Teleiopsis diffinis is a butterfly ( moth ) fromthe palm moth family (Gelechiidae).
features
The moths reach a wingspan of 13 to 18 millimeters. The labial palps are blackish and have three to four whitish rings. The forehead is creamy white, the head, thorax and the scales on the wing joint of the mesothorax ( tegulae ) are colored like the forewings. The antennae are ringed blackish and indistinct light brown, in the males they are also ciliated briefly. The forewings have a brownish base color and are whitish, ocher-colored and marbled black, in the first quarter of the wing there is a black band. The middle of the wing is marked with two to three black, ocher-colored spots, two more spots are in front of the indistinctly curved, whitish subapical band. The outer edge of the wing is spotted white and black, the fringed scales have a blackish base and are gray. The hind wings are not marked and are gray. The species is quite variable, with the number of blackish, brownish, ocher, or whitish scales varying from individual to individual. Some specimens have black longitudinal lines on the forewings. In rare cases, a pale pink tint is observed on the light areas of the legs.
Similar species
T. diffinis differs from the similar species Teleiopsis bagriotella and Teleiopsis latisacculus mainly through the band of protruding black scales in the first wing quarter.
Occurrence
T. diffinis is widespread in Europe. There is also evidence from North Africa , as well as from the Middle East and Central Asia . The vertical distribution ranges from the plain to around 2350 meters above sea level.
Way of life
The caterpillars live on the little sorrel ( Rumex acetosella ) and the curled dock ( Rumex crispus ), where they feed on the seeds. The first generation larvae can be found in fine, silky tubular tunnels on the flower stem, where they also pupate . The second generation lives in the feeding tunnels of the stems in the root area of the host plant.
Flight and caterpillar times
Teleiopsis diffinis forms at least two generations a year, which fly from May to August. The larval stage extends from August to April (first generation) and from July to August (second generation).
