Black lace-weaver spider

False widow lookalike - black lace weaver (Amaurobius ferox)

The Black Lace-Weaver spider, scientifically known as Amaurobius ferox, is a distinctive arachnid species found in parts of Europe, including the United Kingdom and Ireland. As a member of the Amaurobiidae family, this spider is closely related to other lace weaver spiders, and it has its own unique characteristics that set it apart.

As its name suggests, the Black Lace-Weaver Spider is notable for its predominantly dark coloration. These spiders typically exhibit a deep brown to black body, which can vary slightly in shade among individuals. They have an elongated abdomen and long, thin legs, which give them a somewhat elegant and delicate appearance. The species is well adapted to its habitat, with features like strong, hook-like tarsi that aid in navigating their web and capturing prey.

Black Lace-Weaver Spiders are known for their intricate and funnel-shaped webs, which they construct in concealed locations such as cracks in walls, crevices, and corners of buildings, as well as under stones and in dense vegetation. These webs serve as effective traps for small insects and other arthropods, which make up the primary diet of these spiders.

In terms of behavior, Black Lace-Weaver Spiders are generally nocturnal, coming out at night to hunt and maintain their webs. They are not considered harmful to humans, as their venom is not potent enough to pose a significant threat. While they may resemble other spider species like the false widow (Steatoda nobilis) due to their dark coloration and shape, Black Lace-Weaver Spiders have their own distinct characteristics that make them a unique and fascinating part of the arachnid world.

Other false widow spider lookalikes in Ireland include the Lace-Weaver and the Missing Sector Orb Weaver.
