Blenheim Palace's butterfly house has undergone a significant transformation since the start of the year to improve accessibility and visitor experience.

Head gardener Andy Mills and senior gardener Chris Horne, who has cared for the butterfly house for more than a decade, have introduced a range of new spring flowers like amaryllis and fritillaries.

These flowers now sit alongside exotic plants from destinations including Africa, Madeira, and South America.

The aim was also to make the building an "even better environment" for butterflies.

Substantial modifications have been made, such as the roofing of the middle pond to ease visitor access to the house's centre.

To promote diets that mirror those of their natural habitat, the butterfly diet now includes a higher proportion of tropical fruits such as pineapple, mango, and papaya.

The butterfly house took a tech-driven approach last year by adopting new technologies that monitor temperature, humidity, and butterfly hatch rates.

The house welcomed 38 new species of tropical butterflies in 2023.

The butterfly house now hosts vibrant residents as the Red Lacewing, the Emerald Peacock, and the Blue Wave.
