Two-lined Gum Leafhopper - Eurymeloides bicincta

Family Cicadellidae, Eurymelinae, Eurymelini    

This page contains pictures and information about Two-lined Gum-leafhoppers that we found in the Brisbane area, Queensland, Australia.
 
Adult body length 8mm
 
This Gum-leafhopper is usually found during early summer in Eucalypt forest. Many of them are found on young gumtrees.

Adults were black in colour with two narrow white lines on wings. Head is largely brown or black. The eyes are orange in colour. Pronotum is black, dark brown or orange-brown in colours usually with the white hind margin. Scutellum is either black or orange-brown. Wing-covers are black and each with two narrow white lines. The front line link from scutellum to mid wing edge. The hind line run across wings. On hind legs there are three large and two small spurs on one edge and two on another. The abdomen is red in colour.

They are attended by different species of ants.

Those ants around them come for their excretion of 'honey-dew', which is the excess sugar that the treehoppers do not need. The presence of ants discourage predators, this becomes a kind of protection from the ants.

In the above first picture, there are the white substance attached on the stem. We are not sure if this is the eggs laid by the Gum-leafhopper.

They are quite common in Brisbane eucalypts forests.
