Pterinochilus lugardi

Pterinochilus lugardi, sometimes called the Fort Hall baboon, hails from vast regions of Southern and Eastern Africa, with populations found in Tanzania, Zimbabwe, Botswana and South Africa. These spiders are no city dwellers; they’re adapted to arid to semi-arid savannah and scrubland, inhabiting burrows in sandy or loamy soils where daytime temperatures soar and nights can be surprisingly cool. Their natural habitat is often hot, dry and sparsely vegetated, peppered with rocks and debris that provide both shade and hiding spots. Rain is seasonal, so lugardi are masters at coping with fluctuating conditions—think resilient explorer, not pampered house guest. In captivity, it’s essential to replicate this open, dry environment to keep them thriving.

An adult P. lugardi typically sports a diagonal leg span of 12–15 cm, making it a respectably sized tarantula (and more than enough spider for most shelves). Females tend to be larger, chunkier and longer-lived, whereas males are leggier and more spindly, maturing smaller and more quickly. Full size is usually achieved by the third or fourth year in good conditions. While not the absolute largest of the Old Worlds, they’re certainly not shy about looking dramatic when they stretch out across their webbing. Males, poor things, rarely make it past their first mature season.

P. lugardi is predominantly fossorial, meaning it’s happiest when digging elaborate burrows deep into its substrate. Give it an inch, and it'll take a tunnel! While juveniles might be more opportunistic and occasionally wander above ground, adults specialise in subterranean living, constructing silk-lined retreats where they spend most of their time. Don’t be surprised if your pet vanishes for a fortnight, only to pop up at feeding time looking like the lord of the underworld. These spiders rarely climb, and you’ll seldom find them up a wall, but they will web enthusiastically across burrow entrances and decorate their enclosures with their signature silken tapestries.

Females of this species are the real marathon runners—expect an average of 10-15 years with proper care, so don’t make any hasty commitments! In contrast, males complete most of their life's adventures within 3-4 years, typically passing on not long after their ultimate moult. Compared to some giants in the spider world, this is certainly respectable, but keepers should be prepared for the long haul if raising a female; she’ll likely outlast at least a couple of your favourite TV shows.

P. lugardi is a moderately fast grower, especially for an Old World tarantula. Slings can surprise you with their rapid moult pace if well-fed and kept warm (don’t blink, or you’ll miss the growth spurt). While not as turbocharged as some Asian species, they reliably reach maturity within 2–4 years, depending on food and temperature. Feeding generously as juveniles while maintaining a safe, warm environment will see them thrive and outgrow their starter homes sooner than you’d expect.

This species embodies the phrase “looks can be deceiving.” P. lugardi is usually a ghost—secretive and out of sight—but make no mistake: corner one, and it’ll teleport across the enclosure at slipper-dodging speed. Defensive displays aren’t uncommon if prodded, with classic raised front legs and a bit of fang waving. Quick movements and reclusive behaviour are the norm, so best admire from a distance. Not the sort of tarantula to hang out with at parties, but a fascinating addition for those who value display value and a bit of drama at feeding time.

Aim for a toasty 22–26°C (72–79°F) in your P. lugardi’s home, giving a gentle nod to its equatorial roots. They’re surprisingly forgiving of seasonal fluctuations but avoid letting things dip below 19°C for long. During typical British winters, consider an external stat-controlled heat mat placed on the side or back (not underneath), ensuring the enclosure has a gradient so your spider can choose its own comfort level. Good air circulation is important—stuffy, overheated tanks do more harm than a slightly cool night. Never chase perfection; consistent, moderate warmth is key, and your spider will thank you by staying feisty and active when you’re least expecting it.

Keep humidity around 50–60% RH, letting the substrate in most of the enclosure stay fairly dry, but offering occasional light moistening of one corner—especially for slings and freshly moulted individuals. A shallow water dish is always recommended (even if your lugardi insists on burying it every week). Strong ventilation trumps humidity—stale, humid air is an express ticket to mould. In most UK homes, ambient humidity is fine; you’re not growing orchids. Just be wary during heatwaves or very cold spells, and remember: less is often more with this adaptable spider.

Expect your lugardi to spend much of its time in or around its burrow. They’re not pet rocks, but neither are they zookeepers’ show-offs. You’ll catch them moving at dawn or dusk, or when food is on offer—nothing perks up a lugardi like the pitter-patter of cricket feet. Webbing at the burrow entrance and construction projects are common, offering satisfyingly cryptic evidence of their presence. When out and about, their leggy, sandy appearance makes even brief sightings a treat for any enthusiast.

Lugardi are enthusiastic webbers, especially around their burrow entrances. Their silk serves more as a tripwire system than a decor statement—it provides security and early warning for anything (or anyone) foolish enough to come close. Over time, you’ll see thick carpets of silk adorned with debris, creating a distinctive 'lived-in' look. This behaviour gives hobbyists a peek at natural hunting strategies, with slings sometimes webbing up almost the entire enclosure, whereas adults focus on fortifying the entrance to their tunnel network.

P. lugardi isn’t fussy when it comes to dinner. Crickets, locusts, dubia roaches and the occasional waxworm make for suitable meals. Slings can be fed two to three times per week, taking care to offer prey suitably sized for a quarter of the spider’s leg span. Juveniles and adults appreciate larger meals once a week or so, but don’t be tempted to overfeed; a plump lugardi is a lazy lugardi (and not a healthy one). Their feeding response is impressively quick—expect lightning-fast grabs and the odd threat posture if you interrupt mealtime. Remove uneaten prey after 24 hours to prevent stress or injury, especially after moults. Common rookie mistakes include leaving food in during a moult or offering oversized prey—when in doubt, err on the small side and marvel at how quickly your nimble hunter snatches it up.

Choose a secure, well-ventilated enclosure at least three times the spider’s leg span in length and width, but not excessively tall—fall risks are real, especially for a fossorial species. Substrate (coco fibre, topsoil or a sandy soil mix) should be deep: aim for 15–20 cm to enable proper burrow construction. Provide a starter hide, such as a piece of cork bark partially buried, to encourage initial digging. A shallow water dish should be present at all times, topped up and cleaned regularly—even if your spider seems to think it’s a decorative hat. Avoid overly humid or damp conditions; a dry, airy atmosphere serves best. Secure, fine mesh or perforated lids prevent sudden escapes, and remember: fossorials are adept at lifting loose lids (they don’t skip burrow day at the gym). Decorations like leaf litter or moss are optional but add a touch of naturalistic flair.

Due to their combination of speed, defensiveness and Old World temperament, P. lugardi is best suited for intermediate to experienced keepers. They’re not recommended for novices, mainly because even simple enclosure maintenance can get exciting very quickly. If you have a few New World species under your belt and fancy a fossorial challenge, they make a superb next step for the careful and prepared keeper.

For keepers who appreciate secretive, industrious spiders, P. lugardi offers endless fascination. Its speed, impressive webbing and fantastic burrowing make for a rewarding hands-off experience (the only kind we recommend). While not a beginner’s tarantula, those ready for an Old World challenge will find lugardi delivers both captivating behaviour and the occasional adrenaline boost during enclosure maintenance. Watching your spider emerge from a silk-adorned tunnel to hunt is a true showstopper—and if you enjoy the occasional game of ‘where’s my spider gone now?’, you’ll be in your element. An excellent, low-maintenance pet for those who respect boundaries and appreciate the wild at heart.
