Descriptions of Larvae of Forest Insects: Syngrapha, Autographa (Lepidoptera: Phalaenidae)1

Published online by Cambridge University Press:  31 May 2012

Extract

The larvae of the plusiine genera Syngrapha and Autographa have but two pairs of ventral ahdominal legs; typical phalaenid larvae have four pairs of these legs. The setal arrangement seems to be fairly constant. Intraspecific variation in setal positions seems to be as great as interspecific. The patterns on the head (Figs. 2 and 3), thorax (Figs. 1, 6) and abdominal segments two and six (Fig. 5) are illustrated. The setal classification nf Hinton (3) has been used here.
