Deilus fugax, a species with large area of occurence (Europe except North, North Africa, Near East, Asia Minor), has been described form Provence as Callidium fugax by Guillaume-Antoine Olivier in 1790 [▽]. D. fugax larvae develop under the bark of thin twigs (1-2 cm) of shrubs from the Fabaceae family (Sarothamnus, Cytisus, Spartium etc.). Larvae later enter the wood, where they create pupal cells. The entrance/exit holes larvae clogg by frass. Life cycle from one to three years, the lenght of the development period depends on climatic conditions at the locality. Adults, active from May to July, are diurnal and can be found on the various flowers or beaten from the host plants.
