Phyllonorycter medicaginella (Gerasimov, 1930)

Phyllonorycter medicaginella mines

Melilotus albus, Amstelveen

Phyllonorycter medicaginella mine

Melilotus albus, Nieuwendam

mine

Lower-surface tentiform mine that occupies an entire leaflet. Fully developed mines are strongly inflated and the leaflet is folded so closely that the mine is almost invisible from below. In this stage the larva has eaten all parenchyma above the mine, giving the mine a white colour, and giving the leaflet the resemblance of whitish pod. Th pupa seems to lie free in the cocoon, without a cocoon. In fact the cocoon is part of inner lining of the mine. Frass in a clump in a corner of the mine, separated from the pupa by a partition, (the only recognisable part of the cocoon).
