Brief description

Phyllonorycter medicaginella (Gerasimov, 1930) is a moth of the family Gracillariidae. It is found from Denmark and Poland to Belgium, the Alps, Bulgaria and Ukraine. The larvae feed on Medicago falcata, Medicago lupulina, Medicago sativa, Melilotus alba, Melilotus officinalis, Ononis spinosa, Trifolium dubium, Trifolium campestre and Trifolium repens. They mine the leaves of their host plant (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Records of Phyllonorycter medicaginella (Gerasimov, 1930) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2024-05-22.

Phyllonorycter medicaginella (Gerasimov, 1930) was first documented by Marcel Hellers on 9 October 2011 at Grousse Mies in Bissen (Hellers 2017: 139).

This species is very rare depending on the year, and then again frequent. It lives on lucerne (Medicago sativa). Here it forms large blister mines on the underside of the leaves. Unlike most other species of this genus, the butterflies hatch in autumn and overwinter as imago. This seems to be a survival strategy of the animals, as the delicate leaves would decay in winter and the caterpillars would have to hibernate unprotected (Hellers 2017: 139-140).
