The Pamphlet Collection of Sir Robert Stout: Volume 14

Life History

The perfect insect appears about the middle of June. The female soon begins to lay eggs. Though these are very plentiful they are only deposited singly. After fourteen days the larva or caterpillar comes forth and crawls to the root of the hop plant, or other plants, as the dock, and burdock, where it remains feeding with great appetite until April. At this time it assumes the pupa stage and emerges from the ground as the perfected imago.
