The structure of anthophilous longhorn beetles (Col.: Cerambycidae) visiting hawthorns (Crataegus spp.) in the Western Palearctic

The structure of anthophilous longhorn beetles (Col.: Cerambycidae) visiting blossoming hawthorns (Crataegus spp.) in various part of the Western Palearctic was analysed. Field inventories were carried out in Poland, Bulgaria, Italy, Greece, and Georgia. The study started in 2005 and continued with varying intensity until 2014. In total, 458 specimens representing 33 taxa of the Cerambycidae family were collected or observed in the study plots. On blossoming hawthorn shrubs, members of Cerambycinae and Lepturinae subfamilies were most frequently observed. Species diversity of long-horned beetles depends largely on the geographic location and the composition of host plants surrounding the hawthorn shrubs. Some very rare species, e.g. Leptorhabdium caucasicum, Alosterna pauli, A. tabacicolor subvittata, Calchaenesthes oblongomaculatus, and Anaglyptus luteofasciatus have been recorded during the study.
