This photo of the Great Yellow bumblebee is one of the twelve selected for the 2027 calendar of the @bumblebeetrust.bsky.social Long time ago Dave Goulson said that people had to be able to see how magnifiscent those creatures are and he was right. This is my contribution.

Bombus Consobrinus (Lushatthumla) is the bumblebee with the longuest tongue of Scandinavia. She is dependend on Monkshood (Tyrihjelmen). On the first shot she cleans her tongue. Funasdalen, Sweden, July 2026. Enjoy!

Different bumblebee species like to nest in different places, including long, tangled grass, bird boxes, and underground in abandoned rodent holes. They can even nest in more creative places, like under the edge of a pond. What is the most interesting place you have found a bumblebee nest?

The lovely Bombus mastrucatus (formerly named Wurflenii) shot in Sweden last july. Look at the strong jaws of this bee. It often opens the flowers at the top of the corolla stealing nectar without pollination. Beacause of this the scandinavian name is Tyvhumle wich means "stealing bumblebee".

Save money & reduce waste! Use toilet roll tubes as biodegradable seed starters for your veggies. They hold moisture well, promote root growth, & can be planted straight into the soil! Just stand them in a tray, fill with seed mix, & sow. Perfect for peas, beans, & root crops. #SustainableGrowing
