Evergestis segetalis is a butterfly from the family Crambidae ( Crambidae ).
features
The moths reach a wingspan of 26 to 31 millimeters. The front wings are drawn sand yellow and white. The root field, middle field and fringing field are heavily speckled with sand-yellow scales, so that the sloping white antemedian and post-median lines are irregular and fairly wide. The latter is followed distally by a fine, undulating, serrated, interrupted dark line. The subterminal line is only clearly visible from the middle of the wing's outer edge to the inner corner . The discal stain has an indistinct brownish border. The outer edge is provided with a series of dark spots between the wing veins . The fringed scales are white and have a brown base, which is interrupted by white lines at the ends of the veins. The hind wings are yellowish white and speckled, especially in the fringing area, sparsely yellowish brown. The dark post median line is thin and indistinct. On the outer edge of the wing there are three to four moonspots between the veins. The fringed scales are brown in the basal half. The underside of the hind wings is pale yellowish white, the underside of the forewings is somewhat darker and marked with a pale post-median line and a conspicuous, dark, oblique, rectangular discal spot . The fringed scales are whitish and darker in the basal half.
The subspecies E. s, known from Sicily and North Africa . blandalis differs from the nominate subspecies in that it is lighter and stronger in color and has a more contrasting pattern .
In the males, the distal half of the uncus shaft is tufted and has a comb of long, recurved, sickle-shaped bristles. The gnathos is slightly bulbous towards the tip and has about six short, blunt teeth that are widely spaced. The valves are parallel-walled, the apex is obliquely rounded and very hairy. The costa is thickened at the base. The clamp organ (clasper) is a forward-facing, tongue-shaped, sclerotized flap. The phallus has a roughened band, the distal part is provided with a dense cornuti group and a second group of significantly larger cornuti. At the base of the brush-like pillow there is a semicircular group of cornutus-like spines.
In females, the corpus bursae is irregularly spherical. The signa are relatively small and short. The ductus bursae is rather broad, kinked and curved in front of the colliculum .
