Green Hairstreak

Callophrys rubi
28 May 1977 27 May 1978


In our area, Green Hairstreaks are found mainly on the unimproved limestone grasslands of the Cotswolds. Scrubby areas in grassland or woodland, and old quarries and railway lines also provide suitable habitat. The species can use a wide range of larval foodplants, both wild flowers and shrubs.

It is unusual to see more than a few of the butterflies, although this sometimes happens. Early one evening a quantity were observed on a Crab Apple tree on a grassland site, and on another site flowers of Columbine (Aquilegia vulgaris) attracted a number of the butterflies, making them much easier to find than usual.

Conservation Issues

Loss of unimproved grassland habitat and succession of scrub to woodland are probably the main threats to the species.

Flight Period

Mostly late April to mid June.


Throughout the Cotswolds, and in parts of the Forest of Dean. The species is very easily overlooked, and it seems likely that it also occurs in some of the less well-recorded parts of the area.
