Pristerognatha fuligana: opened gall

opened gall with larva

gall

The larva lives in a low part of the hollow stem, causing a clear swelling. The larva closes the space above by making out of silk and frass a few septums. Pupation in the stem.

host plants

Balsaminaceae, monophagous

Impatiens glandulifera, noli-tangere.

distribution within Europe

(PESI, 2019).

larva, pop

Pictures on Lepiforum; also Patočka & Turčáni, Swatschek.

synonyms

Endothenia, Olethreutes, fuligana.

notes

It is not quite clear whether the swellings of the stems really are caused by the larvae. According to some botanical sources they are characteristic for older plants. In I. glandulifera, a amuch coarser plant with a thicker stem, the larva doesn’t cause swellings (observation Ruben Meert).
