Occurrence
The species occurs in North Africa and Europe, north to Denmark. It colonizes dry and temperature-favored habitats with sandy soil, such as sand pits, forest edges or ruderal areas. The animals fly from mid-April to mid-September. The species is rare to widespread in Central Europe.
Way of life
The females of Alysson spinosus lay their nests on sunlit sand, but also gravel. The main corridor is initially flat and then leads vertically to presumably a single cell. The females are only active on certain warm days in the morning and at noon. The brood is supplied with cicadas, which are grabbed between the mandibles and flown to.
