I spotted another female heavy jumper (Hyllus diardi) a few days ago on a dry twig. I'm sure it is a female juvenile jumper. I am not just guessing, because as far as I know, adult females have thick hair. This one does not yet have thick hair; moreover, it is smaller than most adult heavy jumpers. I have no idea how long it takes for a juvenile heavy jumper to mature. What is certain is that I have seen many spiders of this type near the east coast of Lhokseumawe.
