Armyworms, Borers and related species
What are they?
Armyworms are named after their larvae which have become notorious for occuring in great numbers periodically and moving en masse after depleting their food supply - which may often be crop plants. Borers are also named after their larvae which tend to feed by tunneling inside the stems of their foodplants. This section pulls together a fairly large cluster of species in the Noctuidae, contained in six tribes in the subfamily Noctuinae: Prodeniini, Caradrinini, Dypterygiini, Actinotiini, Phlogophorini and Apameini.
Identification
A large group and consequently rather diverse. Many are distinctively and boldly patterned and thus easily identifiable. Many are very common (especially the armyworms) and come readily to light.
