The winners of this year's Natural History Museum Wildlife Photographer of the Year competition have been making a buzz with some stunning shots of nature at its finest.
First spot in the 'Behaviour, invertebrates' category went to Karine Aigner from the US, who captured a ball of huddled cactus bees spinning over hot sand at her southern Texas ranch.
All except one of the bees in the pic aboce are males, who are fighting with intent on mating with the single female at the centre.
