Delphacidae (Planthoppers)

Delphacids are recognised by the presence of a large movable spur at the apex of their hind tibiae. The brown planthopper (Nilaparvata lugens) is a pest of rice in tropical regions including Queensland. However the majority of delphacids are not considered of economic importance and are generally found on grasses, sedges and rushes.

Nilaparvata myersi, originally described from a New Zealand specimen, is the only recognised species for Tasmania. Nilaparvata is a genus notable for the presence of one or more slender spines on the hind basitarsi, however in N. myersi these can often be missing. Like many delphacids, the adults have short-winged forms (brachyptery) and full-winged forms (macroptery).

We are uncertain of the specific identity of the delphacids photographed below.
