A species of woodland, parkland, gardens.

Note Cannot use flight time to separate from September Thorn as both can occur in July! The outer cross-line is usually kinked where it meets the leading edge of the wing - not so in September Thorn. Inner cross-line of August has a longer, and more pronounced angle where it meets the wing edge. Also August holds its wings at a lower angle
