Sympistis lapponica
Sympistis lapponica is a small noctuid moth first described by Thunberg in 1791. It occurs across boreal and arctic regions of the Northern Hemisphere, including Fennoscandia, northern Russia, Asia, and northern North America. The species is notable for its two-year life cycle, overwintering first as an egg and again as a pupa.
