'' Monochroa servella'' is a moth of the Gelechiidae family. It is found from Fennoscandia to Italy and from Portugal to Bulgaria and Russia. The wingspan is 11–13 mm. Adults are on wing in June.〔(Swedish Moths )〕 The larvae feed on ''Primula farinosa'' and ''Primula veris''. They mine the leaves of their host plant. The mine has the form of a large, transparent, full depth blotch that starts in the basal part of the leaf. Most frass is deposited in the first part of the mine. The mine is strongly folded lengthwise. Full-grown larvae leave the mine to pupate. They attach the pupa to the apical part of a fresh leave.〔(bladmineerders.nl )〕 Larvae can be found in May. They are dark red, mottled with greyish white.
