Leptura quadrifasciata
Leptura quadrifasciata, the four-banded longhorn beetle, is a species of beetle in the family Cerambycidae. It is found throughout the northern and central Palaearctic region. The species is distributed in northern and central regions of Europe and Asia. It is particularly common in Scandinavia, Finland and Great Britain, and typically seen during the summer months. The larvae make meandering galleries in various trees, including oak, beech, birch, willow, alder, elder and spruce – typically in dead and decaying wood, with a preference for damp areas. Adult beetles are 11 to 20 millimetres (0.43 to 0.79 in) long, black with four more or less continuous transverse yellow bands. In extreme cases the elytra may be almost entirely black. The life cycle of the species lasts two or three years. This L. quadrifasciata female was photographed on wild carrot flowers near Keila, Estonia.Photograph credit: Ivar Leidus
