Dropworm \Drop"worm`\ (dr[o^]p"w[^u]rm`), n. (Zool.)

Note: The autumnal species ({Anisopteryx pometaria}) becomes
adult late in autumn (after frosts) and in winter. The
spring species ({Anisopteryx vernata}) remains in the
ground through the winter, and matures in early spring.
Both have winged males and wingless females. The
larv[ae] are similar in appearance and habits, and
belong to the family of measuring worms or spanworms.
These larv[ae] hatch from the eggs when the leaves
begin to expand in spring.

three pairs of true legs, and several pairs of abdominal
fleshy legs (prolegs) armed with hooks. Some are hairy,
others naked. They usually feed on leaves, fruit, and
succulent vegetables, being often very destructive, Many
of them are popularly called worms, as the {cutworm},
{cankerworm}, {army worm}, {cotton worm}, {silkworm}.
[1913 Webster]

2. (Bot.) A plant of the genus {Scorpiurus}, with pods
resembling caterpillars.
[1913 Webster]

caterpillars. The name is also given to several other
birds.
