Phidippus ardens, known as the Widow Jumping Spider, is a striking, large-bodied jumper native to the USA.
 
This charismatic species is often mistaken for black widows due to its two vivid red stripes on the abdomen, but it belongs to the jumping spider family and is entirely harmless to humans. Spiderlings hatch large and feed readily on hydei fruit flies, making them relatively easy to rear. Adults boast metallic green chelicerae, and mature males develop a blood-red abdomen with black-and-white striped legs, adding to their dramatic appearance. Arboreal by nature, they thrive in warm, humid conditions and are popular among keepers for their bold looks and engaging behavior.
