This page contains pictures and information about Small Gum Tree Katydids that we found in the Brisbane area, Queensland, Australia.

- Male

- Female
- Also found this Bush Katydid on a gum tree on Jan 2011 on Daisy Hills.
- We found this green katydid nymph on a small tree top during winter in Toohey Forest on Aug 2003. It was moving slowing to escape from our disturb.
- Nymph length 20mm.
- The nymph was leaf-green in colour and did not have any marking or pattern on its body. Its wing buds were well development showing it could be the last instars, but relatively small in side. We will collect and raise one if we can find them again so that we will know how their adult look like.
