Arizona Blonde Tarantula Care

Species: Aphonopelma chalcodes
Common Names: Arizona Blonde, Desert Blonde Tarantula

The Arizona Blonde Tarantula (Aphonopelma chalcodes) is a calm, hardy, and long-lived New World terrestrial species native to the arid deserts of the southwestern United States, particularly Arizona and parts of New Mexico.

This species is famous for its gentle nature, sandy blonde coloration, and impressive lifespan — females can live over 25 years in captivity. It’s a perfect introduction to New World species and a favorite among beginner and experienced keepers alike.

Quick Facts

  • Scientific Name: Aphonopelma chalcodes
  • Common Names: Arizona Blonde, Desert Blonde
  • Origin: Southwestern USA (Arizona, New Mexico)
  • Adult Size: 12–14 cm (5–5.5 inches) leg span
  • Lifespan: Females 25+ years; Males 8–10 years
  • Temperament: Docile, slow-moving, rarely defensive
  • Experience Level: Beginner to Intermediate

Housing & Enclosure

Aphonopelma chalcodes is a terrestrial burrower that thrives in dry, open setups resembling its natural desert environment.

Recommended enclosure sizes:

  • Juveniles: 20 × 20 × 20 cm
  • Adults: 30 × 30 × 30 cm (12 × 12 × 12 inches)

Setup guidelines:

  • Provide deep substrate (10–15 cm) for burrowing
  • Include a hide, such as a cork bark half-log or burrow starter
  • Ensure excellent ventilation
  • Keep the setup dry, with only a water dish for humidity

A horizontally oriented terrarium is ideal, as this species prefers to stay close to the ground and dig shallow retreats.

Substrate & Decoration

Recommended substrate:

  • Dry topsoil, coco coir, or clay-sand mix (10–15 cm deep)

Add:

  • Flat stones or cork bark for shelter
  • Artificial plants or dry moss for aesthetics (optional)

Keep the setup simple — Aphonopelma chalcodes appreciates stable, arid conditions over elaborate decor.

Temperature & Humidity

  • Temperature: 24–28°C (75–82°F)
  • Humidity: 40–50% (low, dry conditions)

Avoid misting the enclosure. Maintain a small water dish at all times for hydration. These spiders are adapted to arid regions and prefer a dry, well-ventilated environment.

If your home is particularly dry, very light misting once every 1–2 weeks is acceptable — avoid damp substrate.

Feeding & Water

This species is a steady but not overly aggressive feeder.

Feeding schedule:

  • Slings: Every 5 days
  • Juveniles: Every 7–10 days
  • Adults: Every 10–14 days

Feed crickets, roaches, or locusts appropriate to the spider’s size. Remove uneaten prey within 24 hours, as this species can fast for long periods, especially before a molt.

Always ensure a clean water dish is available.

Handling & Temperament

Aphonopelma chalcodes is among the most docile tarantulas in the hobby.

It rarely kicks hairs or shows defensive behavior, making it a popular “display and education” species. However, as with all tarantulas, handling should still be kept minimal — falls can be fatal even from short distances.

Behavioral traits:

  • Slow and deliberate movement
  • Occasional hair flicking when stressed
  • Tends to retreat rather than bite

With care and respect, this species is one of the most rewarding and peaceful companions in the hobby.

Molting

Molting occurs within the spider’s burrow or under its chosen hide.

Pre-molt signs:

  • Refusal of food
  • Lethargy
  • Dull coloration

Do not disturb during this time. Wait 10–14 days after molting before resuming feeding.

Common Health Issues

  • Excess humidity: Can cause respiratory or fungal issues
  • Overfeeding: May lead to lethargy and obesity
  • Falls: Due to heavy body structure, avoid climbing hazards

Otherwise, A. chalcodes is extremely resilient and easy to care for.

Breeding (Overview)

Breeding is slow-paced but rewarding.

  • Pair mature individuals during cooler months (October–February)
  • Introduce the male carefully; females are usually receptive but may be unpredictable
  • The female produces an egg sac with 200–400 spiderlings, which hatch after 6–8 weeks

Spiderlings grow slowly but are hardy and long-lived.

Final Thoughts

The Arizona Blonde Tarantula (Aphonopelma chalcodes) is one of the most iconic New World terrestrials, representing the calm and steady nature of North American species.
