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

features

The moths reach a wingspan of 28 to 30 millimeters. The species is similar to the western populations of Evergestis frumentalis in size, shape and color. The wings are a bit narrower and the drawing is simpler and more contrasting. The antemedian line is sharply angled and clearer. The post-median line is notched, basad of which run white lines of different lengths.

The shaft of the uncus does not taper in the males . The tip is blunt and somewhat warty. The gnathos tapers to a sharp point and is provided with a series of rearward-facing teeth that extend past the center of the shaft. There the row of teeth widens into a field of significantly smaller teeth. The valves are parallel-walled, the apex is rounded. The clamp organ (clasper) has the shape of a low, triangular sclerotization, which is adjoined by a field with long, stiff bristles. An area with similar bristles borders the front edge of the valves between the clamp organ and the base. The phallus is almost straight and strong. The end is pointed and very warty. In the distal part there are two dense cornuti groups and two brush-shaped areas.

In females, the corpus bursae is irregularly pear-shaped, with the base pointing backwards. The Signa are very large. The bursal duct is narrow and kinked. In front of the long, sclerotized colliculum are two small sclerotized flaps.

distribution

Evergestis pechi is native to North Africa and Jordan . There are also individual records from Malta ( Mriehel 1951, Valetta 1953, Sammut 2003) and from the Spanish provinces of Huelva , Málaga ( Goater 2003) and Almería .

biology

Chrétien found butterflies in the province of Biskra ( Algeria ) and in the governorate of Gafsa ( Tunisia ) from March to May. The caterpillars feed on the flowers and especially on the pods of Sisymbrium irio , Diplotaxis harra and other cruciferous plants . In one clutch, the caterpillars hatched after about ten days and pupated after 23 to 28 days. The egg-shaped, hard cocoon is made of white silk into which sand particles are spun.
