Predation by Argyrodes trigonum on Linyphia triangularis, an Invasive Sheet-Web Weaver in Coastal Maine

Houser JD, Jennings DT, Jakob EM, University of Massachusetts, United States Department of Agriculture. 2005. Predation by Argyrodes trigonum on Linyphia triangularis, an Invasive Sheet-Web Weaver in Coastal Maine. The Journal of Arachnology. 33(1):193-195

A description of predation of a spider by another spider. The abstract: 'A female Argyrodes trigonum (Theridiidae) was observed feeding on a female Linyphia triangularis (Linyphiidae), a recently established European immigrant in Maine. Multiple observations of Argyrodes spiders inhabiting L. triangularis webs suggest that this invasive sheet-web weaver is not immune to web invasions, kleptoparasitism or predation by A. trigonum. The potential impacts of A. trigonum on the invasion dynamics of L. triangularis are unknown, but likely to be minimal.' /STUDY LOCATIONS:/ /SCHOODIC PENINSULA/
