General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
Interesting how ones 1st instinct is to try and remove this tick. However, they are just as much a part of our native world as the shingleback.
There is very little information on ticks, etc, and without proper diagnostics we are just guessing that this is the species due to location & host; all engorged female ticks look pretty similar.
Not the tiny legs in these photos, they have 8; as do all arachnids.
