Common Jassid - Eurymela fenestrata 

Family Cicadellidae, Eurymelinae, Eurymelini    

This page contains pictures and information about Common Jassids that we found in the Brisbane area, Queensland, Australia.
 
Adult body length 15mm
 
Common Jassid is one of the largest size leafhopper in the Eurymelinae. We sometimes call them Large Gum-treehoppers, The adult is brown and dark violet under sunlight. There are some white spots on its wings. Nymph has the reddish-brown body with black markings.
 
Gum-leafhopper sometimes called Jassid because they were classified as family Jassidae before, then now the family Cicadellidae

End August 2009, we found many Common Jassids on young gum trees in a garden in Sinnamon Park. Most young gum trees there were infected. Adults and different instars stages of nymphs were found together on host plants. Besides some black moss, we did not see any others damages on those trees. The black moss is an airborne fungal disease, sooty mould (Fumago vagans), which is often associated with the honeydew that the leafhoppers excreted.

3rd, 4th and 5th instars
 
All leafhopper species have five instars and one adult stages. The above pictures show the 5th instars stage. They will become adults very soon. Usually they one generation per year.

As seen in the pictures there were some ants walking around them. They are attended by those ants. They excrete sugary 'honey dew' which is favoured by the ants.

2nd, 3rd, 4th instars and adults.
 
The Gum-leafhoppers are slow moving, usually run aside when disturbed. Unlike those in other hopper families, their nymphs cannot jump. However, adults are good jumper. They jump and fly away when touched.

Leafhoppers in genus Eurymela have only one spur on hind legs, which make them easily distinguished from other genus.

We found this Large Gum-leafhopper on gum leaf alone in Karawatha Forest during mid summer.
