SPECIES OF THE MONTH
Red admiral
Each month we choose a particular species, highlighting its unique characteristics and habitat, and ask our members and supporters to report any sightings in their garden or local green space using the interactive map on our website. We send all the sightings to the Dorset Environmental Records Centre (DERC), who collate the information to build a better picture of the state of Dorset’s wildlife.
In March, our species of the month is one of our most familiar butterflies, the red admiral. This distinctive beauty is an unmistakable garden visitor and may be seen feeding on flowers on warm days.
Starting each spring and continuing through the summer, red admirals migrate northwards from North Africa and continental Europe. The migrant females lay eggs and consequently there is an emergence of young butterflies from July onwards. They continue flying into October or November and are typically seen feeding on nectar-rich buddleias, flowering ivy, and rotting fruit. The most important and widely available larval foodplant is the common nettle.

Did you know?
Red admirals seen in autumn usually migrate south back to the continent. Due to the warmer winters, however, red admirals are overwintering in the UK, especially in southern counties like Dorset.
