D i s t r i b u t i o n. Very widespread, North Europe: Denmark, Sweden, Norway, Scotland, Ireland, Finland to Siberia. South Europe: Italy, Spain, France. North Africa. Middle East: Turkey, Iran: Rozkošný (1987); Seddighi Sadr, Mohammadzade Namin (2016).
Biology. The complete life cycle has been realized in laboratory by Vala (1986) who described all the immature stages. If adult emerge from mid-April no matting is observed before August, due to a long pre-oviposition period, and flies are collected until early November (Vala, 1986). In laboratory, larvae attacked and fed the terrestrial gastropods Candidula unifasciata (Poiret, 1801), Cornu aspersum (Müller, 1774), Lauria cylindracea (Costa, 1778) and Trochulus hispidus (Linnaeus, 1758) (Vala, 1986, Gaponov, 2016). With the viviparous L. cylindracea, the first-instar larvae of T. punctulata fed firstly the young snails located in the pallial cavity of the mother host (Vala, 1986). Then, they fed the later before to leave the shell, and the second and third instar larvae attack larger snails (Vala, 1986). Puparia are mostly formed inside the host snail´s shell. The species is univoltine and overwintering as pupa (Vala, 1986; Gaponov, 2016).
