Breeding Notes
Pterinochilus murinus DCF Zimbabwe is a fascinating but challenging species to pair, best left to experienced hands. Their breeding is closely tied to seasonal swings in their home environment, but in captivity most success comes from close attention to the spiders themselves rather than the calendar. Be ready for variable timelines, unpredictable sacs, and very quick, defensive spiders throughout. Patience, preparation, and careful observation of each individual's cycles will give you the best chance—but even then, be ready for surprise outcomes.
Wild Breeding Season
Breeding in the wild likely ties in with the regional rains and cooler season changes between late spring and early autumn, but no rigorously confirmed month range is documented for Zimbabwe populations.
Wild Environmental Triggers
Seasonal rainfall events and slight drops in temperature at the onset or end of the rainy period seem to prompt reproductive activity, with spiders often burrowing deeper when the earth is driest and becoming more active with an uptick in humidity.
Native Climate Context
Native to the Zimbabwean savannah, this species deals with hot, dry spells broken up by a marked rainy season. Temperature swings are normal, but it rarely gets truly cold. Humidity jumps up during the rains, but the rest of the year it's back to arid and breezy. Think dusty heat with a splash of rain every so often to get things going.
Captive Breeding Window
Pairings are usually attempted towards the end of the cooler season or just as the warm, rainy season starts—usually late spring to early summer for the southern hemisphere. With UK seasons reversed, that means plan for late autumn through early spring if you're cycling conditions, but most keepers outside Africa go by the spider's moult and maturity cues rather than calendar dates.
Pre-pairing Conditioning
A little extra food for both male and female a few weeks before pairing helps fatten them up and reduces hunger-related aggression. Some breeders lightly increase humidity and shorten daylight for a few weeks to simulate seasonal changes, but this isn't strictly required.
Male Introduction Guidance
This is not a species for casual introductions. Time male visits for when the female is freshly moulted, fed, and actively webbing. Use plenty of barriers—strong forceps, catch cups, and a plan for fast intervention. Introduce the male in the evening and be ready for rapid retreats. Only attempt introductions when both spiders are alert yet calm and avoid any sign of recent moult in the male to maximise his chances.
Female Readiness Signs
A female that's well-fed, actively webbing, and showing interest in the male's vibrations is usually prime. If she's very reclusive inside her burrow and not leaving it at night, she may not be receptive yet. Be wary if she shows extreme aggression—a hungry OBT is murderously defensive.
Post-pairing Conditions
After mating, keep conditions stable: warm, well-ventilated, and not overly wet. Avoid disturbing her except to check she's still eating and webbing. If the pairing took, she'll typically start spinning a dense retreat, sometimes sealing herself in for weeks.
Sac Timeline
Reports vary, but egg sacs might be produced anywhere from 4 to 12 weeks after pairing, depending mostly on temperature, feeding, and the female's condition. There's wide variability with this species—don't panic if it takes longer or seems early.
Incubation Notes
Leave the sac with the female if possible; they're good mums unless stressed. Temps around 24°C and moderate humidity (not wet) seem best. If pulling the sac for artificial incubation, expect spiderlings in roughly 6 to 8 weeks, but watch for early development if it’s particularly warm.
Expected Sling Count
You can expect anywhere from 50 up to 200+ spiderlings in a good sac, though numbers vary with the female's age and condition. Sometimes a sac is dud or much smaller, so be prepared for surprises.
Risks and Cautions
This is not a forgiving species if things go wrong. Females may attack or eat the male, especially if hungry or poorly conditioned. Sac-eating can happen if conditions aren't stable. Both spiders move fast and are defensive—never let your guard down during introductions or sac checks. Not a breeding project for anyone not already comfortable dealing with bolty Old Worlds.
