It was so strong that it could resist evidently the peck of a bird's beak, while it would immediately swing away from one on being touched. I afterwards met with several such cocoons; and once saw a moth coming forth from one. It was of a dull, slatey colour, and belonged to the silkworm family of Bombycidae.
It is also common at Almorah, where the larva feeds almost exclusively upon the 'Kilmorah' bush or Berberis asiatica; while at Mussoorie it will not touch that plant, but feeds exclusively upon the large milky leaves of Falconeria insignis. The worm is, perhaps, more easily reared than any other of the wild bombycidae."
