Crompus opacus

Crompus opacus is recognizable by the white veins in the transparent surface of the forewing, and by the elongated head.[1] While the first description of the species by Geoffery Scudder indicated that the first antenna segment is always black, the color can be black, light yellow-brown, and sometimes pale white like the second segment of the antenna.[1] The pronotum occasionally has dark markings, including often a dark stripe down the center and a dark band at the base of the wings.[1]

This species breeds on various species of myrtles (Myrtaceae), including Taxandria linearifolia, Kunzea recurva, and species of Leptospermum.[1] Crompus opacus is particularly common on the flowers of bush species between 2.5 and 3.5 meters tall growing in damp or moist areas along roads.[1]
