This is a 4.5mm (0.2in) long green gem of a spider which I discovered a few of them on my climbing roses. Note the marble like patterning on the abdomen and the thin white marginal hairs. The males have a reddish-brown head and carapace, so this must be a female.
Seen spring through to autumn, on trees and bushes, often in suburban gardens and parks. Quite an uncommon species and tends to be regional, so very pleased with this find.
