Four-Spot Orbweaver

Fascinating facts about the Four-Spot Orbweaver

• The four-spot orb-weaver is found across a broad swathe of Eurasia, from Europe through Central Asia to the far-eastern reaches of the Kamchatka Peninsula and Japan. Within this range it favours gardens, wooded patches and any vegetated spot where it can stretch an orb-shaped web. Its webs are deliberately built close to the ground, a strategy that targets hopping insects such as tiny grasshoppers.
• Female four-spot orb-weavers can reach a body length of up to 17 mm, with the largest individuals usually being gravid, while males are roughly half that size. Both sexes share the same colour range, from brown through bright orange to green, and the females retain the four white abdominal spots throughout.
• Regardless of whether its body is brown, bright orange or green, every individual bears four distinct white spots on the abdomen. The spots are a constant field mark for identification.
• The female builds a more elaborate orb web that sits low to the ground, a placement that helps it snag hopping insects. Her structure includes a side-mounted, funnel-shaped retreat where she can shelter when the weather turns bad, and the web is smaller and nearer the surface than those of other orb-weavers.
• Adult females are capable of actively altering their body colour to blend with their surroundings. It takes roughly three days for a spider to develop a hue that matches the surface it rests on, providing effective camouflage. Their colour range is broad, spanning brown, bright orange and green, which they can fine-tune to the local background. This ability helps them avoid predators while remaining hidden in their low-lying webs.
