8-10-2025 EL HONDO, ALICANTE - ORBWEAVER SPIDER (Larinioides suspicax)


The Orbweaver Spider (Larinioides suspicax), also known as the Furrow Orb-Weaver or Flying Spider, is a Holartic orb-weaver spider found in temperate regions, particularly near water, where it builds orb webs on bridges and other man-made structures to catch flying insects. This nocturnal hunter is generally harmless to humans and is characterized by a large, oval abdomen, and a distinctive arrow-shaped pattern on its carapace. 

Appearance: They have large, oval, bulbous abdomens and can be black, grey, or red. A common feature is a lighter-shaded arrow pointing towards the cephalothorax on the carapace, and similar arrow patterns can be seen on the legs.

Size: Females are typically 6–14 mm long, and males are 5–9 mm, with leg spans from 18 to 35 mm.

Eyes: They possess a horizontal row of six eyes, with an additional pair above the center of the row.

Senses: While they lack ears, they can detect sound using specialized hairs on their legs. 

Location: Primarily found near water, such as rivers and lakes, and are frequently seen on bridges.

Webs: They construct intricate orb webs, which can be asymmetrical, especially in adults. The web structure may be more pronounced in heavier, older spiders.

Hunting: As skilled nocturnal predators, they hunt flying insects like flies and butterflies. Their webs are often positioned to capture prey over water bodies. 

Venom: Their venom is not dangerous to humans; a bite is unlikely to cause serious harm.

Diet: Their primary diet consists of smaller flying insects.
