. They are found throughout Europe, South Asia, Southeast Asia and Sub-Saharan Africa, with less concentrated ranges in the Middle East and Far East.

The range of D. nerii is suspected to have expanded with the cultivation of N. oleander as an ornamental plant into Southeast Asia. However, the species may be more pervasive than suggested by the domestic nature of the larval host plant as D. nerii is likely non-phototaxic or negatively phototaxic, and hence may be under-recorded by light trapping methods

.

In Singapore, the caterpillars of the moth are spotted more often than the adults, which are not attracted to light. Hence it may be easier to observe the immature larvae that have more limited mobility and do not actively avoid lit areas. Map 2 below shows recorded locations for the larvae of D. nerii. These locations are, from east to west, East Coast Terrace, Terang Bulan Ave, Yishun Ave 11, Mt Imbiah, Ngee Ann Polytechnic, and College Ave West.

Diagnosis:

Although adults are generally used as standard type references, it is important when identifying this species, to be familiar with each stage of the lifecycle. The descriptions taken from Pittaway (1997-2013) are as follows:

Imago (final moult): Adults generally reach a wingspan of about 10 cm. At rest, the head tends to be tucked in 
and wings are held dorso-ventrally horizontal, angled towards the posterior, but not folded over the abdomen. The adults have wings with entire edges and a pointed apex on the forewing. The wings and body are usually green, pink, white and grey on the dorsal side with a smooth, banded pattern of curved lines.
