UK butterflies ‘need good summer’
The Duke of Burgundy butterflies have seen their numbers fall
Butterflies need a warm summer in order to help numbers recover from last year’s washout, say conservationists.
Data from the UK Butterfly Monitoring Scheme showed that eight species were at an all-time low as a result of an unsuccessful summer in 2007.
The main reason behind the decline was an above average rainfall, which meant the insects, such as the common blue, had fewer chances to feed or breed.
Early forecasts suggest this summer could be wetter than average.
