Ascalenia viviparella is a butterfly ( moth ) fromthe Chrysopeleiidae family .
features
The moths reach a wingspan of 7 to 10 millimeters. The head, thorax and tegulae shine gray-brown, the scales here have light-colored tips. The feelers shine gray. The forewings are gray-brown and speckled with light gray scales at the tips. An indistinct and irregular subcostal line extends from the base of the wing to 1/3 the length of the forewing. It is partially curved in the direction of the anal fold, crosses it in the middle, but does not extend to the inner edge of the wing. Another subcostal line is at half the fore wing length. An irregular, zigzag-shaped, light gray band is 3/4 of the fore wing length. The apical area of the forewing is more light gray in color, the fringed scales shine light gray. The hind wings also shine light gray. The females have some large, dark gray scales on the inner corner of the underside of the forewing. The hind wings are provided with a series of large, dark gray scales in the middle of the dorsal area. The abdomen has a light gray sheen, in females segments six and seven are laterally and ventrally blackish. The drawing of the forewings is very variable, the lines and bands like the light speckles can be more or less pronounced, so that it can be confused with other, similar species.
In the males the uncus is long and strong. It has a blunt, hook-shaped tip. The blades are long and taper slightly in the distal half. The notch on the apex is surrounded on the outside by a heavily sclerotized ring, inside there are coarse bristles of different lengths. Two large and strongly curved bristles are located at the base. The aedeagus is long and slender. It is curved in front of the middle and has two short spikes of different lengths. The first is located dorsolaterally in the middle. The second is smaller and is located at the apex.
In females, the slit-shaped bulge of the seventh sternite is U-shaped, the posterior half is sclerotized. The fold of the sixth sternite is large and trapezoidal. The ostium is wide and round, it is surrounded by two large side shields with a reticulate structure. They taper in the middle and are bent outwards at an acute angle. The ductus bursae is short and wide, it runs in several turns. A sclerotized longitudinal ligament runs in the middle, which is particularly pronounced in the direction of the ostium. The corpus bursae is egg-shaped and has two small, often two-pointed signs.
distribution
Ascalenia viviparella is native to most of the most south-eastern areas of Europe ( Crimea , south of the Urals ). The species is also found in Afghanistan , Iran , the Ukraine , southern Russia, Asia Minor , the Transcaucasus and Central Asia in the east as far as Mongolia . The species is common in deserts and semi-deserts .
biology
The caterpillars develop on Calligonum junceum , Calligonum setosum and Calligonum leucocladum . They live on the shoots and fruits of the host plants from late spring to the second half of summer. The species forms two generations a year, the moths can be found throughout the year. They overwinter in the burrows of various rodents.
