The caterpillars are greenish or light brown and show dark brown dorsal and lateral lines as well as loose short hair. The dorsal line is sometimes extended onto the segments. The pupa is brownish, the wing sheaths often shimmer slightly greenish. The cremaster is equipped with a total of eight hook bristles, the middle pair of which is more powerfully formed.
