Eupanacra elegantulus
Eupanacra elegantulus is a moth of the  family Sphingidae. It is known from south-east Asia, including Singapore, Thailand, Malaysia, Indonesia the Philippines.

It is similar to Eupanacra mydon, except for the pattern elements found on the upperside of the forewing which are much clearer. Furthermore, the discal spot is larger in males and more prominent in females since these have a paler ground colour. There are two rows of black dots and a large black spot on the underside of the abdomen.

The larvae have been recorded feeding on Aglaonema, Alocasia, Dieffenbachia, Syngonium and Monstera deliciosa. Young larvae are slender, pale green and have a straight pale pink spine at the end of their bodies. Feeding takes place at the underside of the leaves of their host. They rest near the base of the stems. There are green and brown forms of the last instar larvae. Pupation takes place in a loose silken cocoon, which includes some debris.
