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

features

The moths reach a wingspan of 27 to 28 millimeters. The head is ocher, the thorax is light ocher. The front wing has the contour typical of the genus Evergestis and has a whitish basic color. It is variably speckled with ocher and dark scales. In the case of paler specimens, the speckling is usually more or less limited to the costal area and the subterminal area. The whitish subbasal, antemedian, and postmedian lines are wavy or toothed. They are bordered by some dark scales and are usually quite indistinct. The two discal spots are indistinct and darkly edged. There are blackish spots between the ends of the veins. The fringed scales are whitish straw-colored. They are yellow at the base and have two rather broad ocher lines. The hind wings are dirty white and drawn with a very indistinct ocher post-median line and a shadow on the outer edge. The fringed scales are colored like those of the forewings, but they lack the outer dark line. The underside is shiny and has an indistinct pattern that corresponds to that of the top. The abdomen is ocher in color.

In the males, the shaft of the uncus is slender and slightly hairy. The tip is blunt and has a few short, bent back hairs. The Gnathos has a deep trough-shaped shape. It tapers and has a narrow tip. A row of small, occasionally standing, blunt teeth extends from the apex to about half of the shaft. The edges of the blades are slightly wavy, the apex is rounded at an angle. The costa and the front edge are thickened mainly at the base. The clasper is clearly visible. The phallus is bulbous and provided in the distal part with two small, closely spaced cornuti groups and scaly, brush-like cushions.

In females, the corpus bursae is egg-shaped and hardly wider than the base of the ductus bursae . The Signa are small. The ductus bursae is wide and tapers evenly to a narrowing behind the only slightly sclerotized colliculum .
