Phyllonorycter juncei (Walsingham, 1907)
Lower-surface tentiform mine. The mine has strong, transverse, folds, that cause the tip of the leaflet to strongly curve downwards. Frass concentrated in the distal corner of the mine. Pupation within the mine. As is the rule in the genus, just before ecdysis the pupa works itself halfway out of the mine; unusual is that this mostly happens through the upper epidermis.
Larvae in March and May (Hering, 1957a).
