View of the 2018 sampling location (small pond) where Leptogromia operculata was found.

Schiermonnikoog

This island between the North Sea and the Waddensea is largely a nature reserve. It is partly fled by the sea and therefore the water is brackish. I collected material in 2011 and 2018 at two different sites, indicated below on the map.
