Juvenile.

Araneus bradleyi is somewhat unusual, even among the orb weavers, in that individual specimens can vary drastically in both the colour and the pattern of the top of their abdomens. Some are almost entirely green, some have a green strip along each edge but yellow, orange and white in the centre, and others have no green at all but instead have the 'typical' pattern of warm colours. No one seems to know why this happens. Ron Atkinson.
