Lump worry!

[colin haris]

Hi All

I am hoping you guys can calm my nerves. I noticed this lump yesterday on my female rosea. As you can see she has a large rump which I am hoping is because she is gravid.
Hopefully it’s just a lump she has acquired due to dragging her big butt about, but I am worried it could be serious. It looks like a blood blister or a mole would look on us.
Does anyone have any ideas as to what it is?

Hi Colin.
It's hard to tell exactly what it is from the pictures, but it kinda of looks like an abraison of some sort.
I had an A geniculata that had a huge abdomen that had an abraison on each side. It went away after a molt. I would guess it came from it having a big abdomen, and it's legs rubbing against it (it was like that when I got it).

Hi Colin

I've had a Lasiodora difficillis with a mark on the rear of her abdomen for quite a while now, this doesn't look that dissimilar to your spiders mark (although a little bigger)
It doesn't seem to have been a problem to her so far, although i'm wondering what may arise when she decides to moult (possibility of sticking in this area etc etc)

From what i can see in your images, it looks like a small puncture wound (or as Chris has said...an abrasion) that has healed over.

My guess is that she'll be ok, obviously keep an eye on it to make sure it doesn't get bigger or start weeping, just watch her when moulting to make sure it doesnt open up again with her new exo being quite soft.

Thanks for the advice guys. I am keeping a close eye on her all the time at the moment as I am hoping to see an eggsac from her soon.
A little curly haired of mine had a small blister appear on his/her abdomen a while back but a molt got rid of that with no problems. I suppose I was just a little suprised at how perfectly round, small and dark this particular lump was.
Anyway at least you have eased my worries a litttle, thanks again!
