Early stages:
Swatschek, 1958, describes chaetotaxy:
Seta L3 present on ninth abdominal segment; V setae not set further apart on ninth than on eighth abdominal segment. Seta SD1 situated equally high as the spiracle on the eighth abdominal segment. Seta V1 is clearly distanced from coxa on metathorax. SV group trisetose on the first, second and seventh abdominal segment, bisetose on the eighth and ninth.
Biology:
There is a single generation yearly; hibernation occurs in the larval stage. Larvae are polyphagous.
Distribution:
Europe to Siberia and Japan; North America.
