 Poecilothera regalis (Pocock, 1899)
Indian Ornamental Tree Spider aka Indian Ornamental Tarantula, Regal Pokey

Poecilotheria regalis is one of the most popular arboreal tarantulas. Their legspan sometimes exceeds 7 inches (18 cm).

The P. regalis' behavior parallels that of many arboreal spiders. In the wild the P. regalis live in holes of tall trees where they make asymmetric funnel webs. Their primary prey consists of various flying insects, which they seize in flight and paralyze. It is not unknown for the spiders of this genus to live communally when territory, i.e. number of holes per tree, is limited. 

These tend to be quite aggressive spiders. Although there has never been a recorded death from any tarantula bite, this species is considered to have a medically significant bite, with venom that may cause intense pain and severe illness in sensitive or vulverable individuals. They move rapidly and may attack when cornered.

The name Poecilotheria is derived from Greek &quot;poikilos&quot; - spotted and &quot;therion&quot; - wild beast. Regalis refers to &quot;royal&quot;. This whole genus of arboreal tarantulas exhibits an intricate fractal-like pattern on the abdomen.
