The easiest way to find the butterfly is to look for the white eggs on the black twigs of blackthorn in winter; the annual cutting of hedges is considered one of the reasons for butterflies decline. Change of hedgerow management from flailing and annual cutting to more a traditional laying has led to an increase in eggs at six sites, and over three winters, found the brown hairstreak to be stable there. Eggs have increased in three other sites and have returned to two other sites. The change in hedgerow management has increased the amount of suitable, young-growth blackthorn, for egg-laying females. The large blue butterfly has a complex life-cycle with the larva feeding on thyme (

Habitat improvement for the large blue occurred at thirteen locations with contractors and volunteers restoring 8 hectares of limestone grassland, by scrub cutting. The butterfly has since bred on much of this area. To increase the available foodplants, 2,500 plug plants of thyme were grown by
