- 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.
-
 -
- Adult with brown eyes and powder pink abdomen. Their body colours vary quite a
bit between individuals.
-
 
 -
- 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.
