Poecilotheria vittata

🔤 Taxonomy

Poecilotheria vittata is the currently accepted scientific name in the World Spider Catalog. Older hobby and literature material may discuss the same animal under related or disputed names, especially because Poecilotheria pederseni has been treated in connection with this species and P. vittata has also been compared with P. striata.

Useful names to recognize:

  • Poecilotheria vittata
  • Poecilotheria pederseni in older or synonymy discussions

English common names used in the hobby:

  • Ghost ornamental tarantula
  • Pedersen’s ornamental
  • Magam tiger spider

📌 Description

Poecilotheria vittata is a large arboreal Old World tarantula from South Asia. It is a fast, agile, tree-hole species with strong display value, but it is not a beginner tarantula and should not be handled. A keeper should be comfortable with secure arboreal enclosures, calm rehousing plans, and medically significant bite risk before buying one.

Adults usually reach about 18-20 cm legspan. Females become heavier and live much longer than mature males; males mature sooner, become slimmer, and often spend more time roaming.

The body pattern is grey, cream, black, and brown rather than the bright blue of P. metallica, but that muted pattern is part of the point: it provides excellent camouflage against bark. When settled, this species often rests flat on cork bark or inside a vertical retreat and may appear almost painted onto the surface.

Like other Poecilotheria, it is mainly a display spider. It may retreat instead of threatening, but speed and venom make complacency dangerous. Maintenance should be planned around escape prevention rather than around direct contact.

☠️ Venom and handling risk

This species should be treated as medically significant. A defensive bite may cause severe local pain and can be followed by wider symptoms such as swelling, cramps, muscle pain, nausea, dizziness, or prolonged discomfort. Human reactions vary, and medical treatment is supportive rather than species-specific.

Do not handle this spider. Use catch cups, clear work areas, locking lids, and slow maintenance. If a bite causes strong, spreading, or persistent symptoms, seek medical advice and explain that the animal is an Old World tarantula.

🌍 Distribution

The World Spider Catalog lists Poecilotheria vittata from India and Sri Lanka. Hobby care sheets often emphasize Sri Lankan material, while taxonomic sources preserve the broader listed distribution. In either case, this is an arboreal species associated with warm forest habitat, tree hollows, bark retreats, crevices, and humid but ventilated microclimates.

For captive care, the useful range cues are:

  • vertical shelter, not open floor space as the main security feature
  • warm stable temperatures without stagnant heat
  • moderate to high humidity with strong ventilation
  • reliable water access
  • minimal disturbance around the main bark retreat

Native range of Poecilotheria vittata

⚖️ Legal status

Poecilotheria vittata is covered by the CITES Appendix II listing for Poecilotheria spp. In the EU wildlife trade system, Poecilotheria tarantulas are treated under Annex B rules. This does not mean private keeping is automatically banned, but it does mean international trade and cross-border movement can require proper permits and proof of legal origin.

The species is not relevant to the Bern Convention because it is not native to Europe. Local laws on import, sale, transport, exhibition, breeding, and dangerous-animal keeping may still apply. Keep invoices, breeder details, import or transfer paperwork, and clear species labels.

🤌 Husbandry

House Poecilotheria vittata alone. Communal keeping is not appropriate for ordinary care and greatly raises the risk of cannibalism, stress, and dangerous maintenance.

Spiderlings can start in small vertical containers with cross-ventilation, a cork sliver or bark tube, and slightly moist but not wet substrate. They grow quickly, so have the next enclosure ready before the spider outgrows its retreat.

Adults need a secure vertical enclosure, commonly around 30 x 30 x 45 cm or larger for a large female. The enclosure should open in a way that lets the keeper block exits and guide the spider without hands entering the retreat area. Magnetic or loose lids are a poor choice for this genus.

The main setup should include:

  • vertical cork bark or a hollow bark tube
  • cover around the retreat entrance
  • a water dish on the floor or a secure elevated dish
  • cross-ventilation
  • enough substrate to buffer humidity but not so much that it stays wet
  • a maintenance plan using a catch cup

💡 Lighting

Specialist lighting is not required. A normal day-night rhythm from room light is enough. If plant or display lighting is used, it should not heat the enclosure or force the spider to remain exposed.

🌡 Heating and temperature

A practical range is about 20-26°C, with the warm end around 23-27°C and a mild night drop to about 19-22°C. Avoid direct heat lamps on small arboreal enclosures. Overheating a tall enclosure can trap hot dry air in the upper retreat, exactly where the spider spends most of its time.

Warm the room or a shelf area rather than the spider directly. Use a thermometer near the retreat height, not only on the floor.

💧 Humidity and water

Aim for roughly 65-75% humidity with excellent airflow. During premolt or very dry weather, a slightly higher local humidity zone is useful, but the enclosure should never become stale or constantly wet.

Provide fresh water at all times. Mist or lightly dampen part of the enclosure only enough to create usable moisture. Mold, condensation that never clears, or a sour substrate smell means the enclosure is too wet or poorly ventilated.

🌿 Enclosure and decoration

Build the enclosure around the bark retreat. A vertical cork tube or slab should let the spider hide completely while still allowing the keeper to see enough of the setup to check water, molts, and feeding response.

Use artificial or live foliage only as cover and web anchors. Avoid heavy decor that can shift during maintenance. Keep the top and door openings simple so an escaped spider cannot vanish behind loose background panels.

🪳 Feeding

Feed appropriately sized roaches, crickets, locusts where legal, or other feeder insects. Spiderlings may feed every few days when growing; juveniles often do well every 7-10 days; adults commonly do well every 14-21 days depending on body condition.

Do not leave prey in with a molting or newly molted spider. Wait until the fangs have hardened: usually a couple of days for small slings and longer for large juveniles or adults. Remove uneaten prey promptly.

🩺 Common problems

The main failures are escapes, overly wet stagnant enclosures, dehydration from dry airflow without water, falls during rehousing, prey left during molt, and bites during careless maintenance.

A sealed retreat and food refusal often mean premolt, not an emergency. Do not tear open the bark retreat unless there is a clear welfare issue. Check water, temperature, and ventilation first. If the spider is weak, curled, injured, or stuck in a molt, reduce disturbance and seek help from an experienced exotics veterinarian or a qualified invertebrate keeper.

📌 Conclusion

Poecilotheria vittata is a striking arboreal display tarantula for keepers who already know how to manage fast Old World species. It rewards a secure vertical enclosure, steady humidity, ventilation, and hands-off routines. It is a poor choice for handling, children, or anyone who is still learning basic tarantula escape management.
