Silver-spotted skipper  (Hesperia comma)

Agri-environment schemes: These schemes allow the government to compensate farmers for using methods that benefit the environment. The two main initiatives in the UK are the Countryside Stewardship Scheme and Environmentally Sensitive Areas. Since October 2000 these have formed part of the England Rural Development Programme (EDRP), administered by DEFRA, the Department of Environment Food and Rural Affairs.
Larvae: Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.
Metapopulations: A set of local populations within some larger area, where typically migration from one local population to at least some other patches is possible.
Myxomatosis: A contagious viral disease in rabbits.
Pupation: The process of becoming a pupa, the stage of an insect's development, when huge changes occur that reorganise the larval form into the adult form. In butterflies the pupa is also called a chrysalis.
Single-brooded: Also known as ‘univoltine'. Referring to an organism which has just one brood each year.
