What is a group of Spiders called?

A group of spiders is commonly called a Cluster. Other collective nouns you may see include Clutter and Swarm.

Collective nouns are words used to describe a group of individuals or objects. When it comes to spiders, there are a few collective nouns that can be used to describe gatherings or collections of these arachnids. 1. Cluster: A cluster of spiders refers to a group or gathering of spiders that have come together. It implies that these different spiders are found close to each other, often in the same vicinity or location. 2. Nest: Nest is another collective noun used to describe a collection of spiders. It suggests that these spiders have chosen a specific location or site as their habitat, creating a communal living arrangement reminiscent of a nest. 3. Cobweb: Although commonly associated with a spider's web, cobweb can also be a term used to describe a crisscrossing collection of interconnected spiders and their webs. It highlights the intricate, interconnected nature of these spider habitats. 4. Cluster-web: Cluster-web refers to a specific spider species known for creating complex webs layered with different levels and chambers. It can also be used to describe groups of these particular spiders, highlighting their expertise in constructing elaborate structures together. 5. Army: While not as common to associate spiders with an 'army,' this collective noun is used to emphasize a large, organized group of spiders moving and acting together. It suggests both purpose and unity, as well as gives a sense of magnified presence when referring to them. 6. Swarm: Similar to army, swarm is a collective noun often associated with insects but can also be applied to spiders to describe a large number of attentive and energetic spiders. This plural noun brings to mind a group of spiders that are quickly and actively moving about, potentially following a collective purpose. Please note that none of these collective nouns exclusively represent specific spider species, but rather describe groupings, gatherings, or behaviors of spiders in general.
