Natural pastures, which are not fertilized or used for cultivation, have been used for grazing for a very long time.

These have long been the ideal place for pollinating insects because there are both food and habitat.

- In connection with the agricultural landscape has intensified, the amount of flowering plants has decreased, says Julia Weber.

SVT meets researchers Julia Weber and Romain Carrié from Lund University on site at Öja in Klippan municipality - both with the nets in full swing.

Today they will collect insects to see where they thrive and how many there are.

The project investigates whether so-called grass cultivation with, for example, clover can function as a substitute for the meadow flowers.

- I am investigating whether what is grown in the surrounding agricultural landscape can function as a complementary food source for the pollinating insects in natural pastures, says Julia Weber.

- The good thing about clover is that it blooms several times per season so there is continuous food for the insects, she says.

It turned out to be a Lemon Butterfly (Gonepteryx rhamni).
