Avicularia sp. “Shuariana”

Avicularia sp. “Shuariana” hails from the lush rainforests of eastern Ecuador, the traditional homeland of the Shuar people. These arboreal beauties are right at home among the tree canopies of the Amazon Basin, where they encounter a climate that’s both warm and rather on the damp side. Expect high humidity and temperatures that rarely dip beneath 20°C. In nature, they’re found in tree hollows, under bark or snuggled into leaf axils, soaking up the jungle ambience. This native backdrop informs much of how we care for them in captivity. If you’re looking for an exotic ambassador of the Amazon for your spider shelf, you’ve found it!

When fully grown, Avicularia sp. “Shuariana” typically reaches around 11–13 cm leg span—think somewhere between a chunky jam tart and a well-fed biscuit tin spider. Females tend to surpass the males in both size and heft, while mature males are leggier and considerably lighter. Growth rates are steady but not lightning-quick, so don’t expect an overnight transformation from tiny sling to Amazonian heavyweight. You’ll have plenty of time to appreciate their development and that ever-deepening colour.

As a true arboreal species, Avicularia sp. “Shuariana” spends most of its life elevated from the forest floor, building intricate tube webs in tree hollows and among foliage. In the hobby, they’ll gravitate upwards at the first opportunity, often webbing up corners or behind cork bark hides. Expect the classic ‘shoestring webbing’ and the occasional attempt to turn their enclosure lid into a penthouse suite. While rarely seen burrowing, do provide ample vertical climbing space and anchor points for web construction—they’ll make the most of it with endless arboreal acrobatics.

Like many Avicularia, females can live a good 8 to 12 years with the right care—so you’re in for a good spell of companionship if you fancy naming her. Males, alas, draw the short straw, maturing by 3 to 5 years and seldom sticking around much longer after their final moult. Robust feeding, consistent humidity, and stable temperatures all support a healthy lifespan, but these spiders are relatively forgiving if you’re attentive to their needs.

Avicularia sp. “Shuariana” boasts a slow to medium growth rate. Slings will incrementally add size with each moult, but you won’t be seeing rapid leaps every other month. Warmth, regular feeds and optimal humidity all help move things along, but patience is key—these are marathoners, not sprinters. With good husbandry, expect to see distinctive adult colouring emerge in a couple of years.

Avicularia sp. “Shuariana” is generally docile, almost bordering on bashful. If disturbed, they’re more likely to scuttle away or do the famous ‘slow-motion threat pose’ (part intimidation, part interpretive dance) than bite. This species avoids confrontation if possible and, for an arboreal, isn’t overly skittish or quick to bolt. Still, they’re quite speedy when spooked, so caution is always wise during maintenance and rehousing—no one wants a surprise game of “catch the pink-toed parkour champion”! Handle only if absolutely necessary, and even then, think twice.

Aim to keep your enclosure between 21°C and 25°C for best results—think comfortable room temperature, not a sauna. Temperatures can drop to 18°C overnight without much bother, but regular fluctuations below this aren’t recommended long-term. Additional heating like a low-wattage heat mat or ceramic heater may be needed in chilly British winters, but always monitor air temperature with a reliable thermometer and avoid roasting your eight-legged friend by attaching mats to the sides, not the bottom. Too much heat can drive them to stress and dehydration, so steady, gentle warmth wins the day!

Maintain humidity between 70–80%—absolutely tropical, but not monsoon season! Achieve this with regular misting of the enclosure (aim at webbing or décor, not directly at the spider) and a generously sized water dish. What’s critical for Avics is ventilation as much as moisture—stale, stuffy air can lead to health issues. Cross-ventilation (vents high and low) is ideal. Mist lightly every few days and let the enclosure breathe; soggy substrate is more foe than friend. Clean up mould quickly and keep an eye out for any condensation in the enclosure.

Visibility is one of the perks with Avicularia sp. “Shuariana”. You’ll often spot them perched out in the open, particularly in the evening when they get the itch to roam. Juveniles and adults are not especially secretive, making them a fab choice for keepers who enjoy admiring their spiders daily. They’ll occasionally duck into a web tunnel after feeding or moulting, but even then, they rarely vanish for long.

Avicularia sp. “Shuariana” is a committed web architect. Expect to see abundant, characteristic ‘funnel’ or tube webs high up in the enclosure, lining hide entries, cork bark, and corners. Their silken handiwork serves as both a fortress and a hammock, with the spider usually nestled within or just outside surveying the world. Webs are also key for moulting and occasionally as feeding platforms. Be prepared to lose sight of your décor as they claim it for interior design purposes.

Slings thrive on regular meals of appropriately sized fruit flies, micro crickets or pre-killed pinhead roaches. Offer food every 3–5 days while they’re growing; juveniles can handle small crickets or roaches twice a week. Adults are happy with large crickets, locusts, or dubia roaches every 7–10 days. Avics can be fussy eaters if humidity or temperature isn’t right—watch for fasts before moulting or during seasonal changes. Remove uneaten prey after 24 hours to prevent stress and avoid mites. Don’t overfeed—one chunky meal a week for adults is plenty. Growth will be healthy and moults trouble-free with a varied diet and steady routine. Avoid feeding wild-caught insects (they’d rather not risk a tummy ache).

Go vertical: a tall, well-ventilated enclosure is a must. An enclosure measuring 30 x 30 x 45 cm is perfect for adults. Good ventilation is as crucial as humidity—opt for cross-ventilation whenever possible. Use a few centimetres of moisture-retaining substrate (coco fibre does nicely), but focus on adding plenty of upright cork bark, artificial or live plants, and anchor points for webbing. A large water dish helps regulate humidity and keeps your spider hydrated. Make sure all décor is firmly in place; the last thing you want is a cork bark collapse! Avoid overly damp substrate and give your tarantula climbing opportunities—think ‘rainforest retreat’ rather than ‘muddy swamp’.

This species is often recommended for keepers with a bit of experience—think advanced beginner or intermediate. While not overtly demanding, their need for both humidity and plenty of airflow can trip up absolute beginners. If you can keep their air fresh, humidity up, and enclosure escape-proof, you’re well on your way. A great stepping stone for those new to arboreals, with a forgiving attitude that rewards attentive husbandry.

If you’re after a reliably visible, docile, and strikingly patterned arboreal tarantula, Avicularia sp. “Shuariana” ticks all the boxes. Their easy-going temperament, theatrical climbing antics, and signature webbing habits are a constant treat. The gentle humidity and ventilation balancing act keeps things interesting for keepers ready for a challenge beyond your average terrestrial. While not quite a ‘set and forget’ species, their forgiving nature makes it worth your while, and they’ll repay good care with years of acrobatic displays. If you’re ready to join the arboreal club—web hammocks, fuzzy toes, and all—Shuariana makes an excellent addition to your arachnid repertoire.
