Trinidad Chevron Tarantula Care
Species: Psalmopoeus cambridgei
Common Name: Trinidad Chevron Tarantula
The Trinidad Chevron Tarantula (Psalmopoeus cambridgei) is one of the most iconic members of the Psalmopoeus genus — large, fast-growing, and visually stunning. Originating from the tropical forests of Trinidad, this semi-arboreal species is known for its impressive size, cryptic camouflage pattern, and calm confidence compared to its relatives.
Although quick and defensive when startled, P. cambridgei is typically less nervous than P. irminia and can be a great next step for keepers looking to expand their arboreal collection.
Quick Facts
- Scientific Name: Psalmopoeus cambridgei
- Common Name: Trinidad Chevron Tarantula

- Adult Size: 15–17 cm (6–7 inches) leg span
- Lifespan: Females 10–12 years; Males 3–4 years
- Temperament: Defensive but confident; less skittish than P. irminia
- Experience Level: Intermediate to advanced
Housing & Enclosure
As a semi-arboreal species, P. cambridgei requires both vertical space and a decent substrate depth. It prefers to live in tree hollows, bark tubes, or web tunnels in the wild, so the setup should reflect this.
Recommended enclosure sizes:
- Juveniles: 20×20×25 cm
- Adults: 30×30×45 cm (12×12×18 inches) or larger
Use a vertical enclosure with excellent cross ventilation and secure doors or lids — this species is strong and quick.
Provide a large cork tube or upright bark slab for retreat-building and a mixture of moss, fake plants, and branches for cover. They will web heavily around their chosen retreat and remain hidden during the day.
Substrate & Decoration
Use a slightly moist substrate layer of 8–10 cm depth made of coco coir, topsoil, and moss. This helps maintain humidity and allows for some burrowing if desired.
Decorate with cork bark, branches, and foliage to provide anchor points for webbing. Unlike many arboreals, P. cambridgei often builds at an angle — between the ground and the vertical hide — creating impressive silk tunnels.
Avoid an overly sterile look; this species thrives in cluttered, naturalistic environments that offer hiding and climbing opportunities.
Temperature & Humidity
- Temperature: 25–28°C (77–82°F)
- Humidity: 70–80%
Maintain humidity with light misting every few days, focusing on one side of the enclosure. Allow the top layers of substrate to dry slightly between mistings to prevent mold.
Ventilation is crucial — high humidity without airflow can cause issues. A small water dish should always be available and kept clean.
Feeding & Water
P. cambridgei has a voracious appetite and is known to take down large prey confidently. Offer a diet of crickets, roaches, locusts, or other suitable feeder insects.
Feeding schedule:
- Slings: Every 4–5 days
- Juveniles: Every 7 days
- Adults: Every 10–12 days
Always remove uneaten prey after 24 hours. These spiders often ambush prey from their webbed retreats — a fascinating behavior to observe.
Handling & Temperament
Although not an ideal “handling” species, P. cambridgei is generally less skittish than other Psalmopoeus species. However, it is still very fast and defensive if provoked.
When working inside the enclosure, move slowly and use catch cups or long tools for safety. If given space and respect, this species will rarely show aggression.
Bites are rare but can be medically significant due to their potency and irritation — always exercise caution.
Molting
Molting usually occurs inside the spider’s web tunnel, where it feels safest. It may close off its retreat for several days or weeks before and after the process.
Signs of a pending molt include:
- Refusal to eat
- Duller coloration
- Sealing of its web entrance
Leave the tarantula completely undisturbed during this time and wait 7–10 days post-molt before feeding again.
Common Health Issues
- Dehydration: Ensure constant access to water and moderate humidity.
- Ventilation Issues: Proper airflow prevents mold and respiratory problems.
- Stress: Avoid bright lighting and excessive enclosure disturbance.
- Injury: This large species can hurt itself if startled — avoid long drops.
Breeding (Overview)
Breeding P. cambridgei is generally straightforward for experienced hobbyists.
- Females are receptive shortly after molting.
- Introduce the male carefully, preferably into her enclosure during nighttime.
- Mating is often calm and successful.
- The female may produce an egg sac containing 100–150 spiderlings after 8–10 weeks.
Spiderlings grow quickly and exhibit typical Psalmopoeus speed and appetite.
