The Dutch entomologists of EIS Kenniscentrum Insecten report today on recent research about the stony dikes of the Maasvlakte area.
They found two spider species there, new for the Netherlands. They are Theridion hannoniae and Parasteatoda tabulata. Elsewhere in Europe, these spiders live only in rocky areas.
Another Maasvlakte species, new for the Netherlands, is Leiobunum religiosum. This harvestman species lives only in a small part of the Alps, in Luxembourg and Germany.
