With its robust body, thick legs and predominantly dark appearance, the Phlogius Cape Gloucester makes an attractive addition to specialist tarantula collections. This form is particularly appealing to keepers interested in large Australian tarantulas that display fascinating burrowing, retreat-building and nocturnal hunting behaviours.

Adult females can reach an impressive leg span of approximately 18 cm, making mature specimens especially striking. Whether you’re expanding an established collection or exploring Australia’s diverse tarantula fauna, the Phlogius Cape Gloucester offers plenty of appeal for dedicated arachnid enthusiasts.

Scientific Classification

• Scientific Name: Phlogius sp. “Cape Gloucester”
• Genus: Phlogius
• Family: Theraphosidae
• Type: Australian Tarantula
• Common Name: Phlogius Cape Gloucester
• Distribution: Cape Gloucester region, Queensland, Australia
• Lifestyle: Terrestrial / burrowing
• Adult Female Leg Span: Up to approximately 18 cm

Appearance

The Phlogius Cape Gloucester is characterised by its dark colouration, dense hairing and sturdy body structure.

Key features include:

• Velvety black to dark brown body colouration
• Dense hair covering the abdomen and legs
• Thick, robust legs
• Subtle colour variations across the carapace and body
• Impressive adult proportions
• A distinctive appearance typical of large Australian tarantulas

As the spider matures, subtle colour variations and patterns may become more noticeable. Colouration can vary between individual specimens and may change in appearance following successive moults.

Natural Background

The Phlogius Cape Gloucester is associated with Cape Gloucester in northeastern Queensland, within the broader Whitsunday region of Australia.

Members of the Phlogius genus are terrestrial spiders that commonly use burrows and sheltered retreats for protection and hunting. Their retreats provide a secure environment where they can rest during the day and emerge to capture prey when conditions are suitable.

Providing appropriate substrate, shelter and environmental conditions in captivity allows the spider to establish a retreat and display more natural behaviours.

Behaviour

The Phlogius Cape Gloucester is an interesting species to observe, particularly as it establishes itself within its enclosure.

Like many Australian terrestrial tarantulas, it may spend extended periods inside its retreat, with activity often increasing during the evening and night. It relies on its speed and predatory instincts to capture suitable prey rather than constructing a web designed to catch flying insects.

Behavioural characteristics can include:

• Burrowing and retreat-building behaviour
• Increased activity during darker periods
• Rapid feeding responses
• Spending extended periods sheltered
• Individual differences in temperament and defensiveness

Although some specimens may appear relatively calm, Australian tarantulas can react quickly when disturbed. This species should be treated as a display animal rather than handled.

Phlogius Cape Gloucester Care

The Phlogius Cape Gloucester should be housed in a secure terrestrial enclosure with suitable substrate, shelter, ventilation and access to fresh drinking water.

A suitable setup can include:

• A secure, escape-proof enclosure
• Sufficient substrate depth for burrowing
• Cork bark or another stable hide
• A suitable moisture gradient within the substrate
• Good ventilation
• A shallow water dish
• Appropriate temperature and humidity
• Minimal unnecessary disturbance

The enclosure should provide a balance between moisture retention and ventilation. Avoid waterlogged substrate, while ensuring the spider has access to suitable moisture conditions within its retreat.

As this tarantula can grow to a substantial size, enclosure dimensions should be increased as it matures. A stable retreat and adequate substrate are important for supporting natural behaviour.

Feeding

The Phlogius Cape Gloucester is a carnivorous predator that can be maintained on a diet of appropriately sized live feeder insects.

Suitable food items may include:

• Crickets
• Woodies
• Cockroaches
• Other appropriately sized feeder insects

Prey size and feeding frequency should be adjusted according to the spider’s age, body condition and recent feeding history. Juveniles generally require smaller prey, while mature specimens can accept larger feeders.

Remove uneaten prey when appropriate, particularly if the spider has stopped feeding or appears to be preparing to moult. Fresh drinking water should always be available.

Moulting

Like all tarantulas, the Phlogius Cape Gloucester periodically sheds its exoskeleton as it grows.

During pre-moult, the spider may become less active, refuse food or spend more time inside its retreat. These behaviours are normal parts of the moulting process.

During this vulnerable period, avoid disturbing the spider and do not leave live prey in the enclosure. Allow sufficient time for the new exoskeleton and fangs to harden before resuming feeding.

Maintaining suitable environmental conditions and providing a secure retreat are important aspects of successful tarantula husbandry.

Growth & Adult Size

The Phlogius Cape Gloucester is a large Australian tarantula, with adult females reportedly reaching a leg span of approximately 18 cm.

Growth rate varies depending on sex, age, feeding frequency, temperature and individual genetics. Juveniles gradually develop their adult proportions through successive moults.

Female tarantulas generally have a longer potential lifespan than males, making females particularly appealing to keepers seeking a long-term addition to their collection.
