Pelatea klugiana is a small butterfly of the family of Winder (Tortricidae). The caterpillars of the species live exclusively on species of the genus peonies ( Paeonia ).

features

The moths have a forewing length of 10.0 to 10.7 millimeters (nominate subspecies), the verucha subspecies is on average somewhat smaller with 9.0 to 9.3 millimeters. The wingspan is given as 22 millimeters. There is no costal fold, the costal edge is slightly curved. The basic color of the forewings is light olive-brown or yellowish olive-green in the proximal half, the Kostalrand is somewhat darker. The distal wing half is pink or brown-red. This area is covered by an indistinct, silver-colored, net-like pattern. The discal spots are dark brown in color and often broadened into a curved cross-band. The fringes are colored light red-brown. The hind wings are also light olive brown, but have a narrow, darker outer field. The fringes are kept in the basic color. The head and body are colored dark brown, the tegulae are provided with a tuft of red-brown scales . The metathorax has two red tufts of scales, the back of the back of the body is covered with yellow-red hair and therefore appears lighter brown. Slight sexual dimorphism is observed. The females are on average slightly larger and more robust. The silver-colored mesh on the outer field is more indistinct, the hind wings dark gray.

The adult caterpillar is 10 millimeters long and has a diameter of max. 2.5 millimeters. It tapers significantly towards the front end. The head is black, the body dark green and without any markings. The long bristles are elastic and gray in color.

The pupa is 7.0 to 10.5 millimeters long and dark yellow-brown in color. The forehead is flat and smooth. The proboscis sheath extends to about a third of the wing length. The Kremaster is wrinkled on the belly. The cremaster end is covered with four pairs of hook-like curved bristles.

Geographical distribution and habitat

The species is widespread in southern Europe, but little has been proven so far. You can find it wherever peonies occur naturally. The area extends from the Iberian Peninsula in the west, across southern France ( Alpes-Maritimes department ), Italy , Austria , Slovenia , Hungary , Croatia ( Istria ), Bulgaria , Romania to the Ukraine and southern Russia . In the north the distribution area extends to Lower Austria and Carinthia ; in Germany the species has not yet been identified.

The species is mostly limited to the hilly and mountainous areas of distribution. It occurs almost exclusively on chalky soils, because the peony species prefer to grow on chalky soils on open slopes or in open, sparse forests. The subspecies Pelatea klugiana verucha , on the other hand, is more widespread in the lowlands (approx. 150 m above sea level), but also occurs on limestone soils. It is not known to which subspecies the evidence in Ukraine belongs.

Way of life

The species forms one generation a year, the moths of which fly from May to June (June to July). The moths are not very active and usually sit around near the host plant. They only live a few days. The caterpillars live in small colonies of two to five specimens (or up to seven specimens). They weave young shoots of the host plant into a web. They eat and move in web tunnels without leaving the web. The following peony species (Paeoniaceae) are mentioned in the literature as host plants:

The hibernation stage is not yet known with certainty, presumably it is the egg, the caterpillars in the egg shell or the young caterpillar. The caterpillars pupate in the web. Shortly before they hatch, the pupae slide out of the web.

Taxonomy

The taxon was first scientifically described in 1834 by Christian Friedrich Freyer as Tortrix klugiana . It was later determined to be a type of the genus Pelatea Guenée, in 1845.

There are currently two subspecies :

  • Pelatea klugiana klugiana ( Freyer , 1834) - the nominate subspecies
  • Pelatea klugiana verucha Nedoshivina & Zolotuhin , 2005 - Southern Russia, a little lighter in the basic color, on average a little smaller
