These caterpillars are green with black spots. They feed on various species in ASTERACEAE, including :

  • Capeweed ( Arctotheca calendula ),
  • Spear Thistle ( Cirsium vulgare ),
  • Fleabane ( Erigeron canadensis ),
  • Scotch Thistle ( Onopordum acanthium ) and
  • Everlasting Daisy ( Xerochrysum bracteatum )..

    The caterpillars eat the flesh of the leaves leaving the skin intact, which is transparent and looks like small windows in the leaves.
