Ultimate Molt?

Hey guys newbie question lng about Ultimate molt of final molt

How do you guys tell if you Tarantula is already in its Ultimate Molt stage?
does Ultimate molt stage apply to Females?
What are some signs that its already Ultimate molt?

Ultimate molt is most commonly used for Male T's that are close to their adult stage, kung baga it is their final molt - the line ends their. But then others also use it for female T's that are going to adulthood, but then syempre females live longer than MM T's. Just like any molt, same signs parin ang lumilitaw sa T if its about to molt. Although in my experience with males that are in to their ultimate molt, usually longer ang pre-molt stage niya - going on for 3-4 months until molting. Telling a T is in its ultimate molt stage is really indefinite, because there are males that mature fast kaya paminsan ilang "s lang MM na sila while other grow bigger before they mature. Hope this helps heheheh

hi. it's easier to tell for males because their tivial hooks come out after their ultimate molt. the tivial hooks appear behind the 2 front legs. males usually develop them within 2-3 yrs. depends on how often you feed them. for females i'm not really sure how fast they reach ultimate molt. probably around 3 yrs too.

@earl.chan, thanks sir hehe its helps so there is really no general rule to go with to know whether a T is in its ultimate molt right sir?

@tubigpa, i see sir ummm i've read that not every specie can have tibial hooks po b? i have 2 males a Smithi and Parahybana will those specie develop tivial hooks?

i got concerned because i bought Male T's and don't know how to tell if they're going to reach Ultimate molt already,.. unlike scorpions that have a track record of instars,.. i find it difficult to know whether its a mature mate or mature female haha sorry newbie questions

The following tarantula genera DO NOT have tibial hooks as mature males:

Annandaliella Hirst, 1909 (Selenogyrinae)
Anoploscelus Pocock, 1897 (Eumenophorinae)
Augacephalus Gallon, 2002 (in part): A. junodi (Simon, 1904) (Harpactirinae)
Chilobrachys Karsch, 1891 (Selenocosmiinae)
Citharischius Pocock, 1900 (Eumenophorinae)
Coremiocnemis Simon, 1892 (Selenocosmiinae)
Euphrictus Hirst, 1908 (Selenogyrinae)
Heteroscodra Pocock, 1899 (Stromatopelminae)
Heterothele Karsch, 1879 (Ischnocolinae)
Hysterocrates Simon, 1892 (Eumenophorinae)
Ischnocolus Ausserer, 1871 (Ischnocolinae)
Lyrognathus Pocock, 1895 (Selenocosmiinae)
Metriopelma Becker, 1878 (Theraphosinae)
Nhandu Lucas, 1981 (in part): N. carapoensis Lucas, 1981 (Theraphosinae)
Orphnaecus Simon, 1892 (Selenocosmiinae)
Pachistopelma Pocock, 1901 (shield of spines only) (Aviculariinae)
Phlogiellus Pocock, 1897 (Selenocosmiinae)
Phoneyusa Karsch, 1884 (Eumenophorinae)
Phormingochilus Pocock, 1895 (Ornithoctoninae)
Plesiophrictus Pocock, 1899 (in part): some males may possess tibial apophyses (Ischnocolinae)
Poecilotheria Simon, 1885 (Selenocosmiinae)
Selenocosmia Ausserer, 1871 (Selenocosmiinae)
Selenotholus Hogg, 1902 (Selenocosmiinae)
Selenotypus Pocock, 1897 (Selenocosmiinae)
Sericopelma Ausserer, 1875 (Theraphosinae)
Stromatopelma Karsch, 1881 (Stromatopelminae)
Theraphosa Thorell, 1870 (in part): T. blondi (Latreille, 1804) (Theraphosinae)
Thrigmopoeus Pocock, 1899 (Thrigmopoeinae)
Xenodendrophila Gallon, 2003 (Stromatopelminae).

Note: There are certain species that while the mature males do have tibial hooks, the hooks are rather small and may not be as noticeable as our image above. For example: Avicularia

Yes sir. Nagkaroon na ako pareho ng mature male smithi & parahybana. both of them had hooks when they matured. No worries.. okay nga questions para matuto tayo lahat. para ma-share ang 5 cents worth of what we know. saka we can stand corrected if may mali masabi para hindi ma mis-inform ang mga hobbyists lalo na newbies.

query was answered. closing the thread mga pogi.
