After finding an Imperial Moth back in July, I finally have a complete series of photos showing the progression of the offspring from egg to chrysalis. Color variants often appear in this instar.

The caterpillars hatched about 2 weeks later. The above moth laid over 100 eggs over a 2 day period. See Also adult of Western Imperial Moth or Oslar's Eacles ( Eacles oslari ) can be either virtually identical or much darker (see 4 adult images by Bruce Walsh) but is found only in the extreme southwest beyond the range of E. imperialis (see distribution map ) Imperial moths used to be found throughout New England but now, their only New England home is Martha's Vineyard. Imperial Moth Life Cycle.

The scoli of fourth instar larvae continue the progression of shortening in relation to body length and the hairs on the body are much longer. Imperial moth, Eacles imperialis (Drury), third instar larva.
