Late July
- The moths, the adult form of the species, usually emerge from pupation, mate and lay their eggs between late July and sometimes as late as the end of September. The eggs are laid in masses, or plaques, about 2-3 cm long on high branches and twigs. The egg plaques remain on the trees during the following autumn and winter.
