The National Biodiversity Data Centre have developed an online eCourse in butterfly identification. This course is suitable for those who are completely new to butterfly identification and those who want to brush up on their skills as another season of recording starts.
This is a detailed eCourse for butterfly identification, showing features of upper and lower wing and any physical differences between males and females. This resource can be used to complement our ‘swatches’ which are small handheld identification guides that can be used while you are out in the field. Swatches can be purchased through our online shop
