Avicularia variegata

Meet the Avicularia variegata, a unique tarantula from South America. While many once thought it was just a type of Pink Toe Tarantula, it’s actually its own special species. Learn interesting facts about this spider here.

Scientific Classification

Avicularia variegata

Physical Description and Identification

Adults

  • Size: Adult Avicularia variegata can reach a leg span of 12-15 cm.
  • Color: There are two morphs of this spider. One has a pink sheen, covered with reddish-brown setae. The other morph has a gold carapace with a greenish glow with yellow rings on the legs.
  • Other Characteristic Features: They have urticating hairs on their legs to deter intruders.

Eggs

Females lay their eggs inside a sac made of webbing.

Spiderlings

The immature spiderlings will initially stay close to their mother until they are old enough to fend for themselves.

The Web

As these spiders ambush any potential prey, they do not use webbing for this purpose. However, they construct retreats made of silk threads on the branches of trees.

Are Avicularia variegata Tarantulas Venomous?

Yes, Avicularia variegata tarantulas have venom, like most tarantulas. However, their venom is usually not harmful to humans.

Can Avicularia variegata Tarantulas Bite?

Yes, Avicularia variegata tarantulas can bite if they feel threatened, but bites are rare. If bitten, it might cause some discomfort, similar to a bee sting.

Ecological Importance and Behavior of Avicularia variegata

The Avicularia variegata plays a crucial role in the control of insect populations within its ecosystem. Their predatory behavior aids in maintaining a balanced food web, ensuring that no single insect species dominates the environment. This balance is vital for the health of mature and secondary forests where these tarantulas reside.

Natural Predators: Despite their defensive capabilities, Avicularia variegata tarantulas are not without natural threats. Birds, larger mammals, and even other species of spiders are known to prey upon them. Their arboreal lifestyle, however, provides a degree of protection as they navigate the higher canopies of the rainforest.

Prey-Predator Dynamics: Avicularia variegata primarily feeds on a variety of insects, which they capture through ambush. This dynamic is essential for the ecosystem, as it controls insect populations and contributes to the dispersal of energy and nutrients within the food chain.

Relationship with Humans: Humans have a complex relationship with the Avicularia variegata. While some people keep them as pets, fascinated by their striking appearance and docile nature, others may have an inherent fear of tarantulas. However, their presence is generally beneficial as they help control pests naturally.
