One Huntsman Spider and Many Mites ...and not just mites, according to one source, but mite larvae.
I had a couple of the dead trees that were still standing near the house cut down (and then cut up) for firewood.
When stacking the resulting logs, I found this Huntsman Spider complete with what appeared to be drops of resin so often seen dripping from injuries on gum trees.
Closer inspection revealed what I first thought were ticks.
I posted the photos on my flickr page and as so often happens, someone more knowledgeable than I did recognise them as mite larvae.
"Larval forms of these mites are parasitic on various other arthropods, for example harvestmen, but the adults are free-living predators.
...
The larvae bite a hole into the cuticula of the host and use a stylostome, which acts like a drinking straw, to drink body fluids dissolved tissues."
The Huntsman I understand to be a Sparassidae species (formerly Heteropodidae).
The mites, according to Wikipedia are Erythraeidae, a family of mites belonging to the Trombidiformes and are entirely new to me.
He's (she's?) watching closely.
Two days after placing the log with the spider still on it in a sheltered place UNDER the house, I found it entering the back door
:)
So far as I know it is now comfortably set up, inside here somewhere.

These are lovely photographs. I can see at least a baker's dozen of mites on that poor spider. Wonder what effect (if any) they're having on it?
