This page contains pictures and information about 32-Spotted katydids that we found in the Brisbane area, Queensland, Australia. Spotted Katydids are also known as Mottled Katydids and Speckled Grasshopper.

Male, body length 65mm
The katydid's scientific name is Ephippitytha 32-guttataso and its the common name is 32-Spotted Katydid. However, the actual number of spots varies between individuals.

Notice the nymph's heavily armed legs. The Gum Leaf Katydid nymph looks very similar to them but their legs are not spiny.
