Hemiptera
- This page contains pictures and information about Leafhoppers in family Cicadellidae
that we found in the Brisbane area,
Queensland, Australia.
-
 -
- Leafhoppers are tent-shaped insects which resemble
small cicadas. Some species are green in colour, some are brown while
some are black with white, red or creamy-yellow markings. The nymphal stages resemble the adults but wings are absent.
Most leafhopper species live in colonies
of mixed stages while few other species are solitary.
-
- Leafhoppers are small, plants
feeding insects ranging in colour from green, through yellow-green to brown.
They can be found on tree trunks, stems and leaves. They feed by sucking the sap
of plants.

Attended by ants
-
- All
of them jump, so their name hoppers. Some of their adults are active flyers.
-
- Several species are
attended by ants which collect the sugary secretions (honeydew) produced by
the leafhoppers. An airborne fungal disease – sooty mould
– is sometimes associated with the honeydew.

 Subfamily Ledrinae -
Flat-headed Leafhoppers- Species in subfamily
Ledrinae are relatively large. They are usually brown or green in
colours. Most of them have a front-extended flat head. Their larvae are very
flattened. They can be found on tree trunk or on leave of Eucalyptus.
-
-
-
 Subfamily Cicadellinae- The Cicadellinae species are usually
medium sized and elongate insects.
-
-
-
-
 Subfamily Tartessinae- The Tartessinae are small to medium sized leafhoppers with a distinctly
heart-shaped pronotum.

-
-
 Subfamily Penthimiinae- Penthimiines are round squat insects. Adults have front wings reaching just to the end of the abdomen and usually slightly
overlapping.
-
-
-
 Subfamily Eurymelinae -
Gum-leafhoppers- Once this group of Gum Treehopper species are classified as the family
Eurymelidae. They are now classified as a subfamily of the Cicadellidae.
Many species in this family are brightly coloured. Their head is relatively
wide and flat with ocelli in the front. They often stay in groups
feeding on young stems of eucalypt.
