The 6 to 9 mm large checkered beetle Tillus elongatus (family Cleridae) is the only representative of the genus Tillus in our fauna. The subfamily Tillinae comprises about 550 species worldwide, they are most diverse in the epiequatorial Neotropics. Tillus elongatus shows a marked sexual dimorphism: While the male is all black, the female is slightly larger and exhibits a red pronotum. The thermophilous species occurs in Europe including the British Isles to the Caucasus and lives in old deciduous and mixed forests and parks. Its larvae prey on the development stages of other wood dwelling insects, in particular the Fan-bearing Wood-borer Ptilinus pectinicornis. In Germany, Tillus elongates is widespread and recorded from all Federal States, but not everywhere common. It is regarded as vulnerable (RL 3). (CB)
