Spotted Orbweaver

Fascinating facts about the Spotted Orbweaver

• The orb-shaped web of the spotted orbweaver can span almost two feet across, forming a large wheel that hangs vertically from plants or man-made structures. Only females construct these webs, and they often place them near outdoor lights where flying insects gather. The broad diameter, up to 0.61 m, maximises the capture area for prey attracted by the illumination. This placement and size help the spider secure enough food each night.
• Each evening a female spotted orbweaver spins a fresh orb and then consumes the old one at dawn, reclaiming the silk proteins for the next construction. This nightly rebuild recycles nutrients, allowing the spider to maintain a strong web without expending extra resources. In areas where prey is abundant, the spiders tend to make webs with smaller radii, adjusting their effort to the local food supply. The behaviour ensures efficient hunting throughout the season.
• The spotted orbweaver's egg sac is a fluffy yellow bundle of silk tucked inside a rolled leaf, protecting a lenticular or spherical mass that measures between 5 and 12 mm across. Each sac may hold up to a thousand eggs, providing a substantial next generation. However, once the juveniles hatch they are vulnerable and are frequently preyed upon by mud-dauber wasps. This high predation pressure influences the spider's reproductive strategy.
• The spotted orbweaver normally hunts under cover of darkness, spinning its large wheel-shaped web at night to catch insects attracted to lights. As the season progresses into late summer and early autumn, females are often observed active in daylight, a shift that coincides with their peak visibility.
