Additional comments: E. megaspis was reared by Falcoz (1930, Bulletin de la Société entomologique de France (nouvelle Série) 35: [p.150 in] 148-154) from stems of Nasturtium officinale (Brassicaceae). It occurs in all countries around the Mediterranean Sea, was recorded from most of its major islands and also from the Acores, Canary Islands and Madeira. Records from more northern countries (Bulgaria, Romania, Hungary, Czech Republic, Germany, The Netherlands, England, Ireland) are rare. Denmark (in the Pal. Catalogue 1984) was not confirmed by Nartshuk & Andersson 2013 in Fauna ent. scand. 343.
