Typical Flight Times, sorted by earliest date

The table below indicates the typical flight times of all of the UK Butterflies, with the exception of rare migrants and extinct species. However, flight times 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 The Millenium Atlas of Butterflies in Britain and Ireland, The Moths and Butterflies of Great Britain and Ireland Volume 7 (1) Hesperiidae to Nymphalidae (the Butterflies), The Butterflies of Britain and Ireland, British and Irish Butterflies, and sightings made by visitors to UK Butterflies.
