Small Blue (Cupido minimus)
The smallest of the UK’s resident butterflies, it can be seen feeding on Horseshoe Vetch and Bird’s Foot Trefoil but only where Kidney Vetch also grows - the sole food for its caterpillars. We are growing all these plants on our bank and are overjoyed to find that we have eggs on our Kidney Vetch. As the Small Blue is a priority species in the UK Biodiversity Action Plan we are very proud of this success.
