Species Profile
Mythimna turca, the double line, is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in 1761. It is found in Europe. The eastern expansion extends through northern Asia and central Asia to northern China, Korea and Japan. It rises to a height of about 700 metres in the Alps.
The Double Line (Mythimna turca) faces significant pressure from habitat loss due to agricultural intensification and urbanization across its range. Climate change is altering precipitation patterns and temperature regimes, affecting the availability of host plants and disrupting breeding cycles. Pesticide use in agricultural areas poses additional risks to both adult moths and larvae.
Key Facts
