Evergestis lupalis
Evergestis lupalis is a butterfly of the family of Crambiden ( Crambidae ).
Features
The moths reach a wingspan of 26-33 millimeters. The forewings are whitish and heavily infiltrated with dark scales. Median Ante - and post- median line running more or less parallel to the wing outer edge. They are white and perforated, the Ante Media line is irregular. Both are margins to midfield towards dark. The Postmedia line is thickened towards angled and easy to Costa loader. The Subterminallinie is incomplete and less clear. The duplicate Diskalflecke are also unclear. The wing outer edge is white and drawn with a series of interconnected, dark moon spots. The fringe scales are in the basal half dark, in the outer half of them are white on the outside and darker inside. Each is a narrow white line on the wire ends. The hind wings are whitish shaded and very dark brown. The drawing consists of a curved, slightly toothed Postmedia line and a short dark line in the Subterminalregion. The first third of Frans dandruff is white. The underwings are dirty white, the front wings are drawn slightly darker and with an S- shaped white Postmedia line and a dark Diskalfleck. On the hind wings there is a smoothly curved, dark post median line, which is distally wide margins white and a little weak Diskalfleck.
The subspecies E. l poecilalis are the basal, medial, and terminal regions pale bluish gray, mottled with brown scales and black spotted. The Antemdianlinie is white, medially light brown tinged 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, which darkens distally to a light brown, black and mottled area. The Subterminallinie is irregularly serrated and interrupted, the terminal is black and lobed between the wire ends. The Diskalfleck is bordered reniform and black, it can vary in strength. The fringe scales are white and have a wide brown area, which is interrupted by distinct white streak at the wire ends into the middle. The hind wings are tinted towards light purple brown gray white and along veins and wing outer edge. The Postmedia line is perforated and incomplete. The terminal line is only indicated. The fringe scales are yellow-brown at the base pale brown in the middle and white at the top. The wing underside is white and obscured especially in the distal half strongly yellow-brown to brown. The transverse lines and the Diskalfleck are pronounced.
In the male the uncus is curved and has a blunt tip with sparse, backward -looking, hair-like bristles. The shaft of the Gnathos has about twice the diameter of the uncus - shaft. The Apex is running too dull and is provided with a patch of 18 irregular, backward -looking teeth that are arranged in three rows. The Valven are roundish and nearly parallel walls at the base. The tip is rounded and beveled runs. The aedeagus is rather short and thick, having two adjacent, elongated Cornuti groups and distally a pair of narrow, brush-like pillows.
In females, the corpus bursae is provided irregularly ovoid and with a little Signum. The ductus bursae is dilated at the junction of the corpus bursae. It also tapers before Colliculum.
Similar Species
EI lupalis similar Evergestis sophialis, but has narrower wings and a dark brownish color. The transverse lines on the fore wings are straight and less strongly serrated. The subspecies E. l poecilalis is unmistakable.
Dissemination
Evergestis lupalis is based in Spain. The nominate EI lupalis occurs in the Sierra Nevada, in the Sierra de Gredos one finds, however, the subspecies E. l poecilalis.
Biology
The preimaginal stages are unknown. The moths fly in July. They are nocturnal and come to light. Resting butterfly keep the wing flat on the ground, as do for example, release of the genus Thera.
