Binomial name
Enoplognatha ovata (Clerck, 1757)

It is native to Europe and has also been introduced to North America. It is notably found in Lithuania.[1]

This spider, reaching a length of 6 mm (excluding legs), has translucent legs and the globular abdomen is extremely variable in colour and pattern: the background colour is white, cream or green and can be marked with a row of dark spots, a broad red stripe or with two red stripes in a v-shape. Despite its small size, this is a formidable predator which can prey on insects many times its size. The female deposits its eggs in a white sac and after several days the sac gradually changes colour to a blue/grey. This is secreted within a rolled-up leaf fastened with silk and the female guards it until the eggs hatch.
