What Are Cobwebs? Where Do They Come From?

Cobwebs are not just dust accumulations but are abandoned spider webs. Spiders like the Therididae family create disorganized webs that become cobwebs when left behind. Other spiders, such as daddy long legs and orb weavers, also contribute to cobweb formation. Spider silk is strong and durable, allowing webs to persist even after spiders have moved on. These webs collect dust and pollen, making them visible as cobwebs. Despite their appearance, cobwebs are a testament to the resilience and complexity of spider silk.
