Coleophora amethystinella

I would like to draw attention to some pages and papers showing the occurrence of Coleophora amethystinella.
According to the data on this site, this species occurs in 10 European countries.
According to (Baldizzone & van der Wolf 2007): France, Spain, Portugal, Greece, Great Britain, Macedonia and Italy.
Ignác Richter at coleophoridae.bluefile.cz/: plus Croatia and Albania.
Jan Šumpich and a group of Czech authors at http://www.entomologicalservice.com/files/66_SUMPICH et al 2009_FRC 287.pdf - presents the first entry for Coleophora amethystinella from Central Europe and for Czechia, Brno-Hády. The male caught (16.6.2009, leg., Det., Coll., Ján Liška) is mentioned in this work as synonym of Coleophora fuscicornis.

There is also valuable information on the look and the bionomies on the https://ukmoths.org.uk/species/coleophora-amethystinella page.
It is quite a large Coleophorid, appearing metallic golden green, and has distinctive orange hairs around the eye if viewed closely. It also lacks white on the antennae which helps to separate it from similar species.
The larva feeds on smooth tare Vicia tetrasperma, boring into a seedpod which it uses as aportable case.
Adults fly in sunshine in May/June and can be swept from areas where the foodplant grows.
