Grammostola sp. “Maule”

Grammostola sp. "Maule" hails from the central regions of Chile, with its name paying homage to the Maule province. This area is marked by a Mediterranean climate—think warm summers, mild and often rainy winters, and low humidity for most of the year. The terrain is mostly scrubland, grassy plains, and dry forests, so our eight-legged friend is used to hiding beneath rocks, logs or burrowing into the earth. While not quite sipping Pisco under palm trees, these tarantulas have carved a niche for themselves in an environment with fluctuating temperatures and occasional drought. They’re survivors, making use of whatever cover they can scuttle under. Home might not be glamorous, but it sure is practical.

Your fully grown Grammostola sp. "Maule" should reach a respectable 12–14 cm diagonal leg span—just the right size to impress friends and mildly terrify neighbours. Females tend to be not just larger but chunkier, making males look like they’ve forgotten leg day. Males mature earlier and remain slimmer, while females steadily bulk up over the years. Growth is steady but not outrageous: don’t expect an overnight tarantula behemoth, but you also won’t be squinting at a thimble-sized baby forever. Their size makes them an ideal display tarantula—big enough to see, calm enough to appreciate.

Definitively terrestrial, the Grammostola sp. "Maule" prefers to keep all those lovely legs firmly on (or just under) ground level. In captivity, they’re classic burrowers, often rearranging substrate to craft the perfect hideaway, though they’re generally content with a cork bark hide. Expect your spider to spend much of its time chilling in its den, occasionally creeping out for a midnight snack. It’s a species that appreciates stability—don’t expect acrobatics or tree-climbing antics. If you love a spider that’s dependable, slow-moving, and a master of the "I was here all along" game, this terrestrial gem will tick all the boxes.

For those who want a long-term spider companion, look no further—females of this species can live upwards of 15 years, sometimes even two decades (savings account not included). Males, on the other hand, don’t hang around quite as long. After reaching maturity at around 4–6 years old, males may survive another year or two, giving them just enough time to strut their stuff and hopefully pass on their genes. All in all, if you’re after a pet with commitment issues, this is not the species for you—Grammostolas are here for the long haul.

If there were a tarantula Olympics for growing slowly, Grammostola sp. "Maule" would be a top contender. From sling to adult, you’re looking at a “slow to medium” pace, depending on temperature, feeding frequency, and luck. Regular meals and warm-but-not-hot temperatures will gently encourage growth, but don’t expect a growth spurt every time you turn around. Patience is key! One silver lining: their slow-and-steady approach makes them fantastic subjects for patient hobbyists and a great introduction for younger keepers learning the ropes.

Grammostola sp. "Maule" are the peacekeepers of the tarantula world. They’re calm, deliberate and generally unbothered by gentle disturbance in their enclosure—though they’re not above the occasional sassy hair flick if annoyed. Sudden poking, prodding, or brash movement may startle them into a defensive pose, but this is rare. They’re slow movers, not prone to dramatic dashes or panic sprints, making them a favourite among keepers who enjoy their spiders mild-mannered. Still, each individual is, well, an individual—always approach with respect for their personal bubble.

Aim to keep your Grammostola sp. "Maule" at a cosy 21–24°C—room temperature in most British homes (sorry, no tropical heat lamps needed). They can tolerate dips down to 18°C at night and brief rises up to 26°C, but steer clear of extremes, as sudden hot spells will have your spider digging deeper for relief. If your house turns arctic in winter, a thermostatically controlled heat mat attached to one side of the enclosure (never underneath) will do nicely. Always monitor with a reliable thermometer and, most importantly, avoid cooking your spider—nobody wants a roasted maule.

Keep humidity around 50–65% relative humidity—moist enough to keep water from evaporating instantly, dry enough that mould won’t set up shop. Mist the substrate lightly every week or two, but let the top layer dry out between waterings. A generously sized water dish is a must—no spider should fend off dehydration with a thimble of water. Cross-ventilation is key; good airflow prevents stagnant, stuffy conditions that both tarantulas and keepers despise. If in doubt, err on the drier side—but never let your spider go thirsty. Droplets on the web? Just the right touch.

Not shy, not showy—Grammostola sp. "Maule" is perfectly balanced for those who want a spider they’ll actually see but one that’s never in-your-face. Expect periods of construction work as they rearrange their burrow, followed by hours or even days spent watching the world from their lair’s doorway. Feeding time will often lure them out, and nocturnal forays are not uncommon. If you offer a good hide and suitable substrate, you’ll see just enough of them to stay entertained—excellent for keepers who want visibility without needing a detective’s patience.

Don’t expect a Halloween haunted house—Grammostola sp. "Maule" isn’t much of a decorator. Webbing is sparse and utilitarian: a little around their hide or across the entrance to their burrow, and an occasional matting to help sense passing prey. If you love the look of a webbed-up enclosure, look elsewhere—but if you enjoy subtle hints of silk marking favourite haunts, you’re in for a treat. Their webbing is more about function than flair; it says, "This is my spot. Kindly keep out."

Grammostola sp. "Maule" is the embodiment of moderation when it comes to feeding. Slings can be offered pre-killed pinhead crickets or appropriately sized roaches two to three times per week, removing uneaten food to avoid stress. Juves and subadults do well on a meal once every 7–10 days—adjust to their appetite and growth. Adults can go two weeks or more between meals without complaint, but a plump spider isn’t always a happy one, so don’t be tempted to overfeed. They’re not voracious hunters, but their feeding responses are reliable—wait for the dainty pounce when a cricket passes by! Avoid power-feeding or feeding prey too large (shouldn’t exceed the spider’s abdomen size). Always offer fresh, gut-loaded prey and remove boluses promptly to keep things tidy. When in pre-moult, your spider may refuse food—don’t fret, just wait until it moults and hardens up before offering snacks again.

For slings, a small ventilated tub with at least 5 cm of slightly moist substrate (coco fibre or topsoil) and a bit of moss will do. For juveniles and adults, choose a roomy, escape-proof enclosure, roughly three times the spider’s diagonal leg span for floor space, with more width than height. This is not a climbing species; too much vertical space risks dangerous falls. Provide at least 10–15 cm substrate depth for burrowing (they’ll thank you with some digging). Add a sturdy hide (cork bark, half a flowerpot), a generously sized water dish, and plenty of cross-ventilation—stuffy conditions are nobody’s idea of a good time. Keep décor simple and easy to clean, as this tarantula won’t rearrange your plants but will enjoy moving substrate around. Monitor for mould and keep the enclosure out of direct sunlight and drafts.

Thanks to their easy-going nature and tolerance for minor care slip-ups, Grammostola sp. "Maule" is a solid choice for beginner hobbyists. They’re equally appreciated by more seasoned keepers for their personality and reliability. Their slow growth, docile character, and low maintenance needs make them perfect for anyone dipping a toe into the world of tarantulas—or for the experienced keeper who values a relaxed addition to their collection. Just beware: they might spoil you for more dramatic species!

Grammostola sp. "Maule" is the spider equivalent of that chilled-out mate who’s always up for a quiet night in: undemanding, reliable, and just quirky enough to keep things interesting. With their classic tarantula looks, forgiving nature, and gentle temperament, they’re a top pick for both new and experienced keepers. You’ll get to witness understated beauty, the satisfaction of burrowing antics and, occasionally, the thrill of an epic moult. Challenges? Just the classic slow growth and a tendency to go silent when preparing to moult—but isn’t a slow-burn relationship the most rewarding? They don’t web up a storm, but their presence is all the display you need. They’re beautifully low-maintenance—perfect for hobbyists who want more time admiring and less time fussing. A proper tarantula keeper’s tarantula.
