Host plant.

Ficus carica L. ( Moraceae ).

Remarks.

This species is common wherever there are Ficus carica trees. Larvae, hiding under a thin web, skeletonise mainly young leaves (Figs 19, 20). They have been found in June, and adults have been collected in April–July and September–November, at altitudes from sea level to 1000 m. Choreutis nemorana is only a minor pest on figs in Madeira. The adult flies during day. Male and female genitalia were illustrated by Diakonoff (1986): pl. 66, fig. 81 (male), and pl. 142, fig. 81 (female).

Diagnosis.

The almost square, brown forewings, and the black and yellow hindwings make Choreutis nemorana unmistakeable among Madeiran Lepidoptera (Figs 5, 6).
