Poecilotheria striata

Poecilotheria striata, known as the Mysore Ornamental, hails from the forests of southern India—specifically the states of Karnataka and Tamil Nadu. In the wild, they hang out in tree hollows and crevices, usually several metres above ground. The region is tropical, experiencing warm temperatures and monsoonal rains. These spiders thrive in habitats with high humidity and lots of leafy cover to disappear into, which explains their love of tight, bark-lined spaces. In their native environment, they're masters of camouflage, blending handsomely into the mottled patterns of tree bark.

As adults, Poecilotheria striata are among the larger ornamental tarantulas, with females typically reaching 16–18 cm diagonal leg span, occasionally a smidgen more. Males are smaller and more slender, maxing out around 13–14 cm. Females are stocky and considerably more robust, while adult males develop those all-too-familiar 'leggy' looks when maturity arrives. Expect a lightning-fast spider once they hit adult size!

This species is classically arboreal, choosing the high life among tree trunks and branches. In captivity, Poecilotheria striata often scuttle vertically, weaving web tunnels behind bark or in cork rounds provided. Expect them to settle in high-up hides and dash into cover with unbridled enthusiasm at the slightest disturbance. Despite their skittish, reclusive nature, they'll occasionally be seen exploring—especially once the lights go down. They're not diggers but are ace climbers, so plan on giving them plenty of vertical real estate.

Females live gloriously long lives, easily reaching 12–15 years if well cared for. Males, as usual, get the short end of the stick; once mature, they generally last another 1–2 years, ever the hopeless romantics. Slower growth compared to some beginner species means you'll be enjoying their beauty for plenty of years—especially if your specimen turns out to be female!

Poecilotheria striata are fairly quick off the mark, growing from spiderling to adult in 3–4 years under optimal conditions and regular feeding. Good temperatures and a hearty meal schedule speed things up quite a bit. Like a garden local dog chasing a postie, the youngsters grow at a proper pace, though a cold or sparse period can slow them down.

Fast on their feet and occasionally dramatic, Poecilotheria striata are shy more than aggressive but will launch into warp speed retreat if startled. While they're less defensive than some cousins, they do have a hair-trigger startle response. Think of them as the introverts of the tarantula world—prefer peace and quiet, but can throw a proper wobbly if disturbed.

Aim for day temperatures between 22–26°C, with nights dipping no lower than 20°C. They're tropical types, and while they're tolerant of the odd British cool snap, you'll want to avoid long spells below room temperature. Supplemental heating may be helpful in autumn and winter—heat mats or ceramic bulbs work, so long as you don't fry your spider. Always monitor the temperature with a reliable thermometer, avoiding direct contact with the enclosure. Keep things comfortably toasty, just shy of 'I'm melting!'

Happy at 65–75% relative humidity, Poecilotheria striata will sulk if things get bone-dry. Regular misting (light, never sopping) keeps things right, and a water dish is absolutely non-negotiable—yes, even for slings. Good cross-ventilation is vital to avoid stuffy, stagnant conditions; a balance between airflow and humidity maintains a healthy spider and discourages unwanted mould. Think lush forest rather than the laundry airing cupboard.

Expect a 'peek-a-boo' relationship: they'll spend the day tucked in a webbed-up retreat, venturing out at dusk or when the dinner bell rings. Offering multiple hides and vertical structures can increase the chance of these beauties striking a pose in plain sight. At feeding time or during enclosure maintenance, they're apt to show themselves—but it's rarely a leisurely public appearance!

Poecilotheria striata are moderate webbers, constructing tidy tubular retreats along cork bark and in corners, but they're not likely to turn your enclosure into a Halloween display. Their webbing is practical—used mostly for lining hides and building snug retreat zones rather than dramatic display. Watching them weave a new lair is always a treat for the patient keeper.

Slings thrive on pre-killed or suitably tiny prey like fruit flies and small crickets. Juveniles and adults eagerly take down crickets, roaches, locusts and the occasional mealworm. Youngsters should be fed every 3–5 days; adults once a week or so. Poecilotheria striata have a strong feeding response—often leaping on food like it’s the last piece of cake at your nan’s birthday—but don’t overfeed. Remove uneaten prey to prevent stress or mould. Avoid wild-caught bugs: your spider is better off pest-free. Well-fed spiders grow faster, but always balance meals with proper humidity and temperature for healthy moults.

Tall, well-ventilated enclosures are essential. For adults, aim for 30cm tall by 20cm wide—we love Exo Terras or clear acrylic setups. Plenty of vertical bark pieces, cork tubes or artificial plants make them feel at home (and provide more peep show opportunities). Substrate should be about 5–10cm of coco fibre or peat; deep enough to retain humidity, but not for digging. Add a water dish big enough for soaking a tiny tarantula toe, tucked out of the way in case of bolting spiders. Don’t skimp on cross-ventilation—a stuffy setup invites disaster. Snug-fitting, secure lids are crucial for these agile escape artists.

Poecilotheria striata are best suited for intermediate to experienced keepers. Their speed, reactivity and potent venom don't make them ideal for first-timers. Confidence and quick reflexes come in handy, as does an appreciation for the occasional eight-legged magic act, where your spider vanishes the moment you open the lid.

Poecilotheria striata are the jewel of any hobbyist’s collection—stunning, sizeable and full of personality (if, by personality, you mean lightning reflexes and high drama). They reward keepers with beautiful mottled patterns, impressive growth and the thrill of spotting them mid-dash. They're best enjoyed at a respectful distance, so keep your hands out and your eyes peeled. If you love observing fascinating behaviours, appreciate a challenge, and don’t mind the odd disappearing act, the Mysore Ornamental will steal your heart—and possibly your nerves!
