Cybaeidae spiders
The family Cybaeidae belongs to the order Araneae. These spiders are commonly known for their funnel-web building behavior. They prefer damp environments, such as forest leaf litter, deep cracks in the soil, or areas near water bodies, which makes them inhabitants of the micro-environments within and surrounding agricultural lands.

Cybaeidae spiders
The biological life cycle of these spiders consists of an egg stage, several instar stages, and the adult stage. Development is highly dependent on environmental humidity and temperature. As strictly predatory organisms, they possess venom glands and chelicerae adapted for subduing prey, rather than feeding on plant matter.
Regarding their impact on crops, it is scientifically established that Cybaeidae are not pests. They do not consume plant tissues, sap, or fruits. Therefore, they pose no threat to agricultural productivity and should not be classified as a plant pest in any standard agronomic catalog.
Their role in the ecosystem is primarily that of a natural predator. They feed on various small arthropods, including many insects that are considered agricultural pests. By keeping the populations of these harmful invertebrates under control, they perform an essential ecosystem service within the field boundaries.
No protection measures are required against Cybaeidae; instead, integrated pest management (IPM) strategies should focus on their conservation. Avoiding broad-spectrum pesticides and maintaining hedge habitats helps sustain these natural enemies, which in turn reduces the need for chemical intervention against true crop pests.
