There is a funnel-web spider in Australia, that is considered poisonous. It has a reasonably close cousin in New Zealand, which looks very similar, and though it will bite it is not poisonous to humans.
The NZ ones are impressive size, with a flat body up to 3 cm in diameter, and long stout legs. They also live under logs and firewood stacks.
Spider webs themselves are not poisonous to humans. However, some spiders that create the webs may be venomous and can bite, causing harm to humans.
Do you mean "spiders that make cobwebs"? Do you mean "poisonous" (like hemlock tea) or venomous (like cobra venom)? The word "cob" in "cobweb" just meant "spider." So a cobweb is just a spider web. Not all spiders are venomous. No spiders are known to be poisonous. Since black widows make webs, some "cob spiders" are highly venomous.
When ever they want to . But some do not make webs
Spiders are eight legged creatures that make spider webs and eat insects for living. Most spiders aren't poisonous, and no poisonous spider will attack without reason. Spiders are about the size of a bead. That's small! Furthermore, spiders can be found anywhere. You also might see spider webs without their hosts. These are called cobwebs. Spiders are fascinating creatures. They belong in a group called arachnids. It is fascinating to explore the world of spiders if they weren't creepy.
Spiders make unique webs because they do not want other spiders coming into their webs. They have a unique shape, design, and scent to keep other away.
