Araniella cucurbitina (one of two species called the "cucumber green spider") is a spider of the Araneidae family. Females grow up to 8 mm, males only up to 5 mm. The spider is mainly found on forest clearings, where it weaves its orb-web between leaves and flowers. These webs are only about 10 cm in diameter. This spider does not use a hideout, because it is camouflaged by its green colour. Adult spiders first show this color in spring.
