Breeding Notes
Breeding Lasiodora striatipes is possible but not exactly a guaranteed success. Reports are thin, so take it slow, and be ready for the species to surprise you. Conditioning and patience are your best friends, as is a healthy fear of a cranky female on a bad day. Treat everything as cautious guidance, and don’t expect miracles on the first try. If all goes well, you’ll be up to your elbows in spiderlings sooner than you think.
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
For Lasiodora striatipes, the wild breeding season probably lines up with the Brazilian wet season, meaning things tend to get romantic as rainfall increases and food is on the up. Typically, this runs spring into early summer, but the exact months aren’t pinned down.
Wild Environmental Triggers
More frequent rains, a jump in humidity and warm, stable temperatures are likely the big nudges for breeding activity in the wild. Egg laying and mating might coincide with the lushest part of the year, when conditions feel just right and prey is plentiful.
Native Climate Context
This species comes from sultry Brazilian rainforests where there’s plenty of warmth and high humidity, so think 22–26°C with a good splash of rainfall and lush conditions. The changes between dry and wet seasons are modest but enough to spark cycles of activity.
Captive Breeding Window
If you’re hoping for your pair to make magic, aim to pair after a mild cool-down (a couple degrees drop for a month or two), then bump the temps and humidity up to peak rainforest for the introduction. Early spring through early summer in your spider room is a sensible mimic.
Pre-pairing Conditioning
Feed both spiders up well, especially the female, and keep them separate but comfy. Gentle cooling for six weeks can mimic the slight seasonal drop, followed by a slow warm-up and rehydration. Make sure neither is about to moult, as this puts pairings at risk. The female should look robust and freshly moulted if possible.
Male Introduction Guidance
Introduce the male into the female’s enclosure in the evening after dark, when these guys are naturally more active. Watch closely, use barriers or long tongs to separate if it looks dicey, and never leave them unattended—that hungry lady can be unpredictable.
Female Readiness Signs
A female that’s plump, alert at her burrow or hide entrance, and freshly moulted in the past couple of months is about as ready as you’ll get. She may drum or come to investigate rather than dash for cover. If she’s actively defensive and hasn’t moulted in a while, she’s probably not in the mood.
Post-pairing Conditions
Once they’ve met, treat her to warmth and humidity plus a very private, peaceful space so she can lay her sac if successful. Cut food for a bit and avoid major enclosure changes during this stage. Monitor but don’t fuss too much—stress can cause sac eating or abandonment.
Sac Timeline
Reliable timelines are hard to come by for this species, but generally expect anywhere from 4 to 8 weeks from pairing to sac production, and another 6 to 8 weeks for the eggs to develop. Always treat this as a ballpark—each female does her own thing.
Incubation Notes
Leave the sac with mum unless you’ve reason to believe she’ll eat it or conditions are unstable. If pulling it for artificial incubation, keep it humid but not dripping—just a light mist every few days, with good airflow and 24°C as a sweet spot. Open the sac at first sign of darkening spiderlings.
Expected Sling Count
Numbers aren’t well documented, but like others in the genus, you could see anything from a couple of hundred to possibly over a thousand slings from a big, healthy female. Be prepared for an army, not a handful.
Risks and Cautions
Pairings can be tense, and cannibalism isn’t unheard of—never leave them unsupervised. Males should be well-fed and ready to make a quick exit. Watch both for signs of impending moult, as mis-timed pairing can be fatal. Early sacs can be eaten or abandoned if conditions slip or the female feels threatened.
