My A avic just molted and as she's almost finished hardening her fangs I noticed this new brown spot on her upper abdomen linking to her thorax. I don't know what this is, any advice or help?

That is the pedicle! It can be more visible on some Ts more than others for a number of reasons but Its a perfectly normal part of a tarantulas anatomy that connects the abdomen to the cephalothorax.

Edit: on closer look, do you mean the light brown spot off to the left? The picture isn't super clear.

That's their anatomy. Why didn't you look up their anatomy first?? Help yourself to some knowledge by reading up on on your animals, it will help your BP. ;)

It's never been on her before and not on the other side is my worry I've had her for years and she's never had it

Agreed. I used to explain it. I stopped generally. I learned info from researching here, and learning unexpected useful bits of info unrelated to the original topic I searched for within various threads.

Too many people see something "strange" and immediately post, they put all caps etc as if an atom bomb went off. Totally unnecessary for 99.9% of the questions.

When I saw something "unusual" I searched a lot before posting, not saying the OP didn't, who knows. It can be challenging to find certain things that are visual in nature, and you don't know how to describe it. I get it.

Google for images for that part of their anatomy. I can tell you tons of people ask about this part because it looks different than the rest of their body surface, The same applies to their lungs. Do you know how many people tell us they don't know what these "weird spots" are that they have NEVER seen before are-- TOO MANY :banghead: :rolleyes: :rofl: The same applies to the pedicle. Humans have MANY pedicles!

Now if you aren't referring to your Ts pedicle that's another story. Then all the above is wrong from my side.

Your image isn't the best, but from my eyes I see pedicle, it's a bit blurry for me. But the pedicle has been there since the dawn of time.

Part of the issue is I've never seen it on her before and I've had her for years. It's also only on the one side.

It's likely because she molted and it became bigger and you just noticed it.
I'm just worried as before her a had a juvenile thay died and even after a couple years I want to keep my girl around

It's closer to her side I thought pedicles are more dorsal 20210502_131303.jpg

I've looked up tons of images on Google and none have what's on her side which is why I'm worried

It looks like a cyst from images just in its early stage

Well if it is a molt the usual thing that happens is they molt and they are fine the issue is mine is a seven inch female so she probably won't molt again....

Thank you for the second pic. This is more helpful than the first. Now that I can see this better, it appears there's a bald spot on the left side of the abdomen in that image. I can't say for sure, but I can see how one may think it's a cyst. It would be easier if I had the T in front of my, I'm sorry. Or a closeup image in focus.

It may be one, it certainly isn't the pedicle. IF it is, slow down the rate of feeding. I've had a cyst on my emilia, she was a young adult when she had it. It took about 4 molts for it to go away (that's a few years). During that time I didn't feed her as frequently as I do as they put on a lot of mass.

Avics not as much mass of course, but certainly IMO the same "rule" applies, slow down feeding. Hope for the best.

The issue is she's seven inches and probably wont molt again for a very long time so I don't know whay to do. I was ironically going to try and feed her more to try and force a molt to try and eliminate the cyst. But I don't know what to do and I'm scared for my girl

I’m quite new to tarantula keeping, but I believe tarantulas continue to molt even after their adult stage. They don’t have a predetermined number of molts the way some true spiders do. They will certainly molt much slower (my adult B hamorii molts about once a year).

Mine molts maybe once a year from my experience but she just had her yearly molt

There's nothing you can do that I'm aware of. We call them cysts, but honestly never seen a biopsy to determine if they are fluid filled like a true cyst would be in humans etc. I can't think of anything that would cause their exoskeleton to bulge out other than fluid over time, I'm not an arachnologist.

The general thought is to reduce their feeding so the abdomen doesn't balloon in size, causing the cyst to remain its size, and not get larger if fed a lot. I wouldn't increase feeding.

Ok I'll try to feed her every two maybe three weeks does this sound good?

I would do something like that. Don’t plump her up. She’ll molt at some point when ready.

7” is a nice size female M6! I’ve only had males hah.

It's a cyst or some other form of growth, it might go away with subsequent moults but it might get worse, nothing you can do except try not to overfeed (this will reduce the likelihood of the cyst/growth causing a rupture).
