Field trip
10.00 Bus leaving in front of the museum

The excursion will first go to `Meijendel'. This is a dune area near the coast, with sand dunes and small pieces of forest. Here we will have about 2 hours to walk around and collect hoverflies. After that we will have lunch.

After the lunch we will again go by bus to `Kortenhoef, which is an area of fenland, typical for the Netherlands. Here we have about 2 hours to walk around and collect flies. After that we will go by bus to the museum again, arriving around 18.00 hours.
