The spotted billy beetle ( Pachytodes cerambyciformis , Syn . : Judolia cerambyciformis ) is a longhorn beetle .
description
The 7 to 11 mm large species is rather stocky for a longhorn beetle. The brown-yellow elytra, which have black spots, are only about twice as long as they are wide and clearly narrowed towards the back. Exceptionally, the spots are completely absent. Forty different spot drawings are known. The species is similar to Pachytodes erraticus . The differences are shown in the table.
Occurrence
The spotted flower buck inhabits large parts of Europe as far as Asia Minor and the Caucasus, but is absent in the north. In Central Europe it is one of the most common species, especially in hilly and mountainous areas.
Way of life
The larva lives on the roots of various hardwood and conifers. It leaves the wood in April or May and pupates in a small cave in the ground. From June to August the beetles can be found, which often stay on flowers.
