it shares the diagnostic facies features, such as the variable reniform, and has
the larval characters that Thyas shares with Artena.

preference. Records are infrequent, and the species may not come readily to
light, but they are from forests, disturbed habitats and offshore islands (Karaman
Is.) in the lowlands up to 2600m, where eight specimens came to light, possibly
hill-topping, as the species is a known migrant.
The larva was described by Bell (MS), Gardner (1941, 1947) and Sevastopulo
(1939a), and described and illustrated by Bigger (1988). The young larvae are
green with black spots, slender. The mature larva is also of typical slender
ophiusine shape with the head prognathous. Head and body are striped
longitudinally. The stripes are alternate pale fawn and darker purplish fawn,
(these are relatively broader on the head), separated by fine darker brown
lines. There is a sequence of three of the darker stripes on each side, and a
thinner dorsal one that is expanded into ellipses on A5 and A6. The dorsolateral
stripes contain a pair of small, pale yellow tubercles on A8. The prolegs of A3
and, to a lesser extent, A4 are reduced. These features are identical to those
of the larva of T.

of the life stages, the whole cycle lasting 51-57 days.
