Hi again so I took everyone's advice from my last post and now I have run into another question I went to feed my T today and noticed he has a bald spot as if he's been throwing hairs. Could this possibly be a sign of him going into molt? I can't think of anything that would make him feel like he needs to defend himself.

NW terrestrial species often spread their UrS around near the entrance and inside their burrow as a means of passive defense. There doesn't have to be an apparent threat for them to do this - they're paranoid. Lol.

its an unreliable sign imo since there are other reasons that can cause it to do that my b boehmei kicks hairs over anytihngopening the lid/lifting its cage etc,use the search function to learn about pre molt signs. food refusal /butt getting blacker etc.your t also provided you with an easier way to know and guess at how close your t is to a molt with that bald spot. good luck

No some Ts do flick hairs often

It helps that its bald though: you can see color of skin changing as it gets close to molting.

say a beige abdo has black urs. The urs all gone. The adbo stays beige. Then, as it darkens, it gets a uniform greyish black colors. And when its ready to pop, its very shiny. It could still have urs and molt.

and this is mostly observable on slings that dont have coloration like d pentaloris. Those ones, can fade coloring instead.

Ts use their hairs sometimes just because. But it also a passive defence for both when they moult, when they set up their burrow, when they eat etc...
There's a breakdown somewhere on this forum of the different types of hairs and what they're optimized to do.
Throwing hairs can just happen because something spooked the spider.
I will say that since they run on instinct, they react to stimulai. So if conditions persist their behavior becomes much more predictable. You noticed a change in behavior(throwing hairs) and that's good. You should pay attention after this moult to see if it does it again. It very well could be a reliable indicator for YOUR tarantula. Then again, it very well could not be.

it is definitely something to think on. Its not always the case, but it can be a factor.

when my brachypelma emilias settled in, and molted, i did not seen them kick much anymore, nor balding. I know it will happen again, and the bald patch can get better. But now that my tarantulas are comfortable in a setup that mimics their habitat, they are so much calmer.

you’ll never see me try to pick them up though. Emilias are little balls of spice. I like them in their enclosure. As far away from my face as possible.
