Mating behaviour

Linyphia triangularis lives in a wide range of habitats, where it may be found among low bushes and vegetation. It spins a horizontal sheet-web, and rests on the underside of the web for its prey.[5] Adults are active in the late summer and autumn.[1][5] The prey are snared by "barrage lines" above the web, and fall onto the horizontal sheet, where they are killed by L. triangularis, but are not wrapped in silk.[1]
