Breeding Notes
Breeding P. lugardi is a job for the patient, experienced keeper. Clear, species-specific breeding data is scarce, so most advice leans heavily on general Pterinochilus patterns and the species’ natural rhythms—expect a fair bit of trial, error, and luck. Treat this species with respect, provide stable conditions, and brace yourself for surprises. Not one for the faint-hearted or first-time breeder, but a rewarding challenge for those who value patience and resilience.
Breeding information for this species is a bit thin on the ground, so this guidance is based on the best available reports, native climate clues, and sensible keeper caution.
Wild Breeding Season
Precise wild breeding season is unclear, but patterns from the region and related species suggest mating likely follows the rainy season, when food is most plentiful and humidity peaks.
Wild Environmental Triggers
Seasonal rainfall and increased humidity in their arid to semi-arid habitats appear to act as breeding triggers, with spiders more active and visible above ground following rains.
Native Climate Context
These spiders are native to dry, open savannahs in Southern and Eastern Africa. Conditions swing from hot and dry to brief, wetter periods when the rains arrive, so temperature and moisture shifts might be relevant to their breeding cycle.
Captive Breeding Window
Pairings are usually attempted at the end of a cool spell or with a slight rise in humidity, much like after a simulated rain. There's no hard-and-fast rule, but late winter into early spring often works if you're following a UK season rhythm.
Pre-pairing Conditioning
Females benefit from a good feed-up and a slight increase in moisture a week or two prior to introduction, aiming to mimic the seasonal abundance that follows rain. Don’t let the enclosure get soggy—just a little extra dampness in one corner will do.
Male Introduction Guidance
Introduce the male into the female's enclosure at dusk, keeping a close watch—all old world baboons are fast and defensive. A well-fed female in a mature burrow is less likely to see the male as lunch, but always use long tools and give them plenty of space to interact.
Female Readiness Signs
A freshly moulted, robust adult female that’s webbed up a new burrow entrance and is active at night is likely receptive. If she’s aggressively defensive straight away, try again in a few days.
Post-pairing Conditions
After a successful pairing, remove the male promptly. Maintain stable warmth and gently increase humidity for a few weeks, then return to the drier routine as she readies herself for egg-laying. Minimal disturbance is best—she may seal herself off for weeks at a time.
Sac Timeline
Exact timelines for this species are not well documented, but females of related Pterinochilus tend to produce an egg sac around 4–8 weeks after pairing, which may then be guarded or hidden deep in a burrow for a similar period before spiderlings emerge.
Incubation Notes
The female typically incubates the sac in her own burrow. Make sure conditions stay stable, with good ventilation and just a hint more humidity than usual to prevent the sac from desiccating. Don’t attempt to pull the sac too soon; patience is vital.
Expected Sling Count
Clutch size is not firmly documented for this species, but close relatives are known for large sacs—100 to 200 spiderlings wouldn’t be surprising, but expect some variation.
Risks and Cautions
Females can be aggressive toward males and may cannibalise after pairing. They’re fast and defensive, so never let your guard down during introductions. Egg sacs can be abandoned or eaten if the enclosure becomes too wet, too dry, or is disturbed repeatedly. Success rates are inconsistent even among advanced keepers.
