Eteobalea intermediella
Eteobalea intermediately ella
Eteobalea intermediately ella is a butterfly (moth ) from the family of the splendor butterfly ( Cosmopterigidae ).
Features
The moths reach a wingspan of 11-17 millimeters. The front wings are slightly narrower towards the apex. The drawing resembles Eteobalea serratella, but it lacks the pale golden spot underneath the third white Costalflecks.
The males have a long Tegumen, the rear tapers slightly and has a rounded bulge. The right brachium is slightly curved and about three times as long as the left. The tip is rounded and widened strongly sclerotized. The left brachium has a square Apex. The Valven are concave and have a rounded cucullus. The right Valve is parallel-walled, tapering to a blunt tip. The aedeagus is rather slender and curved, the tubular portion tapers sharply to a sharp point. The genital armature of the males differs from Eteobalea beata and Eteobalea sumptuosella by the widened and rounded sclerotized tip of the right Brachiums and the slender aedeagus with a wide tubular portion and the large, pointed Anellus arm.
In females, the 8th segment is about as long as wide. The orifice is a semi-circle or oval. The sterigma narrows distally. The ductus bursae is slightly shorter than the corpus bursae is long. The corpus bursae is elongate and the front of the widest. It tapers slightly to the rear and has two differently sized, crescent-shaped signals.
Similar Species
Eteobalea intermediately ella similar Eteobalea beata and Eteobalea sumptuosella very strong, differs from these species but by the third Costalfleck. It is smaller, more square inside concave and outwardly convex. A reliable species identification is possible only by a genital examination.
Dissemination
Eteobalea intermediately ella is in central and southern Europe, common in the Caucasus, Asia Minor, the Near and Middle East and Central Asia. The species also occurs in Algeria and Morocco.
Biology
The caterpillars develop on Genuine toadflax ( Linaria vulgaris), Linaria pontica, broom toadflax ( Linaria genistifolia ), Dalmatian toadflax ( Linaria dalmatica ) and hole gullet ( Anarrhinum bellidifolium ). The females lay eggs in groups on the lower portion of the stem and the caterpillars burrow from there to the main root. They often live socially and eat both the root cortex and in the nucleus. The number of beads per root is the diameter of the root -dependent.
The caterpillars eat the last stage, however, again in the lower regions of the stem, while a number of shoots is clearly visible damage. The caterpillars pupate in the stem base or in the upper part of the root. The preimaginal stages are those of Eteobalea serratella very similar, differences were found only in the structure of the egg membrane. It makes two generations per year in the north and in the east of its range there is only a generation. The moths fly from early May to early November.
