The large copper (Lycaena dispar) is a butterfly of the family Lycaenidae. L. dispar has been commonly arranged into three subspecies: L. dispar dispar, (single-brooded) which was commonly found in England, but is now extinct, L. d. batavus, (single-brooded) can be found in the Netherlands and has been reintroduced into the United Kingdom, and lastly, L. d. rutilus, (double-brooded) which is widespread across central and southern Europe. The latter has been declining in many European countries, due to habitat loss. Currently L. dispar is in severe decline in northwest Europe, but expanding in central and northern Europe.
