There are two common and three much less common species of Araniella in the UK. The common ones, A. cucurbitina and A. opisthographa have a very similar appearance, being about 6mm long (females), green in colour, with a small red spot above the spinnerets. A series of black spots on the abdomen can also be seen in the photo.
