Araniella curcubitina

I took this photograph way back in July. The spider was on bracken and was busy wrapping up a small fly when this butterfly blundered into the web. It was touch and go for a while whether the butterfly would manage to escape, but as it fluttered its wings became stuck to the web, then the spider moved in and began wrapping it up. Although the spider has a red patch just above its spinnarets it is incredibly difficult to see unless it moves. As its fat, round body suggests it is in the orb-web family of spiders.
