Abstract

Coleophora deauratella Lienig and Zeller is reported for the first time in North America. This casebearer species was introduced accidentally from Europe almost 30 years ago but remained unrecognized. It currently is known from eastern Canada and northeastern United States. Larvae feed on seeds of red clover, Trifolium pratense L. Diagnostic characters of the larval case and the adult, as well as features separating C. deauratella from two similar casebearer species, are presented.

Résumé

L’auteur rapporte pour la première fois la présence de Coleophora deauratella en Amérique du Nord. Cette espèce de porte-case a été accidentellement introduite il y a près de 30 ans mais n’a pas été reconnue auparavant. Elle est maintenant répartie dans l’est du Canada et le nord-est des États-Unis. Les larves se nourrissent des graines de Trèfle rouge, Trifolium pratense L. L’auteur présente les caractères diagnostiques des adultes et des fourreaux larvaires, de même que des caractères permettant de distinguer C. deauratella de deux autres espèces de porte-case similaires.
