Furrow Orbweaver
Larinioides cornutusAlso known as Furrow Spider, Furrow Orb Spider, Foliate Spider
Furrow orbweavers craft circular, sticky webs near lakes, streams, and damp vegetation to catch emerging aquatic insects. During the day, they remain tucked inside a folded leaf or silken shelter at the edge of the structure, holding a signal line that vibrates when prey strikes. Their dark, scalloped abdominal markings resemble a framed leaf motif, providing excellent camouflage against weathered plant stems and wooden structures.
