Avicularia purpurea

Avicularia purpurea, the Ecuadorian Purple Pinktoe, hails from the lush, humid rainforests of Ecuador in South America. These cloud forest regions are rich with dense vegetation, offering plenty of trees and vines for our eight-legged friends to explore. The climate is generally warm and humid, with temperatures hovering between 20–27°C and frequent rainfall creating a muggy atmosphere. In the wild, you'll find A. purpurea tucked away in tree hollows, behind loose bark, or nestled amongst leaves, right where you'd expect a sophisticated spider with an eye for interior décor. Their natural homes teach us a thing or two about creating the perfect arboreal set-up.

Adult Avicularia purpurea generally reach a leg span of 12–14 cm, with females tending toward the larger end and males staying a bit smaller and more leggy. They’re not enormous, but those gangly arboreal legs make them look delightfully spindly—especially when struck by the light, showing off their subtle but stunning purple sheen. Growth is typically steady, and juveniles start out small and pale before donning their adult colours over a few moults. Males mature faster, often reaching adulthood well before females, though they don’t stick around nearly as long.

This species is a textbook arboreal, preferring to spend its days (and nights) off the ground and firmly in the vertical world. In captivity, Avicularia purpurea uses every inch of vertical space you provide, building intricate tube webs amongst cork bark, fake plants, or the nearest corner. They’re quite the little architects, taking advantage of hides and multiple anchor points. This isn’t a fossorial or terrarium-dwelling couch potato; think tree-hugger with a flair for silk decor. Keeping them properly housed up high gives the best views and helps your spider feel right at home.

Females of this species are rather long-lived, with many reaching 10–12 years in captivity if lovingly cared for (and not subjected to handling marathons). Males, on the other hand, live in the fast lane—usually maturing within 2–3 years and living another 1–2 years thereafter. It's one of those stories where the girls outlive the boys by quite a stretch, so plan accordingly if you’re hoping for a long-term spider-mate.

A. purpurea is best described as having a steady, medium growth rate. Slings can take three or more years to reach maturity, particularly the females who seem to subscribe to the 'slow and steady wins the race' mentality. Growth naturally speeds up a touch in males, who want to get out into the world rather sooner. Good feeding, humidity and warmth all help, but don’t expect lightning-fast progress.

A. purpurea is famous for its ‘calm but skittish’ personality. This spider rarely shows aggression—no wild threat displays or foot-stomping drama here! Instead, when startled, it does a vanishing act, darting quickly up and away, occasionally leaving you talking to an empty web while it peeps from on high. They’re generally gentle, but move with surprising speed if bothered. With patience, they’ll often sit in full view, making them a favourite for keepers after good looks without the attitude. Handle them with your eyes only: they’re delicate and easily stressed by handling.

Aim for a daytime temperature range of 21–25°C, keeping things nice and toasty but not like a sauna. Night-time dips to 18–20°C are perfectly fine and mimic natural conditions. While a bit of fluctuation is healthy, avoid letting things get too cold, as these spiders aren’t fans of British winter chills. In most UK homes, a room kept above 20°C will do nicely. Spot-heating with a heat mat on the side of the enclosure is an option if your spider room gets chilly (never underneath!). Always use a reliable thermostat to avoid accidental spider-roastings. Gradual temperature shifts are far less stressful for your pet than any dramatic swings.

Keep humidity at 70–80% RH, although they handle brief dips without drama. Mist lightly around the enclosure two to three times a week—aim for a gentle rainforest vibe rather than a monsoon. Good air flow is crucial; a stuffy, stagnant set-up is more dangerous than a brief spell of dryness. Pair moderate humidity with excellent cross-ventilation to avoid dreaded mould and keep your spider healthy. A shallow water dish is a must, especially for adults—top it up regularly and rescue any drowned crickets before they turn into unpleasant 'soup'.

Visibility is one of this species’ big selling points. They’re often out in the open, lounging lazily on web hammocks or perched against the glass like tiny purple tree dragons. Slings tend to stay tucked away more often, but as they grow, their confidence increases and you’ll catch them out and about much of the time. Night-time is when they shine—literally and figuratively—with feeding, exploring, and delicate web engineering sessions all unfolding under cover of darkness. Most keepers would rate their display value as ‘excellent’ for an arboreal.

‘Webbing artist’ sums them up perfectly. These spiders are tube web legends, spinning dense silken retreats between décor, plants, and cork bark hides. Their webs aren’t messy like some terrestrial tarantulas; instead, expect elegant silk tunnels and suspended platforms that serve as a comfy base. Slings often create entire silk bunkers, while adults refine their lairs into hammock-like structures. Active webbers, they use their silk for safety and comfort, sometimes to catch prey—but mainly as a privacy screen to avoid pesky photographers.

Avicularia purpurea is a brilliant eater, but not a gluttonous one. Slings thrive on pre-killed or pinhead crickets, fruit flies or small roaches two times a week. Juveniles and adults enjoy a varied diet of appropriately sized crickets, dubia roaches, locusts and the occasional waxworm as a treat—offered every 7–10 days. Watch for that classic arboreal hunting behaviour: the spider stalks prey from the web, pouncing in a surprisingly sprightly fashion! Remove uneaten food after 24 hours so it doesn’t bother a moulting spider. Overfeeding can lead to obesity and moulting issues—if your spider’s bum is bigger than its carapace, skip a meal or two. Seasonal fasting is normal (especially when in premoult), so don’t panic if meals are declined. Steady, sensible feeding yields the best, healthiest spiders.

Choose a tall, well-ventilated enclosure (minimum 30cm high for adults) to keep this climber happy. Cross-ventilation is key—think mesh vents on both sides or at the top and base, so their silk palaces don’t turn into fungal jungles. Provide 5–10cm of moisture-retentive yet airy substrate (coco fibre or a mix) to help maintain humidity. Add sturdy cork bark slabs, branches, and plenty of fake foliage or plants to provide anchor points for webbing and climbing. The more options, the busier your spider will be! Place a shallow water dish at the bottom and refill regularly. No heavy clutter needed; keep it tidy for easy maintenance and prime spider viewing. Make sure any openings and lids are secure—nothing scuttles across the living room ceiling faster than a startled Pinktoe.

A. purpurea is a brilliant choice for hobbyists with a bit of experience—think beginner-plus or intermediate. Their needs aren’t difficult, but a little more complex than the rock-solid terrestrials like Brachypelma or Grammostola. Good ventilation, a secure tall enclosure and proper humidity monitoring are the keys to success. For keepers ready to branch out (pun intended) into the arboreal world, this is a wonderful starting point and an endlessly rewarding species.

Avicularia purpurea is a real gem in the arboreal world. The gorgeous velvety purple shimmer, calm (if shy) disposition, excellent display value, and entertaining web-building antics make this tarantula a firm favourite with hobbyists. They aren’t fussy eaters, won’t turn your enclosure into a warzone, and, with proper care, will grace your home for many years. Challenges include their need for good ventilation and humidity balance, as well as occasional moulting quirks. For those looking to progress beyond terrestrials or add a showy, low-drama arboreal to their collection, you can’t do much better. Just remember: admire, don’t handle, and your spood will thrive.
