Eteobalea anonymous ella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).
features
The moths reach a wingspan of 8 to 15 millimeters. The head is yellowish white and on the sides and back ocher to light brown. The antennae are dark brown and have five white rings at the tip. The thorax has a dark brown sheen and some lighter spots behind. The legs are dark brown. The forewings have a dark brown sheen and three white costal spots: The first is 1/6 of the forewing length. It is elongated to a pale gold-colored line that runs obliquely outwards, which extends beyond the anal fold, but does not reach the inner edge of the wing. The second is located in front of the middle of the wing and is extended to a raised, pale gold line. It points slightly outwards and ends in the middle of the wing. The third is at 3/4 of the forewing length and is more than twice the size of the two inner spots. Below it is connected with a small, raised, pale gold spot. There are two more raised, pale gold spots on the inner edge of the wing. The inner one lies opposite the second costal spot and the outer one is perpendicular to the inner edge of the wing and is a little further inward than the third costal spot. There is also a raised, pale gold spot on the apex . A series of small, raised, pale gold lines are - mainly dorsally - on the outer edge of the wing. The hind wings have a light gray sheen and are darker towards the apex. The abdomen has a brown dorsal shine.
In the male, the tegumen narrows at the back and has a V-shaped indentation. The right brachium is almost straight and twice as long as the left. The tip is only slightly widened. The left brachium has a blunt tip. The blades are pear-shaped. The right valvella tapers slightly distally and has a rounded tip. The aedeagus is slightly curved. The bulbous part is oval, the tubular part narrows distally and has a pointed apex.
In females, the 8th segment is as long as it is wide. The ostium is circular. The sterigma is spherical. The ductus bursae is as long as the corpus bursae . The corpus bursae is short and oval and tapers abruptly at the back. There are two sickle-shaped signs of different sizes.
Similar species
Eteobalea anonymella is similar to Eteobalea serratella , but differs from this species by the smaller wingspan, the more silvery drawing elements on the front wings and the dark brown femura of the hind legs.
distribution
Eteobalea anonymella is widespread in Europe with the exception of northern Fennoscandinavia . The species is also found in North Africa , Asia Minor , the Near and Middle East, and east in Iran and Central Asia . In the south the species is restricted to mountainous regions.
biology
The biology of the species is unknown. The moths can be found from May to mid-August. Presumably there is a second generation from late August to early September.
