Weird huntsman behaviour

I have a huntsman which is still fairly juvenile and around two inches in leg span when stretched out.

I keep her on the coffee table next to the sofa and I noticed a strange sound which I could hear above the television.

She's drumming/vibrating her front legs (not her palps) really quickly and firmly against the container sides and it's a fast staccato drumming around the same speed as a cats purr. It's also noticeably loud.

She'll then get very active and start running everywhere, then stop again, start the drumming. She's also not in the classic flattened, legs bent forwards crab stance typical to huntsmans, instead she has her legs bent upwards.

Another thing is that she's a frequent bather and is always cleaning herself by running her legs through her fangs. However, she is now doing something strange that looks like bathing but instead of running her legs through her fangs she's rubbing her legs up against her butt, right where her silk comes out.

In the midst of this she is also occasionally rubbing the underside of her body up against the perspects with legs on one side out straight and flat while dragging her self sideways with her other legs. Do huntsmans scent mark? Because it almost looks like this is what she's doing.

She had a molt around three weeks ago and has been gorging herself on fruit flies. Surely she's not getting ready for another molt already?

She (I'm assuming it's a female due to the long skinny palps) is defintely acting markedly strange and I've not observed her like this before.

I just realised she's doing the drumming with all of her legs, one at a time, not just the front ones. And the dip and sway/dragging one side of the legs and body against the edges of the container thing appears to be intensifying.

I'm torn between thinking she's sending a calling card out for a mate or she's getting ready for another molt.

Not sure about the drumming, maybe she's hearing vibrations from somewhere and decided to talk back, the other thing with her legs in her fangs etc, that sounds like normal grooming to me.

Could be a specific behavior to that particular species, know what type it is or have any images?

It's either holconia immanis or holconia insignis. I'll try and get a photo tonight when I get home.

I've contacted Museum Victoria (Australia) about the behaviour to see if they have any insight. They have a spider/bug enclosure and some experts there I think. Still waiting for a response. If I hear back I'll post what they say.

Possibly. The palps at the moment look female. But it's far from fully grown and I have no idea at what stage males reach sexual maturity and when their palps begin to develop the adult bulb shape.

The drumming and crazy behaviour has stopped and she's settled back into her normal placid behaviour. The museum I contacted has published my questions on their website which is promising. Still waiting for a response from them.

Her name is Persia. This is her a couple of weeks ago:

Can you get one of the top of the spider too? A lot of species in Australia look incredibly similar ventrally.

OP, could you please follow up with any info the museum comes up with? I've contacted North Chiang Mai University about this and the behavior is known. They have been investigating similar behavior which some think may be related to new pesticides being used. Another theory from one researcher is a maturing female 'spreading her wings', advertising her availability to mate.
