Family ACRIDIDAE
- This page contains pictures and information about the Gumleaf Grasshoppers in Genus Goniaea
that we found in the
Brisbane area, Queensland, Australia.
-
 -
- In Brisbane we found four species in this Genus. All of them are living on
ground level among the fallen gum leaves. All of them are brown in colour camouflage
as those dry leaves. Those four Gumleaf Grasshopper species looked very
similar and easily be confused. On pictures, we separated them by the shape
and colours their antenna, the hind legs and the carina (ridge on
thorax).
-
- They usually rest on ground among dry fallen leaves during the day. They
move up and feed on green leaves during the night.
-
-
- Mimetic Gumleaf Grasshopper
   - Goniaea opomaloides, adult body length 40mm,
nymph body length 10mm
- This is another species of grasshopper camouflages in dry gum leaf colour.
This species is smaller in size than the species compare with others in genus Goniaea. They feed
on gum leaves. When we were bushwalking in the Eucalyptus
forest on White Hill, Brisbane, we usually disturbed one or two of them
for every step we walked. They jumped and flied to about a meter away. They disappeared
in the dry gum leaves background. More pictures and information
please click here.

-
- Black-kneed Gumleaf Grasshopper
 
 - Goniaea carinata, body length 40mm
- Pictures taken in Mt Cotton during mid summer. When it flied, we saw its
bright yellow-orange hind wings. This grasshopper looked likes the Gumleaf
Grasshopper below but smaller in size and has longer antenna with white tips.

-
- Slender Gumleaf Grasshopper
-
 
- Goniaea vocans, adult body length
60mm, nymph body length 20mm
- The Slender Gumleaf Grasshopper is brown in colour, camouflages as a dry
gum leaf. We usually find them on the ground with the dry Gum tree
leaves when bushwalking in Eucalyptus forests. This species is easily
confused with the below species Gumleaf
Grasshopper Goniaea australasiae. Slender Gumleaf
Grasshopper has the carina, or the top edge of thorax, lower and less
pronounced, and has a distinct cut. More information and pictures can be
found here.
-
-
- Gumleaf Grasshopper
   - Goniaea australasiae, adult body length 50mm, nymph body length
15mm
- The Gum Leaf Grasshopper is brown in colour, camouflages as a dry gum
leaf. It has the prominent arched crest on thorax. The grasshoppers' hindwings
are orange in colour, can only be seen when it is flying. They are also known as Dead Leaf Grasshopper.
