About the species

Brazilian Blue (Lasiocyano sazimai) is a terrestrial tarantula endemic to Brazil, known primarily for the intense blue, iridescent colouration of the carapace and legs. The species occurs in the mountain areas of the Espinhaço range in the states of Bahia and Minas Gerais, in the characteristic campos rupestres habitats. Adults reach about 14–16 cm in leg span. Lasiocyano sazimai may use natural crevices and hides and periodically dig, and its colouration is particularly intense after a moult.

Care and behaviour

Lasiocyano sazimai is a terrestrial species that should be given a sufficiently thick layer of stable substrate. The spider may use a ready-made hide, natural crevices, or deepen a shelter itself, so the substrate should allow such behaviour.

A moderate moisture gradient works well in the enclosure: the lower substrate layers may remain slightly damp, while the surface should be able to dry. Constant access to fresh water and good ventilation help avoid both drying out and constantly humid, stuffy conditions.

The species may be calm during observation, but when startled it can move quickly. It usually shows a decisive feeding response and may periodically remain in view, making it a striking display species.

Good to know

Lasiocyano sazimai has urticating hairs and may use them when threatened. The species also has a limited natural range in the Brazilian Espinhaço mountains, and its wild populations are under pressure associated with habitat degradation and illegal collection. When purchasing, it is worth choosing captive-bred specimens from legal sources and avoiding animals of unclear origin.
