Phasmid Eggs

The question "the chicken or the egg?" or as I like to say....."the Phasmid or the egg?".

Which came first?


I know that when the first adults died I had left was 21 eggs. If I didn't have those 21 eggs I am not sure if either of the two breeding groups would have survived.

The diagram and photographs below (figures 1 to 3) show the morphological detail of phasmid eggs.

Note eggs in figure 2 & 3 are from Dryococelus australis.
