Evergestis serratalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths reach a wingspan of 27 to 33 millimeters. The forewings have a light earth-brown color with a fine dark brown mixture. The root field has a very sloping white border and contains spots within the cell that consist of black scales. The antemedian line is white, thin and strongly tooth-shaped in the cell. Towards the inner edge of the wing it runs very diagonally. The black post-median line runs parallel to the wing's outer edge. It is slightly wavy and has a wide white border on both sides. A row of black, arrow-shaped spots is located in the middle fringe area in the vein spaces. The hemline is black and very thin. The middle field is extensively black, the main veins are highlighted in white. The fringed scales are gray-brown, with the basal half being darker. There are white lines in the spaces between the ends of the wires. The hind wing tops are dirty white and have a dark outer shadow. The white post median line and the thin, black border line are curved and only faintly indicated. The fringed scales are light gray, the basal half is darker. The wing undersides are gray-white and darker on the fore wings and in the outer half of the hind wings. The discal spot on the forewings is black. The females are slightly smaller and more compact than the males.
In the males the uncus shaft is parallel- walled and quite hairy. The apex is rounded. The gnathos has a blunt tip with six short, irregularly shaped teeth. The valves are strongly tapered, the costa is thickened and the apex is rounded. The inner surface is very hairy, a clasper is not clearly formed. On the distal part of the phallus there are two juxtaposed groups of strong, curved cornuti and a pair of large, scaly ridges.
In females, the corpus bursae is egg-shaped and hardly wider than the basal part of the ductus. The signs are wide. The ductus bursae is very wide and tapers to the point of constriction just before the colliculum .
Similar species
The species is unmistakable due to the white highlighted veins and the wide, white-edged post-median line on the upper side of the forewing.
distribution
Evergestis serratalis occurs on the Balkan Peninsula and the Crimea .
biology
The pre-imaginal stages are unknown. The moths fly between bushes and in open deciduous forests in September. They are nocturnal and like to come out into the light .
