Invasiviteit Niet invasief
Invasiviteit (toelichting) In the Netherlands the species is mainly found at canals, lakes and stagnant areas of slowly running waters. It is able to survive freezing temperatures and there is no clear association with discharges of heated water as was once believed. Its invasiveness is demonstrated by the rapid expansion through Europe in natural habitats. The species seems to tolerate anaerobic bottoms and prefers waters with submerged wood, twigs, leaves and vegetation.
Type introductie Niet opzettelijk
Jaar van eerste introductie 1986
Jaar van eerste melding 1996
Natuurlijke verspreiding Noord-Amerika
Verspreiding in Nederland
  • Limburg
  • Noord-Holland
  • Utrecht
  • Zuid-Holland
  • Verspreiding in Nederland (toelichting) In the Netherlands at the moment still uncommon, but may be overlooked because of the small size. There are still few reports of populations, a.o.: Honswijk (1986); river Maas near 'stuw van Borgharen' (1996); in Amsterdam canals, i.e. Lijnbaansgracht and Amstel (1997), Merwedekanaal in Utrecht (2004) and at several localities in and around Delft (2005). Thus far the species does not seem to be rapidly expanding its range within the Netherlands.
