Copernicus now has honeybees at the Hortus and it was time for their first inspection. They do well in the Hortus with this weather. Linden (Tilia) is blooming in the Uithof and giving a lot of nectar after the rain. The bees turn it quickly into new wax combs and honey stores.
Having institute bees gives interesting research possibilities, from developping and testing measuring systems to using the bees themselves as environmental monitors.
Note for the beekeepers in the public: you see foundationless frames, bees are on their own comb. And the bees have a high percentage of native black bee in them.
