Grape hawk #6 reared

25 June 2017:

I am trying to learn how to tell the small annual invasion of similar but (I suspect) different hawk moth caterpillars on my grapevine apart. Today I collected #6 of my experiment.

22 July 2017:

The caterpillar spun a loose cocoon among bits of frass and food plant at the bottom of its tub.

5 September 2017:

Adult moth emerged.
