Small Tortoiseshell

How to identify: the Small Tortoiseshell


Scientific name: Aglais urticae

Why are we looking for it?

This beautiful butterfly used to be found in large numbers throughout the UK, but it has suffered a rapid decline in recent years, especially in southern England. Research into the cause of this decline is ongoing, but a recently introduced parasitic fly called Sturmia bella is likely to be one factor.

Help us find out more about this once common garden species – where is it now and is it doing better in urban or rural areas?
