Foeperpot, aculeatenrijkdom op een snipper van twee hectare

We collected quite a surprising amount of aculeates in a two-hectare, isolated, marshy meadow reserve in Groesbeek: 33 species of bees and 19 other species of aculeates. These were found during two visits in 2009 and six visits in 2010. A new species for the Netherlands was discovered during the visit in 2009, and this was the reason for the series of visits in 2010. One could possibly explain the diversity by showing a positive feedback between nature reserve and nearby development. The nature reserve provides flowers; the shrubs, gardens and paths provide nesting. And that could be scarce in that wet area.
