Araneus diadematus, commonly known as the European garden spider, is a species of orb-weaving spider found throughout Europe and parts of Asia. It is easily recognizable by its distinctive white cross pattern on its back, which helps it blend into its surroundings. These spiders typically build large, circular webs in gardens, forests, and fields, where they catch various flying insects. This species is not harmful to humans and plays a vital role in controlling pest populations. Araneus diadematus is most active during the warmer months, and females are larger than males, often reaching up to 20 millimeters in body length.
