    Update (post 3, 19): 3/2/16 She molted within the last week. The cyst is still present and looks white, scleritized and about the same size as it has always been. I was able to remove the molt and could examine the intact area of interest. There is a quite small amount of white that may be shed book lung but it is mostly gone as opposed to the other three that shed out normally. Where the book lung should be you see an outline and depression, and there is a thin membrane in the area, with a few red particles near the posterior edge. So maybe the old book lung is being retained, or not developing. But I'm no expert on the shedding of organs in tarantulas.

    Molted again on 5-17 and is doing ok still. Abdomen is still oddly shaped, resembling a jelly bean. Finally, a name for this one!

    I'm going to start gathering the photos I have and fill out the survey when I get home from work but I was just wondering if there is anyone that I can speak to about what exactly it is I need to do to give my Avic the best shot at survival.

    Update from Post #18

    My B. vagans had its ultimate molt and as a MM, the cysts vanished and it lived about 1 1/2yrs post molt. I didn't change anything and I still don't know what those cysts were caused by...

    7) If it recovered, did it ever show signs of another occurrence of Cyst/lesion/growth
    No

    n/a

    9) Where sibling/parents of the affected spider in you care? Did they show similar symptoms?
    No, n/a

    Yes, but no contact

    13) If the specimen recovered, please provide info on how the care regimen was changed or what was done to aid recovery.
    I moved her to a tank with less vertical space so she couldn't fall and rupture the cyst. It cleared up on its own within 2-3 instars without recurrence.

    On May 6, 2017, I acquired a Brachypelma albiceps juvenile female - approximately 3". I received her in her enclosure which was very dirty and didn't seem to have been cleaned for a long time. She had less than an inch of substrate and no water dish or hide (they could have been removed before she was handed over to me) and the substrate was very dry and caked. Previous owner said that she last moulted in January or February 2017.
    She was very dull and dirty looking, and very lethargic, so I thought that she might be starting to go into pre-moult. On May 12 2017, I noticed her sitting over her water dish for many hours - probably up to a day. She moved off herself, I did not move her. On May 15, I noticed that she was sitting grasping a lot of substrate in her fangs. Because I experienced the same with one of my elderly tarantulas shortly before she died, it bothered me. I decided to have a quick look at her as well as to try to offer her some water manually. While I was doing that, I noticed that her sternum was bald and looked to have a growth on it.
    Although I have offered her a medium cricket, or meal worm, every weekend since I got her - she has never eaten with me.

    1) Temperature range.
    Room temperature - around 24C/75F constantly.
    2) Humidity range.
    Low ambient humidity, but her substrate was fairly new and not completely dried out. I had been overflowing the water dish, and about 25% of the enclosure, because I thought she might be in pre-moult and her previous enclosure had zero moisture in it. I prefer to inject the water under the surface instead of wetting the surface for drier species. I never mist.
    3) Was a clean water bowl available at all times?(Yes/No)
    Since May 6, 2017, yes.
    4) Feeder item background information(Species and what the food items ate/drank).
    Offered both medium crickets and medium meal worms with no success.
    5) When did the first signs of any Cyst/lesion/growth appear?
    May 15, 2017.
    6) Did the specimen ever recover?
    TBD
    7) If it recovered, did it ever show signs of another occurrence of Cyst/lesion/growth
    TBD
    8) If the specimen died while still displaying signs of cyst/lesion/growth, How long after the first signs did it live until passing?
    TBD
    9) Where sibling/parents of the affected spider in you care? Did they show similar symptoms?
    Unknown.
    10) Prior to the specimen displaying any signs of ill health, was there any major changes to its environment/spider room/care?
    She was picked up about an hour away from me on May 6 and transferred into a new enclosure on the same day. Nothing since.
    11) Where there any pesticides spray in or around your home?
    No.
    12) Do you own any cats or dogs?
    Yes, but they do not have access to her. The cats are indoor only and are not treated with any anti-parasitic medications. Neither have I been in contact with animals who have.
    13) If the specimen recovered, please provide info on how the care regimen was changed or what was done to aid recovery.
    TBD
