Plant Parasites of Europe

leafminers, galls and fungi

Coleophora silenella

Coleophora silenella Herrich-Schäffer, 1855

on Silene

Coleophora silenella: case

case on Silene nutans (from Patzak, 1986a)

parasite

The young larva lives in the capsules, feeding on the developing seeds, without any visible sign at the outside. Only in its latest instar it bites from the inside a hole in the wall of the capsule, the closes it wich much elastic silk. By continuous pushing against the silk this is pulled into a tube, that will form the definite tube (more in Emmet ao). This is a dark greyish brown, 8 mm long, trivalved tube with a mouth angle of ± 40°. From this case holes are bitten in the walls of new capsules and the contents devored.

hostplants

Caryophyllaceae, monophagous

Silene italica, nutans, otites, vulgaris.

phenology

Larvae in cases around August. The larvae are full fed in September and leave the host plant.

distribution within Europe

Missing from Scandinavia, Ireland, Greece, the Mediterranean Islands and perhaps the Iberian Peninsula (PESI, 2018).

synonyms

The moth has in the past been confused with Coleophora ciconiella Zeller, 1849, that lives on grasses. Also with C. nutantella is the species closely related; Patzak (1976a) discusses the few differences. Emmet ao have synonymised silenella and nutantella, but this turned out incorrectly.
