Phyllonorycter juncei (Walsingham, 1907)

Lepidoptera, Gracillariidae

mine

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.

hostplants

Fabaceae, oligophagous

Genista maderensis, stenopetala, tenera; Spartium junceum.

phenology

Larvae in March and May (Hering, 1957a).

distribution within Europe

Canary Islands.

notes

On Madeira lives, on the same hostplants, the subspecies Ph. juncei madeirae Deschka, 1976.

Preferance for plants growing in the shade, and for seedlings.
