Poecilotheria habitat size facts and classification

Posted by


Poecilotheria is a genus of the spider family Theraphosidae currently containing 14 or more species of arboreal tarantula, commonly known as tiger spiders. The genus is known for vivid color patterns, fast movement, and potent venom compared to other tarantulas. The genus is native to Sri Lanka and India. The name Poecilotheria is derived from Greek poikilos – spotted and therion – wild beast.

There is some information on breeding biology from captivity. Males mature between 12 and 18 months and die after the first breeding season or within 24 months.

Gabriel (2005) reports male maturity after 354 days and survival for up to 344 days after maturity. The Western Ghats males mature faster (12 months) than the Eastern Ghats males in captivity. However, in the wild the maturity time would probably prolong due to environmental conditions and prey availability.


Life expectancy: Females become up to 11-12 years old. Exceptions become 15 years old. Males are given a shorter lifetime of 3 years. Poecilotheria regalis lives in warm area.

Females mature between 5-7 years and live up to 10-12 years and produce on an average two clutches per year of 35-70 hatchlings per clutch in the wild.

Body length: 7-8cm.

Span width: 25cm.

Growth rate: Fast.

Life expectancy: Females become up to 11-12 years old. Males are given a shorter lifetime of 3 years. The spider probably won’t get this old in the wild.

Behavior: The Poecilotheria-genus is known to be as beautiful as potentially dangerous. The spider will try to flee at first. Persistent provocation can result in a bite. The bites are very painful and can result in hospitalization. Poecilotheria ornata is notorious to bite faster than any other species of the genus.


Population information is not available. This species is the most common of all Poecilotheria species and is encountered frequently in different habitats. Its population is healthy in natural vegetation; some individuals have been observed in teak plantations and in some degraded areas.

However, the individuals seen in degraded habitats are usually males that are migrating in search of females, hence this cannot be taken as a compatible habitat for this species. The populations are severely fragmented although the species has been found in more than 20 locations.
