Dr Simon Spencer was trained as an entomologist and has worked on the conservation of butterflies in Wales and Shropshire for 25 years having been interested in butterflies all his life. He has led many informal trips to Europe to see butterflies and was the chairman of Butterfly Conservation’s European Butterflies Group (EBG) for many years.  He is a part time farmer and is particularly interested in the effect of changes in grazing on butterflies.

He and his wife have travelled extensively in Europe in a camper van looking for butterflies and occasionally filming them.  He has been part of several collaborative projects in Europe where UK butterfly people work with local butterfly enthusiasts to survey and monitor butterflies.
