continuously in captivity, however moths emerge very irregularly. Synchronizing broods is a nightmare.
Betulaceae (Betula, Corylus, Carpinus, ...), also Salix
Not for newcomers. Keep at room temperature or warmer, in closed plastic containers when young. Older caterpillars can continue in large, plastic containers however more air movement is needed (replace the closed lid by a mesh cover or another breathable fabric) or move to a netted cage. Replace the food often, this species respond very badly to poor quality of food. Do not spray, do not give wet leaves, watch out for condensation. Keep very clean. Do not overcrowd. Relatively fast growing. It can take in between 6 and 7 weeks before they start to pupate (depending very much on the rearing conditions, the warmer the faster). The pupal stage can be very long (more then a year).
