Did you know?
The Comma gets its name from the small white comma-shaped mark on its closed underside — when resting with wings closed it looks exactly like a dead, ragged leaf

The Comma has expanded its UK range northward by over 150 km since the 1970s — one of the clearest documented examples of a species tracking climate warming
