Avicularia braunshauseni

Avicularia braunshauseni hails from the lush rainforests of northern South America, particularly Brazil. These tropical areas are warm, humid, and bursting with greenery—ideal for an arboreal spider that spends its days six legs above ground, hiding among leaves and tree hollows. The climate is predictably sticky, with high humidity and gentle, consistent temperatures day and night. Avics have evolved to thrive above ground in these damp environments, making them quite at home in any leafy, arboreal set-up you can offer. Replicating their jungle origins goes a long way in making them comfortable and ensuring a happy, healthy spider.

Expect Avicularia braunshauseni to reach a leg span of 15–18 cm (6–7 inches) at full maturity, making them one of the larger Avics. Females generally get a bit chunkier than males and live longer, but both sexes are undeniably impressive in size and presence. Their long, elegant legs and plush setae make for fantastic display specimens. Expect them to take a couple of years to reach full size, especially if you’re starting with a little sling.

Avicularia braunshauseni is the definition of arboreal. Instead of scuttling around on the ground, these beauties live their best lives vertically—perched in cork bark tubes, snug in silk retreats or occasionally upside down on the enclosure lid just to keep us guessing. In captivity, you’ll find them webbing up high, often constructing impressive tunnel-like retreats. They’re quite the acrobats, often more at home among the branches than on the floor, so be prepared for some midair manoeuvring when rehousing!

One of the perks of raising Avics: females can be your eight-legged roommate for a solid 10 to 12 years if well cared for (longevity goals, anyone?). Males, on the other hand, lead somewhat tragically short lives, typically reaching only 3 to 4 years before nature calls them to their next adventure. Good husbandry maximises their time with you, so keep them warm, fed, and in fine fettle.

Avicularia braunshauseni grows at a moderate pace—not quite a Ferrari, but not a snail either. With ideal conditions and regular feeding, you’ll often see steady progress from sling to juvenile. Growth can stall a bit if temperatures drop or meals are skipped, but don't expect instant tarantula. You’ll be rewarded for your patience: these spiders mature into absolutely stunning adults.

Avicularia braunshauseni is famously docile, though a little bit skittish and alarmingly athletic when the mood strikes. They’re not aggressive and are far more likely to make a sudden dash or an Olympic leap if startled than stand their ground. While some individuals are calm as cucumbers, others have a knack for dramatic exits. Bites are exceedingly rare if left undisturbed, and their general demeanour makes them a firm favourite—just don’t expect them to sit still for selfies.

Aim for a comfortable 22–26°C (72–79°F) as your primary range. Night-time dips a degree or two lower won’t harm them, but do avoid extremes—no one likes a British winter in the spider room. Use a room heater, heat mat or thermostat-controlled system to keep temperatures stable, but make sure no direct heat source is baking your Avic. Overheating can be more dangerous than slight chill. Do keep an eye on your thermometer, and remember, a well-regulated environment is key to a happy Avic.

Humidity should hover around 70–80%—think dreamy rainforest, not sauna. Achieve this with regular, gentle misting (never soak the enclosure!) and a well-sized water dish for that crucial hydration. That said, Avics need excellent ventilation; stagnant, stuffy air breeds mould and respiratory issues quicker than you can say 'fungus gnat.' Cross-ventilation helps keep things both fresh and humid, so choose your enclosure wisely and don’t be shy with mesh or vent holes.

If you adore a tarantula you can actually see, Avics rarely disappoint. They often sit out in the open or at least have a leg or two dangling cheekily from their webbed retreats. Activity peaks at dusk and night, when you’ll catch them wandering or working on their latest silk project. Juveniles might be shyer, but adults have exhibitionist tendencies and often make excellent display spiders—especially against dark backgrounds where their colours shine.

Avicularia braunshauseni are excellent web artists, producing dense, tube-like retreats high up on cork bark, branches or even the enclosure lid. They’ll web off entrances, hang platters of silk and occasionally make spectacular messes. This habit provides both security and a viewing spectacle. Do expect the enclosure to get a regular silk makeover, especially after moults—it's their version of home improvement.

A varied diet is the key to a happy Avic. Slings happily devour pre-killed or small live prey such as pinhead crickets, fruit flies or curly-wing flies. Juveniles and adults can munch down on appropriately-sized crickets, locusts or the odd roach. Feed slings 2–3 times a week, juveniles once or twice, and adults every 7–10 days. Watch for uneaten prey—Avics can be finicky after moults and don’t appreciate live insects lurking about. Remove anything ignored after 24 hours. Overfeeding leads to rotund spiders and lazy appetites, so keep an eye on their abdomens. Never feed straight after a moult, and always offer water so they don’t snack on your nerves instead.

Go vertical! A tall, well-ventilated enclosure is a must, with more height than floor space. A minimum enclosure size for an adult is around 30cm high, with plenty of cross-ventilation (think mesh panels or drilled vents high and low). Provide an upright cork bark tube or branch for webbing, several anchor points, and some fake or live foliage for that jungle ambience. Substrate only needs to be a shallow layer—just enough to hold humidity, such as coco fibre mixed with sphagnum moss. Add a water dish within easy reach. Don’t drown the enclosure in humidity; mist lightly and keep air moving to avoid mould. A secure, escape-proof lid is essential—Avics are notorious explorers.

A classic 'intermediate' species. Their care isn’t brain surgery, but they do need reliable humidity and top-notch ventilation—a combo that can trip up pure beginners. If you’ve kept a terrestrial species or two and fancy an arboreal challenge, you’re golden. Gentle disposition, forgiving growth rate and magnificent looks make them a rewarding step-up for keepers ready to upgrade from the classic terrestrials.

Avicularia braunshauseni is the perfect blend of manageable care, gorgeous display value and quirky behaviour. They offer hobbyists a taste of the rainforest without the need for a full ecosystem rebuild. Their forgiving temperament and beautiful appearance make them a top choice for those looking to branch out into arboreals. Stay on top of humidity and ventilation, and you’ll be rewarded with a photogenic, visible and endlessly fascinating pet spider. If you’re ready to include a fluffy-legged acrobat in your collection, this Avic is a proper showstopper.
