Feeding Schedule

Spiderlings

• Frequency:
  Feed twice a week.

• Prey:
  Offer small prey such as flightless fruit flies, confused flour beetles, or pre-killed tiny crickets/roach nymphs. Remove any uneaten prey after 24 hours. increase the size of the prey as the spider grows. Prekill any prey that is over 2/3 the size of the sling.

• Post-Molt:
  Wait 24–48 hours after a molt before feeding. Ensure that the tarantula’s fangs are solid black and its exoskeleton is not soft or shiny.

Juveniles

• Frequency:
  Feed every 7–10 days.

• Prey:
  Provide 2–3 small to medium crickets or a medium Dubia roach.

• Feeding Guidelines:

  • If the abdomen is thinner than the widest part of the carapace, feed more prey more often.

  • If the abdomen is wider than the carapace, feed less prey, less often.
    This strategy helps prevent obesity, which can lead to molting complications or increase the risk of an abdomen rupture from even a small fall.

• Post-Molt:
  Wait 3–7 days after a molt before feeding, ensuring that the tarantula’s fangs are solid black and its exoskeleton is fully hardened.

Adults

• Frequency:
  Feed every 2–3 weeks (or as needed).

• Prey:
  Offer 4–5 large crickets or one large Dubia roach.

• Feeding Guidelines:

  • If the abdomen is thinner than the carapace’s widest part, increase feeding frequency.

  • If the abdomen is wider than the carapace, reduce feeding frequency.
    This is crucial to avoid obesity, which can interfere with proper molting or cause dangerous issues such as an abdomen rupture.

• Post-Molt:
  Wait 5–10 days after a molt before feeding, ensuring that the tarantula’s fangs are solid black and its exoskeleton is fully hardened.

Behavior & Temperament

Psalmopoeus pulcher is a fast, skittish species that relies on speed and venom for defense. If startled, it will retreat to its webbed hide but may throw up a threat posture if cornered. While not known for excessive aggression, it can and will bite if provoked.

Like other Psalmopoeus species, P. pulcher is an active hunter and does not hesitate to take down prey. Though reclusive during the day, it often emerges at night to patrol its enclosure.

Due to its speed and venom potency, handling is strongly discouraged.

Breeding Psalmopoeus pulcher in Captivity

Psalmopoeus pulcher, commonly known as the Panama Blonde Tarantula, is an arboreal species native to the tropical rainforests of Panama. Noted for its golden-blonde coloration and relatively calm demeanor, this species is a favorite among tarantula enthusiasts. Breeding P. pulcher in captivity requires attention to specific environmental conditions and an understanding of their reproductive behaviors.

Sexual Maturity & Pairing

• Male Maturity: Males typically reach maturity within 1–2 years, characterized by longer legs and the development of bulbous pedipalps for sperm transfer.

• Female Maturity: Females generally mature around 2–3 years, achieving a robust size indicative of reproductive readiness.

• Pre-Pairing Preparation: We should ensure the female is well-fed before introducing the male to minimize the risk of cannibalism. Providing an enclosure with ample vertical spaces and anchor points for webbing can facilitate a more natural interaction during pairing.

Mating Process

• Introduce the male into the female’s enclosure during the evening or nighttime when tarantulas are more active.

• The male will typically perform courtship behaviors, such as tapping or drumming, to signal his presence.

• If receptive, the female may respond similarly or remain still, allowing the male to approach and attempt copulation.

• After successful mating, some breeders have observed that males can cohabitate with females without immediate aggression. However, monitoring is essential, and separating the male if any signs of aggression appear is advisable.

Egg Sac Production

• If fertilized, the female may produce an egg sac approximately 2–3 months after mating, though some reports indicate longer periods before egg sac production.

• Maintain temperatures around 75–85°F (24–29°C) with humidity levels between 75–85%, ensuring adequate ventilation to prevent mold growth.

• An egg sac can contain a substantial number of eggs, with reports indicating clutches ranging from 28 to over 100 eggs.

Egg Sac Handling (Optional)

• Some breeders choose to remove the egg sac from the female after 15–30 days for artificial incubation.

• If left with the mother, spiderlings (slings) will typically emerge within 6–8 weeks and undergo their first molt to the second instar stage within 3–4 weeks thereafter.

Raising Spiderlings

• P. pulcher spiderlings exhibit a medium-fast growth rate and require stable humidity with proper ventilation.

• Provide enclosures with sufficient vertical space to accommodate their arboreal nature, including structures for climbing and web attachment.

• Feed them appropriately sized prey, such as pinhead crickets or flightless fruit flies, every 3–4 days to support healthy development.

Challenges & Considerations

• Temperament: P. pulcher is generally calmer than other species in the Psalmopoeus genus, making it less prone to defensive behaviors. However, caution is still advised during maintenance to prevent escapes or accidental injury.

• Humidity and Ventilation: Maintaining proper humidity levels is crucial, as spiderlings are particularly susceptible to desiccation. Ensure enclosures are well-ventilated to prevent mold growth.

With their striking golden-blonde appearance and manageable care requirements, Psalmopoeus pulcher has become a popular species among tarantula enthusiasts. Their medium-fast growth rate and relatively high reproductive output make captive breeding essential to maintain healthy populations in the hobby. By focusing on these efforts, we can reduce the need for wild-caught specimens, ensuring the sustainability of this remarkable species for future generations.

Final Thoughts
