The Butterfly World Project is located near St Albans, in the county of Hertfordshire in the UK.
The center collects and breeds butterflies from the tropics and from the UK. The aim, especially with the UK species, is conservation. Of the 54 resident butterfly species in the UK, (there are four regular migrant species also), seven out of ten are in decline.
The key attraction is the tropical center, which has between 500-800 butterflies, from 15-20 species.
Here are a selection of the images I took:
Butterfly World also contains a number of other insects. These are not as pretty as the butterflies but no less interesting.
The attraction also has many interesting themed gardens.
