Trinidad Chevron Tarantula (Psalmopoeus cambridgei) Care Guide

The Trinidad Chevron Tarantula, scientifically known as Psalmopoeus cambridgei, is one of the fastest and most visually striking arboreal tarantulas for sale in the pet trade. Native to the tropical forests of Trinidad, this species is famous for its lightning-fast movements, elegant chevron markings, and impressive webbing behavior. Unlike many beginner tarantulas, the Trinidad Chevron combines speed, agility, and a more defensive temperament, making it a favorite among experienced keepers looking for an active display species.

As juveniles, these tarantulas often show brighter contrast and lighter tones, while adults mature into earthy olive-brown and bronze coloration accented by the signature chevron striping across the abdomen and legs.

Natural Habitat

In the wild, Trinidad Chevron Tarantulas inhabit humid tropical forests where they spend most of their lives above the ground inside tree hollows, bark crevices, and dense vegetation. Their bodies are built for climbing, with long legs and excellent agility that allow them to dart vertically with astonishing speed.

Unlike terrestrial tarantulas that rely on burrows, this species creates silken retreats high off the forest floor. Captive enclosures should mimic these elevated hiding areas to help the spider feel secure.

Trinidad Chevron Tarantula Appearance

The Trinidad Chevron is admired for its sleek, athletic appearance rather than bright coloration alone. Adults typically display:

• Bronze to olive-brown carapace coloration

• Chevron-shaped abdominal markings

• Long slender legs with darker banding

• Dense webbing around retreats and anchor points

While not as vividly colored as some arboreal species, their elegant patterning and active behavior make them highly attractive display tarantulas.

Trinidad Chevron Tarantula Temperament

Psalmopoeus cambridgei is known for being extremely quick and reactive. This species rarely tolerates handling and will usually choose flight over confrontation, but defensive postures and rapid escape attempts are common if disturbed.

Unlike many New World tarantulas for sale in the trade, Psalmopoeus species do not possess urticating hairs. Instead, they rely on speed and defensive behavior for protection.

Because of their agility:

• secure enclosures are essential

• maintenance should be done carefully

• sudden movements should be avoided

This species is best appreciated as a display animal rather than a handling tarantula.

Enclosure Setup

A vertical arboreal enclosure works best for Trinidad Chevron Tarantulas.

Recommended Setup

• Juveniles: 8”–10” tall enclosure

• Adults: 12”x12”x18” vertical enclosure or larger

• Humidity: 70–80%

• Temperature: 74–82°F

• Substrate: 2–4 inches of moisture-retaining substrate

• Ventilation: Moderate to high airflow

Include:

• cork bark tubes

• vertical climbing surfaces

• elevated anchor points

• artificial foliage or leaf cover

This species will heavily web its enclosure and often create elaborate silk tunnels between bark and enclosure walls.

Best Substrate for Psalmopoeus cambridgei

A moisture-retaining substrate helps maintain proper humidity while preventing stagnant conditions.

Ideal substrate materials include:

• coco fiber

• organic topsoil

• sphagnum moss mixtures

• arboreal bioactive blends

Avoid overly wet conditions. Slightly moist substrate with good ventilation works best.

Feeding the Trinidad Chevron Tarantula

This species has an aggressive feeding response and usually accepts prey immediately.

Good feeder choices include:

• crickets

• roaches

• mealworms

• red runner roaches

Feeding Schedule

• Slings: 2–3 times weekly

• Juveniles: Every 4–5 days

• Adults: Once every 7–10 days

Fresh water should always be available in a shallow dish for juveniles and adults.

Growth Rate and Molting

Psalmopoeus cambridgei is considered a fast-growing arboreal species. Slings can reach juvenile size relatively quickly under proper feeding and temperature conditions.

During premolt, expect:

• reduced feeding

• darker coloration

• increased hiding

• thicker web retreats

Never disturb a molting tarantula, especially fast arboreal species that rely on secure webbing during the process.

Is the Trinidad Chevron Tarantula Good for Beginners?

While technically a New World tarantula, this species is usually not recommended as a first tarantula.

Reasons include:

• active behavior

• heavy webbing

• impressive growth

• display potential

Why Keep Psalmopoeus cambridgei?

The Trinidad Chevron Tarantula remains popular because it offers many traits advanced hobbyists enjoy:

• Fast growth

• Constant activity

• Beautiful web structures

• Elegant arboreal posture

• Strong feeding response

• Impressive display enclosure potential

For keepers looking to move beyond slow terrestrial species, Psalmopoeus cambridgei is often one of the first truly dynamic arboreal tarantulas they experience.

Final Thoughts

The Trinidad Chevron Tarantula is a fast-moving and highly rewarding arboreal species that thrives in vertically oriented tropical enclosures. With proper humidity, climbing space, and careful maintenance, Psalmopoeus cambridgei becomes an active centerpiece tarantula that showcases the intelligence, speed, and engineering ability arboreal species are known for.

Whether admired for its webbing behavior, elegant markings, or explosive feeding response, the Trinidad Chevron continues to earn its reputation as one of the most exciting New World arboreal tarantulas available in the hobby.
