Pupation external (unusual for a Chromatomyia).

Germany (Fauna Europaea, 2009); furthermore Switzerland, Slovenia, Bulgaria (Černý & Merz, 2006a; Groschke, 1957a; Maček, 1999a).


The material from which this species was reared turned out two contain two different types of larvae; which of the two relates to vernalis is not known. Both types have been described by Hering (1955a).
