In the wild, this species lives in the dry regions of Venezuela where humidity is low and vegetation is sparse. It prefers open environments where it can create web structures between rocks, shrubs, and other surfaces.
Unlike burrowing tarantulas, the Greenbottle Blue relies heavily on webbing to create a secure living space. It uses silk to build tunnels, retreats, and hunting platforms. This behavior helps it adapt to harsh, dry climates where shelter options are limited. Replicating this environment in captivity is key to keeping the spider healthy and stress-free.
