Box turtles probably benefit man by destroying large numbers of crop-damaging insects (locustids and noctuid caterpillars).
Genitalia of a male noctuid from below : the parts separated out.
Mller mentions a most extraordinary fact of one of the noctuid, which when disclosed from the pupa retained the head of the larva.
On the whole, members of this family are more available to the day collector than are those of the noctuid.
For example, the caterpillars of some species of Xanthia and other noctuid moths feed at first upon willow-catkins.
For instance Plotheia frontalis, a noctuid which often abounds in Ceylon, shows an equally bewildering wealth of forms.
