The northernmost known observation of Myrmecophilus acervorum and the first records of Myrmecophilidae (Orthoptera, Ensifera) from Latvia

Abstract

The first observations of myrmecophilous ant cricket Myrmecophilus acervorum (Panzer, 1799) and the family Myrmecophilidae from Latvia are presented. The observations were made in two locations subject to flooding in springtime. Adult and juvenile female individuals were observed. The discussed records appear to be the northernmost known distribution limit of this species.
