Orange Tip butterfly on a Bluebell, Thunderbridge, West Yorkshire
Today's warm weather brought on the first appearance of Orange Tips this year. There weren't many potential nectar sources around so they repeatedly landed on the Bluebells.
They only have a single emergence, usually during April and May. This is a male with orange tips to the forewings. Females are similar, but lack the orange, making them hard to distinguish from the other small white butterflies on the wing.
The scientific name is Anthocharis cardamines; Anthocharis means grace of flowers. Cardamines is the name of Cuckoo-flower, which is one of their main larval foodplants.
