Biology and notes: This species is an inquiline in the galls of Jaapiella floriperda on Silene spp. ( Caryophyllaceae). All our records are from S. vulgaris . Bi- or multivoltine. Pupation and hibernation in the soil. The larvae are distinguished from those of the host by being white rather than yellowish to red. This is not always a reliable distinguishing trait, as immature larvae of the host may also be white. We DNA barcoded one pink and three white larvae from three different samples and found that the pink and the white larvae were indeed different species. One sample (Vågå, Fellese) contained both species, while the two others contained only white larvae which then can be referred to Jaapiella inflatae .

Distribution: Only known from UK, Germany, Latvia and Norway.
