Shargacucullia scrophulariae, the water betony, is a moth of the family Noctuidae. It is found throughout Europe, east to Turkey.
C. scrophulariae Cap. (27 h). Not quite so broad as verbasci, the forewing paler and duller in coloration; the dark brown costal streak overlaid with grey and so paler than those on inner margin; the ground colour below median hardly paler, not strikingly whitish; hindwing much as in verbasci.[1] The wingspan is about 45 mm.
The moth flies from May to August depending on the location.
The larvae feed on Scrophularia umbrosa, Scrophularia nodosa, Scrophularia auriculata, Scrophularia canina, Verbascum lychnitis and Verbascum thapsus.
Shargacucullia scrophulariae is difficult to certainly distinguish from these congeners. See Townsend et al.[2]
