Come and join us to learn all about the UK's smallest butterfly and how you can help.

The Small Blue is the UK's smallest butterfly and despite the name it is not blue but rather a dark dusky colour with the male having a smattering of silvery blue scales. It is however very small, as little as 16mm, leading to it often being overlooked. Small Blue is found in small patches where the caterpillars sole foodplant Kidney Vetch grows, the colonies are small and often fragmented.

It has undergone a worrying and rapid decline in Scotland over the last twenty years and we are not quite sure why. That’s why this year with the help of Species on the Edge we are relaunching Small Blue Week to raise awareness of the plight of this diminutive and charismatic butterfly.
