Red Knee Tarantula

February 22, 2022

The red knee tarantula has a stout, wooly body that makes it look almost huggable. But this spider is big enough to feed on small animals and reptiles such as lizards and mice. The red-kneed tarantula also feeds on insects. The bodies of these spiders can grow up to 7.5 cm long, and their legs stretch across twice that length.


  • The red knee tarantula spider is potential prey for moths, birds, and lizards. 
  • To protect themselves from predators, they use their prickling hair to irritate the skin or even cause blindness. 
  • The red knee tarantula spits venom that causes a reaction like a bee sting when it lands on human skin. Like any bite, an allergy or severe reaction may follow red knee tarantula bites.


  • The male red knee tarantula is ready to mate when its molt is mature. These spiders mate during the rainy season, July and August.
  • The male red knee tarantula uses the front limbs to impregnate the female. She will retain his deposit until spring when she will form a silk mat.
  • Females lay 200 to 400 eggs that are wrapped in silk to create an egg sac. 
  • The sac is carried between fangs for up to 3 months until it hatches.


  • The red knee tarantula lives in burrows on earth when they can be safe from their predators. 
  • The safe habitat also makes preying easy as the red-kneed tarantula can jump out and ambush their prey.
