    The eggs are white flattened spheres, covered with a minute raised lattice of about 200 polygons, each with raised edges and small spikes at the corners. The eggs are laid singly on the undersides of foodplant leaves, and have a diameter of about 0.8 cms.

    The species is found in:

  • Queensland.

    Philiris diana has two subspecies, both occurring in Queensland:

  • diana, and
  • fortuna Hacobian et al, 2023.

    Philiris papuana was at one time thought to be a subspecies of Philiris diana until it was proved to be a separate species.
