The mottled golden wings of the chequered skipper butterflies were once a common sight along the edge of forest tracks in Britain until they nearly disappeared in 1976 after decades of habitat loss.
Lepidopterists trapped swarms of adult butterflies in Belgium this week and transported them to the UK ahead of their release in the Rockingham Forest, Northamptonshire.
Butterfly Conservation, which runs the project, said it was an "important milestone for conservation" and is a "first in a series of planned releases".
