About Cyclophora punctaria (Linnaeus, 1758)
Cyclophora punctaria (Linnaeus, 1758) has a wingspan of 13–25 mm for its first generation. The second generation is typically much smaller, reaching only about 22 mm. Its forewings have a sand-colored base, and may also have reddish or yellowish tints. The wing pattern is variable. A medium-sized, slightly curved, brown cross line is always clearly marked on the wings. Basal to this cross line is a strongly curved row of dots; distally to the cross line is a slightly curved row of dots. An additional row of dots runs along the wing margin. The wing fringes match the base color of the wings. All these pattern elements continue onto the hindwings. The discal marks match the base color of the wings, so they are hardly visible. The larva is smooth and slim, and is very variable in color, appearing green, brown, or grey. On the sides of the larva there are red and yellowish-white spots framed by yellow oblique lines. On the dorsum, the larva has a variety of U-shaped black spots. The pupa is yellowish-brown to greenish, with four rows of large, dark back spots. Six strong bristles sit on the cremaster of the pupa.
