Conservation of the purple hairstreak butterfly in UK oak woodland canopy habitats.
Key Facts
Purple hairstreaks live predominantly in the oak canopy and are often overlooked
Adults feed on honeydew and are rarely seen at ground level
Larvae feed exclusively on oak leaves and require mature oak woodland
Populations are relatively stable compared to many other UK butterflies
Evening observation at oak canopy level reveals their true abundance at suitable sites
Welfare Considerations
Individual purple hairstreak larvae depend on mature oak canopy habitat, with ancient woodland conservation directly supporting population welfare and viability.
