Pachytodes erraticus  is a typical Palaearctic species that is distributed from Spain to East Siberia. It develops under ground in the rotten roots of different deciduous tree species. The pupation occurs in the soil ( Danilevskaya et al. 2009).

This is one of the most common species in the zone of mountains and foothills in northeastern Kazakhstan. We observed this species frequently and rather numerously on the flowers of various Apiaceae  species in different habitats from the roadside vegetation strips in the mountain steppe region through river canyons with Caragana  and Lonicera  (Fig. 15A) to a riverine and mountain mixed forests mainly with Betula  , Populus  , Salix  and Picea  .
