I finally got my first good look at my versi since it molted over a month ago... It was about 1.5 inches pre molt and is now 2.5 or so (leg span, guesstimates). It went from blue, to blue with a few longer reddish bristles on the opithisoma, to now having the blue/green prosoma and lots of longer reddish bristles on the opithisoma as well as some on the legs.
here's a snippet of a molt record i've kept of one of my versicolors..hope it helps:
(when it was 2" it was pretty much pure blue-spiderling coloration.)
August 7- molted 11:30pm from 2" to 2.55 inches. still showing mostly juvenile colors, but some red on abdomen, and green tinted carapace.
October 12- molted out to 74mm legspan, to mostly adult coloration
it's next molt its colors were the same, just more bright than the previous molt.
