Evergestis politalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths have a wingspan of 20 to 28 millimeters. The head and body are a deep coffee-brown color and only sometimes paler. The drawing is similar to that of Evergestis marionalis , only the inner brown transverse line is often incomplete. The transverse lines are more serrated or notched. In the middle field the veining is purple-brown, in the subterminal field it is highlighted in dark if this is clearly pronounced. The hind wings are darkly shiny, have a distinct narrow outer transverse line and usually a broad, subterminal shadow. A fine, dark hemline is only occasionally visible. The fringed scales are colored just like the subterminal shadow. The undersides of the wings shine and the drawing on the upper sides shimmers through.
The subspecies Evergestis politalis bifascialis ( Guenée , 1849) (= dispersalis ), which occurs in Sicily and North Africa , is larger and the middle field of the forewings is light yellow. The root field and the outer areas are brown, clearly tinted blue-gray and provided with the indistinct markings of typical Evergestis politalis specimens. The hind wings and the undersides are less colored and more filigree than E. politalis .
The uncus tapers and has a blunt tip that is provided with some leaf-like bristles. The Gnathos is 0.3 times as wide as the Uncus and is provided with very small blunt teeth, which are scattered in the distal half. The blades are wide, parallel-walled and have an obliquely rounded apex. The clamp organ (clasper) consists of a weak bulge, adjoined by an area of long bristles directed towards the base. The phallus is slender and on the distal part there is a funnel-shaped opening that contains two groups of three and two cornuti and a pair of small brush-like areas.
In females, the corpus bursae is broad, ovoid and asymmetrical. The signs are very small and are distributed across from the origin of the ductus bursae. The bursal duct has a broad base and tapers. It is rolled up in front of the narrow colliculum .
Similar species
Similar species are Evergestis dumerlei , Evergestis marionalis and Evergestis marocana (see there).
distribution
Evergestis politalis is distributed in southern and central Europe , northern Africa ( Algeria , Morocco , Tunisia ), central Asia , southwest Asia and China . The species is mentioned in the literature for Germany, but there are no specimen copies. The species colonizes suitable habitats from the plain to the low mountain range and can be found on slopes, dry fallow land and on sunny slopes.
biology
The caterpillars live gregariously at the base of various cruciferous vegetables . Smooth-eyed pods ( Biscutella laevigata ) are preferred . The caterpillars feed on the leaves and the base of the stem in August. In central Spain, the caterpillars were also found on Lepidium subulatum between February and April . However, this evidence can also have been Evergestis marocana or Evergestis dumerlei . The species forms at least two generations per year, the moths fly from May to June and from September to October. The moths can be roused during the day and come to light at night .
