The Common Candy-striped Spider is one of the family of Comb-footed Spiders, also called Tangle-web Spiders.
It has three colour forms: two red stripes (as above, form redimita), a single red stripe (form ovata)
or very pale green with two rows of dark spots (form lineata, below). The front legs each have a black "knee"
(unlike the otherwise similar, recently split E. latimana).
The spiders are some 6mm long. They make loose, "tangled" webs to trap prey and hide their egg sacs in rolled leaves.
The spiders in the images above (centre and right with a dead Narrow-bordered 5-spot Burnet moth)
are thought to be the Enoplognatha latimana which doesn't have the black knee on the front legs.
