Contribució al coneixement dels lepidòpters del sud de Catalunya. I: Delta de l'Ebre

On the present work is given at know a census of the heterocera of the Delta de l'Ebre (Tarragona), with a total from 117 species. The studied is the recolleted one, year 1984, using eight traps by light of mercury and one trap of Heath's light actinic.En el presente trabajo se da a conocer un censo de los heteróceros del Delta del Ebro (Tarragona), con un total de 117 especies.

Seven species of introduced freshwater snails are found in Barcelona: Potamopyrgus jenkinsi, Radix aff. auricularia, Pseudosuccinea columella, Lymnaea stagnalis, Physella (Haitia) virgata berendti, Planorbella (Seminolina) duryi seminole, and Ferrissia (Pettancylus) wautieri. P. jenkinsi and F. Wautieri are widespread in Europe, the latter being perhaps an autochthonous element. R. all. auricularia clearly belongs to the R. auricularia complex, but differs from other Catalan populations; it has persisted in artificial ponds for almost 70 years. P. columella is a common species in America, has been introduced in many parts of the world, has been reported from several european cities and lives in artificial and semi-natural ponds in Barcelona and Blanes, although later disappeared. P. virgata berendti has a wide distribution in North America and lives in artificial ponds in Barcelona. P. duryi seminole is endemic to Florida but has been introduced, some times deliberately, in many parts of the world; it lives in artificial ponds in Barcelona. P. columella, P. virgata berendti and P. duryi seminole are new for the Catalan and Iberian faunas, and P. virgata berendti is new for Europe. Some of these introduced snails (R. all. auricularia, P. columella and L. stagnalis) could represent health threats, the role of Lymnaeidae as intermediate hosts of fascioliasis being well known
