Evergestis subfuscalis is a butterfly from the family of Crambiden ( Crambidae ).
features
The moths reach a wingspan of 28 to 31 millimeters. The head, thorax and abdomen are pale coffee brown. The tegulae are a little grayer. The forewings are somewhat more elongated than in Evergestis aenealis and the outer edge of the wing is slightly concave. The forewings are very pale, light brown in color, they are shiny and have pale, deeply indented and toothed inner and outer transverse lines. The hem band is pale, pale, and toothed. The fringing area is a little darker. The two discal spots are indistinct. The hind wings are unmarked and the fringed scales are evenly colored. The undersides of the wings are whiter and the discal spots on the undersides of the forewings are somewhat more evident. A thin hemline runs at the base of the fringed scales.
The subspecies Evergestis subfuscalis pallidalis , which occurs in Syria, has a lighter basic color. The forewings are light dirty yellow-gray and the hind wings are translucent yellowish gray-white. Cross lines are usually absent.
In the males, the uncus tapers only slightly. It has a blunt tip and is sparsely hairy. The gnathos is weakly toothed. The blades are quite short, parallel-walled and have a rounded tip. The clasper is missing. On the distal part of the phallus, near the base, there is a sloping row of powerful cornuti.
In females, the corpus bursae is irregularly ovoid and wider than it is long. The signa are egg-shaped and are located under the broad base of the ductus bursae . The latter tapers slightly, below the colliculum it narrows abruptly. The antrum is funnel-shaped and slightly fluted.
Similar species
The distinction between Evergestis subfuscalis and the similar species Evergestis mundalis and Evergestis aenealis is described in the respective articles. Another similar species is Evergestis flavifuscalis Rebel , 1903, which is native to Armenia and the Taurus Mountains . In this case, the basic color is strongly mixed brown, the transverse lines run more diagonally and the border area is narrower. The last segment of the labial palps is significantly longer and blunt.
distribution
The nominate form Evergestis subfuscalis subfuscalis is common in Bulgaria , the former Yugoslavia and Greece . In Syria the subspecies E. s. pallidalis .
biology
The pre-imaginal stages are unknown. The species probably forms two generations, the moths fly in summer.
