Microlinyphia mandibulata (Emerton 1882)

An adult male Microlinyphia mandibulata, previously blogged about at Delicate Linyphiidae. This is a sheet-web weaver (Linyphiidae), so named for the shape of their webs. Four photos of this spider are now up at the gallery. (Photographed on 28 May, 2012 in Dinosaur Provincial Park.)
