  • Razširjenost in biologija vrste Pennisetia bohemica Králíček in Povolný, 1974 (Lepidoptera: Sesiidae) v Sloveniji
    Predovnik, Željko
    The results of a research of the biology of the species Pennisetia bohemica Králíček & Povolný, 1974 in Zaplana near Vrhnika, about 23 km southwest of Ljubljana, are presented. According to Laštůvka ... (2001), P. bohemica has a two year development, which was also confirmed by my finds. The caterpillars can be found throughout the year. They overwinter the first year at a size of (5) 8-12 mm, during the second overwintering they are almost grown up. I found the caterpillars to be locally distributed and always in small numbers but on numerous, mainly sunny, also on partly shaded microlocalities in forests and at their margins, among light bushes in clearings. It is not difficult to find the caterpillars there on various old bushes of field rose (Rosa arvensis Huds.) and to a much lesser extent on an additional unidentified species of the genus Rosa (Rosaceae), where they cause characteristic deformations or swellings on the basal parts of young, one and two year (rarely three year) shoots. Caterpillars were not observed on older strongly woody stems. Thick stems of old bushes, isolated undergrowth and groups of bushes outside continuous woodland, open grasslands, and beside fields, roads and railways were examined unsuccessfully. Many males were attracted to the pheromones (IPO-DLO, Wageningen, The Netherlands). In the same area, we found 11 additional species of Clearwing moths.
