Shell lerp psyllid

Shell lerp psyllid
Spondyliaspis cf. plicatuloides
Sap sucking

Purpling of the leaf, on the opposite side of the lerp.

Clusters of dark brown shell-like structures (lerps) that are scalloped.

Not much is known about the genus Spondyliaspis as it has been little studied in its native range and South Africa is the first country where it has been reported outside its native range.

As with many of the Australian psyllids, the nymphs of S. cf. plicatuloides create a lerp or shell-like structure that they feed and develop under (Hollis 2004). At the end of their development, nymphs leave the protection of the lerp and become adults. Adults lay eggs in clusters on the leaf surface.
