Definitive identification requires examination of genitalia under microscope. May be confused with other red-abdomened Phidippus species, but distribution in Idaho and California and coniferous forest at higher elevations provide additional context.

  • Phidippus audaxCommon widespread with similar jumping spider , but typically has bold black and white patterning rather than red and black; usually black with white or orange spots.
