Bronze Jumping Spider

Eris militaris

Also known as Bronze Jumper, Bronze Lake Jumper

Bronze jumping spiders stalk fields, orchards, and woodland edges across North America using remarkably sharp vision and precise leaps. Males display a dark metallic bronze head region framed by pale stripes, whereas females carry softer grayish-brown tones adorned with light spots across the abdomen. Active throughout the warmer months and into late autumn, these daytime predators perform an essential role controlling plant-damaging insects in native habitats and suburban gardens.
