Euura scotaspis galls

Salix viminalis, Millingerwaard

Euura scotaspis gall

detail

gall

The solitary larva lives in the downwards rolled leaf margin, that has become a narrow tube. Only on the base of the larva the gall can be distinguished from those of E. anglica or piliserra; the identification of the pictures above therefore is not certain!

host plants

Salicaceae, narrowly monophagous

Salix viminalis.

According to Beneš (2015a) also S. gmelinii and schwerinii.

larva

Third abdominal segment with 4 dorsal annulets; 1–3 with setae. Suranal plate with widely separated, small, pseudocerci, but without black markings.

synonyms

Phyllocolpa, Pontania, scotaspis.

note

Member of the Euura oblita species group.
