Bronze jumping spider: Description.

Male Bronze jumping spiders of this species have a dark cephalothorax with white bands along the sides and elongated chelicerae protruding from the front. The abdomen is lighter in color than the head, featuring lateral stripes again of white.

Females share similar traits but lack these distinctive longitudinal stripes, showing short white lines near their heads and an arrangement of longer dorsal spots on their abdomens. In size, females range between 6-8mm, while males are typically 5-7mm long.

Bronze jumping spider: Behavior.

The Bronze jumping spider is a small but remarkable species – its bronze-brown coloring often causes it to be overlooked, even though these spiders can be easily spotted indoors and outdoors. From rustic backyards to bustling cities, this arachnid can usually crawl on building exteriors or interiors in the fall. In addition, some individuals may aggregate during autumn months so that they may hunker down for winter beneath dead tree bark.

Bronze Jumping spiders: Diet

The Bronze jumping spider is an opportunistic feeder, devouring whatever its impressive chelicerae can grasp. Their ravenous appetites range from crickets and worms to butterflies and leafhoppers; not even pesky fruit flies or bees are safe! It’s hard to believe that this vibrant arachnid thrives on a wide variety of small insects.
