Lycaena Phlaeas
This butterfly favours open land where nectar sources and food plant are found. Such habitats include grassland, wasteland, heathland, old quarries, embankments, road verges and woodland rides.
There are typically 2 or 3 generations each year, depending on the weather, with 4 generations in extremely good years. The first adults emerge in May, occasionally at the end of April, with the last adults being seen around the middle of October, depending on location. The main larval foodplants are Common Sorrel (Rumex acetosa) and Sheep's Sorrel (Rumex acetosella) though Broad-leaved Dock (Rumex obtusifolius) is also used. It overwinters in the larval stage and pupates in April.
