Ovum. Large, with two brown stripe round the
perimeter.
Foodplants. This species is polyphagous. Larva
feed on more than 50 species of trees (Ferguson
1972) including oak, maples, plum, apple. For a complete list look
at Bill Oelkhe page.
Personally I use Fagus sylvatica in summer and Quercus ilex
in winter.
Larva. The fifth instar larva average 8 cm.
They are easy to rear and grow very fast, expecially in summer.
Cocoon. Small and very hard in touch. Covered
with a white powder.
