157508 Wall Brown - Lasiommata megera - eggs. Wingspan 45mm. A well-marked, sun-loving butterfly. Adult has orange-brown upperwings; patterns and colour recall a fritillary butterfly but note the small eyespots on the wings. Double-brooded: flies April–May and July–September. Larva feeds on grasses and is strictly nocturnal. Widespread in England and Wales but declining and now rather scarce; easiest to see on grassy heaths and on coasts.
