New winter stonefly species in the Netherlands

Wednesday, March 31, 2010

Researchers from the Stichting European Invertebrate Survey (EIS Netherlands) and Naturhistorisk Museum in Oslo (Norway) have found a new winter stonefly species in the Netherlands. They discovered a shedded skin and an adult animal in the Roer river in St. Odiliënberg.

It is the first find of this particular insect, the stonefly Taeniopteryx schoenemundi, in the Netherlands and one of the few recent observations in Western Europe. Water quality in the Roer has greatly improved in recent years and more and more special insects such as dragonflies and caddis flies have been found. Yet the discovery of these winter stoneflies is a big surprise because this species is historically unprecedented in the Netherlands. The stonefly, which has a preference for cold, oxygenated water, may have benefited from the relatively recent severe winters. …

The species belongs to the family of winter stoneflies, an exceptional group of winter active insects. Plecoptera are slender, long-winged insects whose larvae live in clean streams and rivers. They are considered to be important indicators of water quality. Previously there were 27 species of stoneflies in the Netherlands, but because of pollution no less than 17 species disappeared. Plecoptera are among the most endangered animals in the Netherlands.

ScienceDaily (Apr. 4, 2011) — Loss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a study recently released in Climatic Change Letters: here.

  1. 600.000 soorten insecten naar Naturalis

    vandaag 18:49

    LEIDEN – Ruim 600.000 soorten torren, kevers, wespen, motten en andere insecten verhuizen deze week van Wageningen naar Naturalis in Leiden.

    Volgens Naturalis is al een deel van de insecten aangekomen in Leiden. De dode dieren worden verpakt in 3700 insectenboxen. De gigantische hoeveelheid dode dieren was eigendom van de Wageningen Universiteit.

    Wageningen wilde de collectie liever zelf houden, maar het werd te duur. De beste oplossing is dat de collectie insecten nu naar Naturalis gaat, omdat dit een van de grootste natuurwetenschappelijke centra van de wereld moet gaan worden.
