Natural Habitat & Behavior

In their native Papua New Guinea rainforests, Selenocosmia arndsti inhabit tropical lowland and mid-elevation regions where they create deep burrows or occupy existing crevices in the forest floor. They are opportunistic burrowers and will extensively modify their enclosure with webbing and substrate manipulation. This species is known for its defensive nature and willingness to stand its ground when threatened. They are voracious feeders with impressive appetites and will readily take down prey items with speed and power.

Care Requirements

• Enclosure: Terrestrial setup with at least 4-5 inches of substrate for burrowing; provide a hide or cork bark
• Temperature: 75-82°F with slight nighttime drop acceptable
• Humidity: 75-85% with good ventilation to prevent mold
• Feeding: Crickets, roaches, or appropriately sized insects once or twice weekly; known for aggressive feeding responses
• Experience Level: Advanced due to defensive nature, speed, and potent venom (Old World species)
