|Abstract||Distribution and ecology of the chironomid Glyptotendipes ospeli in the Netherlands (Diptera: Chironomidae) |
This paper adresses the ecology, biology and distribution of the larvae of the chironomid Glyptotendipes ospeli Contreras-Lichtenberg, 1999. No information is available on the ecology and biology of the adults. Glyptotendipes ospeli was described in 1999 after larvae collected in Amsterdam (the Netherlands) had been reared to adults. There is only one record from outside the Netherlands: a larva collected in Pripyat River (Belarus). In the Netherlands, larvae of this species have so far been recorded on 36 localities. Locally it can be rather common. Most records originate from standing, medium-sized, shallow waters in cities, e.g. ponds in city parks. One quarter of the localities are more or less natural. A large proportion of the larvae was found on hard substrata like wooden sheetings of ponds, submerse natural wood and stones. On several occasions, moss animals (Bryozoa), most likely Plumatella species, were found here. Larvae of G. ospeli were seen in Plumatella colonies. Often there was much leaf litter on the bottom. The water in which the larvae were found is characterized by high conductivity, low levels of dissolved oxygen and a poor transparency. The saprobic valency and weight of the species were estimated at 2.55 and 3 respectively. It is possible that this species previously was overlooked and identified as G. pallens or G. glaucus.
