I'm aware there are some undescribed species of Neosparassus which retain the green into adulthood. I'm not the best with Sparassids tho, @EathanDouglas could shed some light on this
Thanks Nate I’ve never seen a bright green “huntsman like” spider. It is small and perhaps a juvenile based on the following comment. The leaf it is on is a parsley leaf. Found in suburban veg garden.
The Australian Museum entry says “Some juvenile Neosparassus are bright green and in some undescribed species this colour persists as adults.”
