      Life history

      The imago flies from April to October in two or three generations dependant on locality and altitude. The larva feeds on grasses in the genera Festuca, Bromus, Deschampsia, Poa, Dactylis and Brachypodium.

      "The egg is pale green when first laid, and in shape it is almost spherical, but rather higher than broad ; it is finely ribbed and reticulated, but unless examined through a lens it appears to be quite smooth. The caterpillar when full grown is whitish-green, dotted with white. From the larger of these dots on the back arise greyish bristles ; the three lines on the back (dorsal and sub-dorsal) are whitish, edged with dark green ; the line on the sides (spiracular) is white, fringed with greyish hairs ; anal points green, hairy, extreme tips white. Head larger than the first ring (first thoracic segment), green dotted with white and hairy,jaws marked with brownish.The chrysalis is green, with yellow-tinted white markings on the edge of the wing covers and ridges ; the spots on the body are yellowish, or sometimes white. Occasionally the chrysalids are blackish, with white or yellow points on the body. (South 1906)
