Candy-striped spider, still on guard under the two hazel leaves stuck together by the web-ball holding what I presume are her eggs. She is still keeping steadfastly on guard, though in a somewhat different position every time I look. But no signs that I have been able to spot of any changes in the appearance of the web.
UPDATE: Since these pictures were taken, the female has gone, with still no sign of developments in the web complex. She may have given the whole thing up as a bad job, or have been spotted by a predator.
