The green huntsman spider (Micrommata virescens) is a spider with a palearctic distribution, of the huntsman spider (Sparassidae) family.[1] M. virescens is a species occurring naturally in Northern and Central Europe, including Denmark.[2]

It does not build a web, and hunts insects in green vegetation, where it is well camouflaged.

The green coloration is due to the bilin micromatabilin[3] and its conjugates in haemolymph, interstitial tissues and the yolk of oocytes.[4] A bite from this spider on a human may cause some local swelling and a little bit of pain, and would be gone within 2 days. [5]
