Coleophora saxicolella (Duponchel, 1843)

orache case-bearer

on Atriplex, Chenopodium

case

The ultimate case is a trivalved, 6-7 mm long paunchy tubular silken case with a mouth angle of 20°-30°. The larva several times has had to enlarge its case; to this end it then made a slit over the length of the case, then inserted a new strip of silk. The oldest parts are dark and covered with frass grains and detritus, the younger strips are much lighter and clean.

host plants

Amaranthaceae, oligophagous

Atriplex glabriuscula, patula, prostrata; Chenopodium album.

phenology

Larvae in September-October. The full fed larvae leave the host plant for the winter diapause. Pupation in the spring, still in the case.

distribution within Europe

Entire Europe (PESI, 2018).

synonyms

Coleophora benanderi Kanerva, 1941.

notes

The cases cannot reliably be distinguished from those of C. sternipennella, versurella, or vestianella.
