Evergestis isatidalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths have a wingspan of 28 to 34 millimeters. On the forehead ( frons ) there is a dome-shaped projection. The labial palps are short and directed downwards. The head and body are dark gray-white or brownish white. The fore wing is longer and narrower than that of the other European representatives of the genus Evergestis . The costalader is slightly curved, the apex is pointed and the outer edge of the wing is very sloping. The wings have a straw yellow basic color and are variably brownish or gray-brown speckled. The most noticeable drawing element is a dark kidney flaw near which there is a less obvious round spot. The outer transverse line is curved and slightly S-shaped. It consists of a series of dark points that are located on the veins of the wing. Small black dots are created along the outer edge of the wing between the wire ends. A more or less clear black line on the outer edge of the wing is sometimes extended as an indistinct wavy subterminal line. The fringed scales are monochrome and have two dark lines. The hind wing is relatively broad and, depending on the location, yellowish to white. The outer transverse line is dark and runs parallel to the outer edge of the wing. The interior corner is drawn with a washed-out dark spot. There is a series of black dots between the wire ends. The fringed scales are one color. The fore wing underside is darker than the hind wing underside. Both undersides are drawn with a narrow, dark outer cross line. The fringed scales are hardly spotted.
In the males, the uncus has a blunt tip that is covered with hair-like bristles that are bent back. The gnathos is dagger-like and has five widely spaced apical teeth. The blades are parallel-walled and have a hairy surface. The apex is rounded obliquely and the costa is thickened. The clasper is missing. The phallus is bumpy at the branching point, the distal part is papilla-like and provided with a pair of long, prickly areas.
In females, the corpus bursae is just ovoid and constricted in the middle. The Signa are inconspicuous. The bursal duct is tortuous and tapers abruptly in the middle. The antrum is small and funnel-shaped.
distribution
Evergestis isatidalis occurs in the Canary Islands , on Porto Santo ( Madeira archipelago ), in the Mediterranean region and on Iceland. In North Africa one finds the kind in Morocco and Algeria . In the east it occurs in Turkey , Cyprus and Iran .
biology
The caterpillars develop on woad ( Isatis tinctoria ), in the south of Spain also on field radish ( Raphanus raphanistrum ) and mustard ( Eruca vesicaria ). The caterpillars live on the coast from February to March and in the hill country from April to May. They pupate in an underground cocoon . The moths hatch from December to January. They are nocturnal and come to light .
