Evergestis infirmalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths reach a wingspan of 22 to 26 millimeters, with the females being somewhat stronger and larger than the males. The head and body are gray-brown, the abdomen is weakly banded. The forehead ( frons ) is flat arched. The labial palps are very short. They protrude only a little above the head and are directed downwards. The maxillary palps are clearly visible. The antennae are only ciliated for a very short time. The forewings are pale straw-colored and speckled with dark gray-brown scales. The noticeable features of the drawing are the serrated antemedian line and the S-shaped post-median line, which contrast pale with the speckled background. A dark spot on the Costa loader indicates the beginning of the post-median line. There is a large, dark kidney spot in the pale area of the cell . The fringing area is drawn between the veins with elongated crescent moons. The fringed scales are straw-colored and heavily checked in the basal half. The hind wings are whitish straw-colored and darker on the outside, the post-median line is curved. There is often a small dark spot in the sallow area between the post-median line and the anal angle . The fringed scales are colored in the same way as those of the fore wing. The underside of the wing is whitish straw-colored and darker along the veins. On the underside of the forewing, the discal spot is sharply demarcated, the post-median line and the border line are clearly defined.
In the males the uncus is slightly bulbous and has a tuft of feather-like bristles and a few short, cone-shaped bristles at the apex. The Gnathos is slender, the teeth are only very faintly indicated. The blades are slightly widened at the base and at the top. The costa and the front edge are slightly thickened at the base. The clamp organ (clasper) consists of some stiff, hair-like bristles. The aedeagus is slender, the distal part is prickly and provided with two small groups of cornuti.
In females, the corpus bursae is irregularly spherical. The signa are large and extend over the entire corpus bursae. The bursal duct is wide and slightly constricted. It widens in front of the weakly sclerotized colliculum .
