Hapalopus sp. 'Colombia' — undescribed
Hapalopus sp. 'Colombia' — the Pumpkin Patch Tarantula — is native to the Pacific coastal lowlands of Colombia, occupying humid tropical forest edges, grassy plains, and areas rich in leaf litter. The region is warm year-round with consistent seasonal rainfall that keeps ambient humidity elevated.
As a terrestrial burrower, the Pumpkin Patch constructs silk-lined tunnels extending several inches below the surface, providing shelter from predators, a moulting refuge, and a stable microclimate. It is also a prolific surface webber, extending elaborate silk tunnel structures across the enclosure and anchoring to any available decor — one of its most entertaining captive traits.
Taxonomy note: Hapalopus sp. 'Colombia' has not been formally described to science. Two hobby forms exist — the "large" (3.5–4 in DLS) and the "small" (up to 2.5 in) — which may represent geographic variants or distinct species. Keep the two forms separate to avoid mixing lineages.
Prioritise floor space and substrate depth over height. Security is critical — this species is small and extremely fast, and gaps in the lid or sides will result in an escape.
| Life Stage | Recommended Enclosure | Substrate Depth |
|---|---|---|
| Spiderling (under 0.5") | Deli cup or small vented container | 2–3 cm, enough to burrow |
| Juvenile (0.5–1.5") | 8–16 oz enclosure | 3–4 cm |
| Sub-adult / Adult | Small enclosure, 20×20 cm footprint | 4–6 cm |
Cross-ventilation (side vents plus screened top) helps maintain airflow without over-drying the substrate. Provide a cork bark hide and a water dish sized appropriately — a bottle cap works for spiderlings.
| Parameter | Target |
|---|---|
| Temperature | 75–82°F (24–28°C) |
| Ambient Humidity | 60–70% RH |
| Substrate | Slightly moist at depth, drying toward surface |
| Water dish | Always available; refresh every 2–3 days |
Lightly mist one corner of the enclosure every 1–2 days to maintain a moisture gradient. The Pumpkin Patch tolerates a reasonable humidity range and adapts well to most household conditions.
Pumpkin Patch Tarantulas are active, responsive feeders with a strong prey drive. They will actively hunt prey rather than simply waiting in ambush.
Prey: Appropriately sized crickets, Dubia roaches, mealworms. For spiderlings, pre-killed or freshly killed micro-prey (fruit flies, small crickets) works well.
Frequency: Spiderlings every 3–5 days. Juveniles every 5–7 days. Adults every 7–14 days. This species has a fast growth rate and benefits from regular, consistent feeding in early life stages.
Remove uneaten prey within 24 hours. Check beneath webbing — this species frequently covers prey with silk.
The Pumpkin Patch grows quickly — spiderlings can reach juvenile size within their first year with consistent feeding. Moult frequency slows considerably as the spider approaches adult size.
Pre-moult signs: Darkening abdomen, food refusal (sometimes for weeks), increased webbing activity, possible enclosure entrance being sealed with silk.
Post-moult: Fast for 10–14 days minimum after moulting. The new exoskeleton is soft and the fangs are non-functional until fully hardened. Each fresh moult reveals the most saturated version of the species' vivid orange-and-black colouration.
