Evergestis segetalis
Evergestis segetalis is a butterfly of the family of Crambiden ( Crambidae ).
Features
The moths reach a wingspan of 26-31 millimeters. The front wings are drawn sand yellow and white. Root field, midfield and Saumfeld are heavily speckled with sand yellow scales, so that the oblique white median ante - and post- median lines are irregular and quite wide. At the latter closes distally to a fine, wavy -toothed, interrupted dark line. The Subterminallinie is clearly visible only from the middle of the wing outer edge to the inner angle. The Diskalfleck is indistinct margins brownish. The outer edge is provided between the wing veins with a series of dark points. The fringe scales are white and have a brown base, which is interrupted at the wire ends by white lines. The hind wings are yellowish white and speckled sparsely yellowish brown especially in Saumfeld. The dark Postmedia line is thin and indistinct. On the wing outer edge located between the veins three to four moon spots. The fringe scales are brown in basal half. The hind wing underside is pale yellowish white, the front wing underside is drawn slightly darker and with a pale Postmedia line and an eye-catching dark, slanted seated, rectangular Diskalfleck. The fringe scales are whitish and darker in basal half.
The well-known from Sicily and North Africa subspecies E. s blandalis differs from the Nominatunterart by a lighter and stronger staining and a high-contrast drawing.
In the males, the distal half of the Uncusschafts is crested -like and bears a crest of long, recurved, sickle-shaped bristles. The Gnathos is slightly curved towards the tip and provided with about six widely spaced, short, blunt teeth. The Valven are parallel walls, the apex obliquely rounded and very hairy. Costa is thickened at the base. The clamp member ( Clasper ) is a forward -looking, tongue-shaped, sclerotized lobes. The phallus has a roughened band, the distal part is provided with a dense Cornuti group and a second group significantly greater Cornuti. There is a semicircular group cornutusartiger sting at the base of the brush-like pillows.
In females, the corpus bursae is irregular spherical. The signals are relatively small and short. The ductus bursae is before the Colliculum quite wide, bent and curved.
