When @omearabrian.bsky.social saw the manuscript, he described it as: ‘What if this figure could be an entire paper?’
I choose to interpret that as high praise.

Bombus Consobrinus, Norway 2022.
This bee has the longest tongue of all scandinavian bees.
It is specialised on Monkshood flowers with deep corolla's.
Lovely, very fast, quite large bees 😘

One of my favourites, it took two vacations in the French alps to find these beauties. Bombus Brodmannicus, a specialized bumblebee dependend on Cerinthe. This was 2023 July.
Mind: running on a slope diving low to shoot the bees hanging under low flowers being very shy 😍 Very Mindful activity.
