Scalloped Oak

Although there is some variation in the colour and intensity of the wing markings the most familiar form is a yellowish moth with a brown central band and obvious single black spot on the forewing. Other forms are more uniformly orange-brown in colour, deep brown or even blackish. The wings have a lightly scalloped edge.

They overwinter as an egg on the foodplant and the caterpillars can be seen between March and June.
