Habits as in the preceding species, but this is less common. Family : Noctuidse {Owlet Moths). Night-flying moths, of medium size and dull colour, with smooth-haired bodies. Antennee long and thin, thread like,—comb-shaped only in the males of a few species; wings powerful, lie in a roof-like way when at rest; almost always a wing-hooklet. Caterpillars usually hairless ; mostly with five pairs of pro-legs, a few with four or three pairs. The owlets pair at night; they also fly about during the day, even in bright sunshine. Flight strong and rapid, but always in fits and starts. Almost all species lay their eggs.
