species: insocia Walker (N.E. Himalaya).
Seudyra Stretch (type species transiens Walker).
is a relatively homogeneous, primarily Oriental genus of species with dark grey
forewings patterned with white, brown, and violet in a reticulate manner, and
showing characteristic noctuid features such as reniform and orbicular stigmata;
these stigmata are usually large, and there is often a diffuse white bar distal
to the reniform.
the male genitalia the uncus is not elongated, and the scaphium is not heavily
sclerotised. The valve is straplike with a corona and a relatively slender harpe
that varies in position from relatively basal to being in the distal half of the
female genitalia are typical of the subfamily.
(MS) reared S. albifascia Walker and S. venosa Moore in India and
Sugi (1987) illustrated the larva of S. subflava Moore and S. venusta
Leech. The larvae are mainly black with white, pale grey and orange irregular
reticulations or broken lines, with long primary setae, often white, arising
from tubercles or chalazae.
larvae tend to live on the underside of the young leaves on which they feed.
Pupation is in rotten wood or soil in a silken cocoon.
