinted light brown medially and spotted with black. It is separated from the basal spot and the median line by a strongly serrated black border. Distal to the median line is a fairly wide, white band with serrated margins that darkens distal to a light brown, black speckled area. The sub-terminal line is serrated and interrupted, the terminal line is black and lobed between the wire ends. The discal spot is kidney-shaped and outlined in black, it can be of different degrees. The fringed scales are white and have a broad brown area in the middle, which is interrupted by clear white lines at the ends of the veins. The hind wings are gray-white and tinted light lilac-brown along the veins and towards the outer edge of the wing. The post median line is dentate and incomplete. The terminal line is only indicated. The fringed scales are pale yellow-brown at the base, brown in the middle and white at the top. The underside of the wing is white and, especially in the distal half, very dark yellow-brown to brown. The transverse lines and the discal patch are clearly pronounced.

In the males, the uncus is curved and has a blunt tip with sparse, backward-pointing, hair-like bristles. The shaft of the Gnathos is about twice the diameter of the uncus shaft. The apex is blunt and has a patch of 18 irregular, backward-facing teeth arranged in three rows. The blades are rounded at the base and almost parallel-walled. The tip is beveled and rounded. The aedeagus is rather short and thick and has two elongated cornuti groups lying next to one another and a pair of narrow, brush-like cushions distally .

In females, the corpus bursae is irregularly egg-shaped and has a small sign. The ductus bursae is widened at the junction with the corpus bursae. It also tapers in front of the colliculum .

Similar species

E. l. lupalis is similar to Evergestis sophialis , but has narrower wings and a dark brownish color. The transverse lines on the forewings are straighter and less strongly serrated. The subspecies E. l. poecilalis is unmistakable.

distribution

Evergestis lupalis is native to Spain . The nominate form E. l. lupalis occurs in the Sierra Nevada , whereas the subspecies E. l can be found in the Sierra de Gredos . poecilalis .

biology

The pre-imaginal stages are unknown. The moths fly in July. They are nocturnal and come to light . Resting moths hold the wings flat against the ground, as do, for example, tensioners of the genus Thera .
