Poecilotheria ornata sexual dimorphism

[Acheroraptor]

Those both look female to me, but there was a commenter on reddit who noted a male of his had the dark carapace markings until 5-6" DLS. There could be rare exceptions to what advan has documented here.

One of my friend said this dimorphism is related to time rather than size or number of molts. and when a keeper overfeeds their male, their trait will appear very late.

(and with a species which is extremely food-aggressive like ornata, it's very easy to do so. said friend told me to feed my ornatas daily unless they refuse food.)

though I'm not sure at all which is right....
