Bees spin over the hot sand on a Texas ranch.
All except one are males, intent on mating with the single female at the centre.
The buzzing ball of cactus bees competing for a single female has earned its photographer the coveted title of Wildlife Photographer of the Year.
The picture, captured by American photographer Karine Aigner, is the grand title winner in this year's Wildlife Photographer of the Year competition — an annual award given out by the Natural History Museum in London.
She is the fifth woman in the competition's 58-year history to be awarded the Grand Title award.
Wildlife Photographer of the Year is one of the most prestigious competitions of its type in world photography.
Sixteen-year-old Katanyou Wuttichaitanakorn from Thailand was awarded the Young Wildlife Photographer of the Year for his image of a baleen whale.
When a Bryde's whale surfaced close to the boat, the young photographer was intrigued by the contrasting colours and textures of its dark skin, pink gum and the brushlike mass of baleen hanging from its upper jaw.
The two Grand Title winners were selected from 19 category winners.
The competition attracted 38,575 entries from 93 countries and were judged anonymously by an international panel of experts on their originality, narrative, technical excellence, and ethical practice.
The images awarded showcase the natural world in all its diverse glory.
