The eggs of D. atronivea are laid from the end of October.
They are oval in shape, slightly roughened on their surface and start out green in colour, turning a light blue shade covered with purple spots after approximately a week and then to a light purple colour just prior to hatching.
The eggs are laid singularly and hatch after 11 days.
Although the larvae are generally brownish or blackish green in colour they can vary in shade significantly.
The pupae inhabit a light coloured cocoon which they form amongst leaves on the surface of the ground.
The adults emerge in February and March.
Some overwinter as pupae while others transform into adult moths.
