Eteobalea serratella is a butterfly ( moth ) from the family of cosmopterigidae (Cosmopterigidae).

features

The moths reach a wingspan of 13 to 19 millimeters. Eteobalea serratella is similar to Eteobalea anonymella , but differs in its larger wingspan, the more conspicuous pale gold drawing with a bronze sheen on the thorax , tegulae and forewings, the white femura of the hind legs and the ocher-colored first four segments of the abdomen .

In the male, the tegumen is rather narrow and almost parallel- walled . The bulge is U-shaped. The right brachium is curved and about twice as long as the left. The tip is rounded and widened and heavily sclerotized . The left brachium has a blunt tip. The blades are concave to boot-shaped. The cucullus is slightly rounded. The right valvella is large. It is thickest in the middle and tapers to a blunt point. The aedeagus is slightly curved and has a slender bulbous part. The tubular part is very wide and gradually tapers to a sharp point.

In females, the 8th segment is longer than it is wide. The ostium is circular. The sterigma is sack-shaped and has a sclerotized transverse ridge in the middle. The ductus bursae is less than half as long as the corpus bursae. The corpus bursae is elongated and clearly widens behind. The signa are very small or absent.

distribution

Eteobalea serratella is widespread in Europe. The distribution area includes Spain , Portugal and France in the west and extends over the Mediterranean and Central Europe to the southeast of the European part of Russia. The species is absent in Northern Europe and the British Isles . In the east, the species is also found in Asia Minor , the Middle East and Central Asia .

biology

The caterpillars develop on real toadflax ( Linaria vulgaris ) and on the subspecies Linaria genistifolia euxina of the gorse toadflax . Evidence of the snapdragon ( Antirrhinum majus ) requires verification. The females lay the eggs individually on the lower sections of the stem. From there, the caterpillars mine down into the main root. In the last stage of the caterpillar, they return to the lower section of the stem and finally pupate in the root neck or in the base of the stem. The caterpillar stage lasts about eleven months. The species forms one generation a year. The moths fly from late June to early September, according to another source from May to June.

In the United States were eteobalea serratella - populations tentatively for the biological control of Genuine toadflax in the cultivation of peppermint ( Mentha x piperita ) used. In the presence of Eteobalea serratella, the tests showed a 17 percent higher yield of dried mint shoots. Although some field tests have been carried out, no established populations have been detected in the field.
