Can any of our resident experts help me with this one? Photographed today in my conservatory in Wolverhampton, England.

Thanks, Nikita! Could you tell me (in layman's terms!) how you know it's a female? :)

Due to the shape of abdomen - wide laterally, but distinctly narrowed at apex.

Why has the C.tigrina in the attached pic got black stripes on the abdomen, but the first one I posted hasn't? :|
