Keepers at ZSL Whipsnade Zoo are currently celebrating particularly high numbers of butterflies this autumn in the Zoo’s tropical Butterfly House.
The chrysalis-shaped Butterfly House, which is one of the largest butterfly biomes in the UK and features colourful butterflies from around the world, is currently alive with hundreds of the delicate, fluttering creatures, thanks in part to temperate weather conditions.

Team leader Alex Cliffe said: "All our species, from the shimmering blue morpho butterfly to the Atlas moth, which is one of the largest in the world, seem to be thriving."
Team leader Alex Cliffe said: Although we keep conditions within the Butterfly House warm and humid all year round, the butterflies love this time of year when the outside temperature isnt too hot or too cold."
