Commonly known as St.Andrew's Cross spiders, these beautiful little orb weavers grace the foliage when warmer weather arrives, through summer and in to autumn. Famous for their bright abdominal markings and web decorations called stabilimentum - zig-zag ribbons of silk that form a full or partial cross through the centre of the orb web as seen here.
When threatened (perhaps in an attempt to confuse a predator), the spider responds either by dropping from the web or shaking it so vigorously that both spider and stabilimentum become a blur.
