Spiders

Orb weaver spider

The Orb-weaver spider belongs to the family Araneidae and is known for spinning large, wheel-shaped webs that are highly efficient for catching flying insects. These spiders come in a variety of colors and sizes, with some species displaying striking patterns and bright hues. The name “orb-weaver” comes from the symmetrical circular webs they construct, often rebuilt daily. They are mostly non-aggressive and play a vital ecological role in controlling insect populations, especially in gardens, forests, and wetlands.

Orb-weavers are generally nocturnal, hiding during the day and becoming active at dusk. They rely on vibrations in their silk threads to detect prey and use venom to immobilize it quickly. While they may appear intimidating due to their size or vibrant colors, orb-weaver spiders are harmless to humans and rarely bite unless provoked. Their web-building behavior is also a subject of scientific interest, as they use specialized silk types for different web sections, showcasing one of nature’s finest examples of biological engineering.
