At first glance, the potter wasp appears to be riding a broomstick.

But this industrious insect isn't flying back to stir its witch's cauldron, or playing Quidditch. It's carrying a caterpillar – prey to feed its young.

It was captured by macro wildlife photographer Bidyut Kalita and was among the runner-up or 'highly commended' entries in this year's Wildlife Photographer of the Year competition.

The winning images will be announced on 14 October, followed by an exhibition at the Natural History Museum, showcasing 100 standout photographs from around the world.

Title: No Place Like Home

Photographer: Emmanuel Tardy (France)

Location: El Tanque, San Carlos, Alajuela, Costa Rica

Photographer: Bertie Gregory (UK)

Location: Ekström Ice Shelf, Atka Bay, Antarctica

Mr Gregory captured a group of fledgling emperor penguin chicks teetering on the edge of an ice shelf.

After spending two months observing the colony, he saw most chicks using natural ice ramps to descend safely to the sea – but this group had missed the easier route down.

Left to fend for themselves, emperor penguin chicks must eventually take a leap into the icy ocean for their first attempt at feeding.

Scientists believe that the decline in sea ice may force penguins to breed on ice shelves, making leaps like this a more common thing.

Title: Slime Family Portrait

Photographer: Kutub Uddin (Bangladesh/UK)

Location: Slindon Wood, West Sussex, England, UK

Mr Uddin discovered a grouping of slime moulds arranged on a fallen log in a forest. He described the scene as a "bizarre family portrait," complete with a tiny yellow insect........
