Female rosy maple moths lay their eggs one day after fertilization. During those 24 hours, the eggs are protected inside the body of the female. Besides this, rosy maple moths exhibit little parental care, as the female leaves after depositing her eggs. Females typically lay around 150 to 200 eggs in groups of 10 to 40 on the underside of ...
Viburnum opulus is a deciduous shrub growing to 4–5 m (13–16 ft) tall. The leaves are opposite, three-lobed, 5–10 cm (2–4 in) long and broad, with a rounded base and coarsely serrated margins; they are superficially similar to the leaves of some maples, most easily distinguished by their somewhat wrinkled surface with impressed leaf venation.
The larvae start to eat the inside of the leaves in August, and damage develops from the late summer to the early spring, with heavy attacks leaving the foliage disfigured by spring. [ 26 ] To control heavy infestations, the leaves can be removed and destroyed during the winter months before the adult flies emerge.
The rosy maple moth (Dryocampa rubicunda) also lays its eggs on the leaves of maple trees, including Acer negundo. The larvae feed on the leaves, and in very dense populations can cause defoliation. [25] Small galls are formed on the leaves by a bladder mite, Aceria negundi.

The leaves are broad and soft, 8–15 cm (3–6 in) long and 6–12 cm (2.5–4.5 in) broad, with three shallow forward-pointing lobes. [ 3 ] The fruit is a samara ; the seeds are about 27 mm (1.1 in) long and 11 mm (0.43 in) broad, with a wing angle of 145° and a conspicuously veined pedicel.
