Entomological collections Dytiscus latissimus

The giant diving beetle inhabits lakes and ponds of northern and central Europe. It is a rare species, vulnerable and protected, surely extinct in several European countries and possibly in others as well. In Italy it has been documented only twice, over a century ago, in the surroundings of Vicenza and Venice respectively. One of these precious specimens, collected around 1900 by Giacomo Bisacco Palazzi in Mirano (Venice), is preserved at the Museum of Natural History of Venice.
