The eggs have still not hatched. Fortunately, the study site is only seventeen miles from home. It has been twelve days since the eggs were laid, and still no caterpillars. The eggs have darkened in color, however. They are a dark plum now and the clear empty shells certainly stand out amongst them.
Emergence seems close.
The caterpillars have arrived. I missed the emergence but what a great sight to see the youngsters clustered together around the thin branch. They must have hatched a day or two prior to my arrival since they first fed on their birth branch but then moved to a different branch. Their feeding areas can easily be seen because the caterpillars leave silk where they feed and their droppings often adhere to the silk. Oddly enough, they are still at the same height about the ground.
