2026/10/05

Slovenia — a country the size of New Jersey — is home to 575 bee species, more than a quarter of all species known in Europe. It's the birthplace of the Carniolan honeybee, but it's also a hotspot for wild and solitary bees. This week, we sit down with Dr. Danilo Bevk, a researcher at the National Institute of Biology in Ljubljana and founder of the SloBees Society (Čmrljica), to talk about Slovenia's remarkable pollinator diversity, a citizen science project tracking bumblebee queens across the
