Adult vs juvi, or varying between individuals, don't know?
General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills, the Riverland and elsewhere
These are a large grasshopper, but we have only managed to capture one adult, yesterday, to measure.
We've had 11 sightings over the last 11 years, in May, July, Aug, Sept & Nov; most being juvenile
The adult was ~31mm, with juveniles range from 21mm-31mm.
There is a near identical species, Adreppus fallax, which seems to have shorter wings. This is not normally a reliable characteristic to separate out grasshopper species. We will update this page as we learn more.
These have very distinctive antennae, being wide at the bottom narrowing to the tip. The segment lengths are very irregular.
Colours vary dramatically from grey through various shades of brown with or without dark/black banding on the sides. As can be seen, they camouflage very well and are difficult to find unless the move.
The inside legs are very colourful, starting with a blue splash at the hip joint, through maroon with or without white lateral dashes on the thigh, finalising in lavendar to purple shins & feet. To see these colours it's best to try and get your subject to climb something; it then stretches it's hind legs out and the colours become apparant. Typically the inside thigh is dark and looks black to the naked eye outside.
