The linyphiid spider: Erigone atraToday James Harwood from the University of Kentucky visited OARDC and gave a seminar. He studies ecological interactions between generalist predators, and focuses on spiders and beetles.
The linyphiid spider is very small (a couple mm), and a very significant predator of both pests and beneficial species in agricultural settings. Dr. Harwood has done studies that have shown that these spiders actively construct their webs in areas with high prey density and that they are a valuable predator of aphids (since aphids often fall off of their host plants and are unable to escape the spider webs).
