Purple Hairstreak (Neozephyrus quercus)
Cheshire local information
When to see: July-August
Where to see: Anywhere with the presence of Oak trees
Caterpillar food plant: Pedunculate Oak (Quercus robur) and Sessile Oak (Quercus petraea)
Cheshire status: Formerly considered scarce, but with recent survey work revealing many new breeding sites, especially on the Wirral and in the south-west of the county. This is an inconspicuous treetop butterfly that has probably been overlooked in the past, although there is evidence to suggest some range extension in recent years. Single-brooded flying from late June to mid-August.
