Imago Typical Appearance, sorted by earliest date

The table below indicates the appearance times of all of the UK Butterflies, with the exception of rare migrants and extinct species. However, dates may vary depending on locality and seasonal weather, and this table is intended to provide a rough guide only. Each month has four divisions, with each division approximately representing a week. Much of the information contained in these tables has been derived from Emmet (1990), Asher (2001), Riley (2007), Thomas & Lewington (2010), and sightings made by visitors to UK Butterflies.
