General Species Information:
Found on Ellura (in the Murray Mallee, SA), the Adelaide Hills and elsewhere
1st Live Photo on-line:
~15 to ~16mm head to tail & each antenna is ~22mm long.
Marie found S1 drowning in a bird bath.
We were surprised at the difference in colour between wet & dry. After a day in an insect box came back to life and started walking around, so was released.
Notice the very hairy antennae.
In terms of colour, it's an odd mix of chestnut to silver grey patches.
The spine/horn/tubercle placement is important diagnostically, as are it's antennae & eye shape.
These beetles have so many intricate shapes to them. Tubercle can be invisible in one shot and with a bit of angle adjustment suddenly stand out. So have added many shots of the Tubercles, with S2, from slightly different angles.
