Just because it is so beautiful. Megachile laechella. Rare in the Netherlands, but locally abundant in the dunes of Terschelling. The Dutch name 'zilveren fluitje' means silver whistle, after the high tone it makes while flying and the colour of.., well just look at it.

They seem to be a lot less shy on Terschelling (NL). Took this one yesterday with my phone.

Bees and beers. The typical use of fridges by pollinator ecologists during field season.

In another project restpoll.bsky.social we investigate whether flower plantings can improve pollen dispersal between subpopulations. Scientists in action.

What are the consequences of pollinator decline for wild plants? Here we try to find out in @valor-project.eu. Interesting observations. I never see Centaurea jacea flowers with pollen. But keep the pollinators away and the flowers are dusted white. Very popular species.

Our farm trials across England have shown cover crops can increase earthworms by 65% in the following cash crops! AND agroforestry promotes worms too, especially in drought years π
Hope to see you there!πΎ

The geveltuin (βfacade gardenβ) policy is found in most Dutch municipalities, as here in Delft. Provided they meet a set of requirements, including preserving footpath width, residents are encouraged to remove paving stones in front of their property and replace them with greenery. No permit needed.

A young planted hedgerow with installed next boxes on wooden poles, and in the background a long pole with a kestrel next box installed. The nest box has two common kestrels sitting in it.
Doing science biodiversity is great, but the impact is usually not very tangible. Together with citizen cooperative Land van Ons (@landvanons.bsky.social) we planted 300 meter of native hedgerow last December, and installed nest boxes. Today, I jumped of joy because the kestrel box is occupied!

LOL. Protect the insects with Unilux screendoors. Almost sorry I don't need them
