Ybyrapora sooretama

Ybyrapora sooretama hails from the lush rainforests of eastern Brazil, specifically within the Atlantic Forest region. This area is known for its warmth, high humidity, and dense foliage—a far cry from the drizzle of the British Isles! The habitat comprises rich biodiversity, with their homes usually found in the branches and crevices of living trees. The climate offers a pretty consistent temperature year-round, favouring the sort of conditions that make t-shirts and shorts standard attire in the forest. Expect balmy days, gentle breezes, and, of course, plenty of rain—it's the perfect setup for these dainty arboreal spiders to thrive.

As adults, Ybyrapora sooretama reach a modest 8–10 cm diagonal leg span, making them one of the more petite arboreal species. Females are generally chunkier and live longer, while males mature faster but end up slightly leggier. They don’t grow into the giants you might find in some other genera, but their delicate size adds to their charm and accessibility. This manageable stature is good news for keepers with limited space—or those who just love the idea of a little arboreal ninja.

Ybyrapora sooretama is the very embodiment of 'tree-dweller'. These tarantulas spend their time well above the ground, making the most of vertical space with classic arboreal hustle. In captivity, they construct messy but charming web tunnels in the upper corners of their enclosures and often select vantage points to survey their leafy domain. They’re known for their agility and are rarely seen poking around the substrate unless they’ve dropped a cricket and fancy a chase. Give them height and they’ll reward you with acrobatics—think Cirque du Soleil, but with more legs.

Females can live a charming 10–12 years if well cared for, taking their time to enjoy every day in their tree-top mansion. Males, living life at a brisker pace, tend to mature within 3–4 years and, alas, only expect another 1–2 years post-maturity. That’s the usual trade-off in Tarantula Land: the girls get more birthdays, the boys get a turbo boost. With a gentle approach, healthy feeding, and good conditions, you’ll find your female companion sticking around for the long haul.

Ybyrapora sooretama are best described as having a medium pace of life—not too quick, not painfully slow. They’ll go from sling to sub-adult in a few years, especially if you offer regular meals and keep their temperature nice and comfy. Like any tarantula, their molting rate will vary depending on feeding, temperature, and stress. If you’re patient, you’ll be rewarded with a well-sized adult in about 3 years for females, a little sooner for males eagerly seeking out romance.

Ybyrapora sooretama is famously laid-back by arboreal standards. They’re much less skittish than their Caribena or Psalmopoeus cousins, preferring calm contemplation over wild dashes. Bites are virtually unheard of and they rarely show a threat posture. That said, their first instinct with disturbance is to scuttle into a silken retreat. They can move quickly if startled, so always be cautious when opening the enclosure—they’re more 'quick ninja vanish' than 'stand and fight'. Calm, patient keepers will enjoy their steady personalities.

You’ll want to keep Ybyrapora sooretama at a pleasant 22–26°C. If your house is generally room temperature, you might not need extra heating; just avoid letting them get chilly—anything below 20°C and they’ll be considering a move to Spain! Consistent warmth is key, but avoid direct heat mats or lamps in arboreal enclosures as they can dry things out and lead to crispy spiders (not ideal). If you do need to heat, a space heater for the spider room is far safer. Always monitor with a reliable thermometer for peace of mind.

Humidity for this species sits happily at 70–80% Relative Humidity. This isn’t an excuse for swamp-like conditions, though! Use a water dish (yes, even baby arboreals need it), and mist one side of the enclosure lightly once or twice a week. The other side stays dry, to give your spider options. Excellent ventilation is non-negotiable—stuffy air invites mould and crabby spiders. Aim for cross-ventilation in your enclosure and you’ll keep air fresh and humidity just right.

Ybyrapora sooretama are fantastic display spiders, especially for an arboreal. They tend to hang out in plain view, often perching at the mouth of their web tunnel or even out on a leaf for all to admire. They're far less ‘disappearing act’ than some old world tarantulas, especially in the evenings when they're more active. Give them climbing structures near the front or sides of the enclosure, and you’ll likely spot their dainty forms showing off their subtle greens and browns rather frequently.

Webbing is a lifestyle for these energetic silk-spinners. Expect to see a tidy network of tunnels, hammocks, and curtains draped all over the vertical spaces you provide. They love constructing retreats high up, so include cork bark tubes and foliage for maximum creativity. Their webbing isn’t as thick or exaggerated as Caribena, but it’s functional and lovely. Watching a sling slowly entomb a fake leaf is a treat and lets you appreciate how adaptable arboreal tarantulas can be.

Ybyrapora sooretama are enthusiastic but not greedy eaters. Slings will thrive on fruit flies or pinhead crickets every 3–5 days. Juveniles can take on appropriately sized crickets, mealworm segments, or dubia roach nymphs about twice a week. Adults enjoy a moderate meal—one or two adult crickets (or the equivalent) every 7–10 days. Avoid overfeeding, as it can lead to sluggishness and an unsightly abdomen (the 'couch potato' look doesn’t suit anyone). Remove uneaten prey within 24 hours to prevent stress. Offer prey near their web entrance and watch as they pounce with precision. As with all arboreals, feeding on vertical surfaces is their preference, so no 'dinner on the floor', please.

A vertically oriented enclosure is a must—think tall, not sprawling. Both acrylic and glass work well, as long as there’s robust cross-ventilation. For juveniles and adults, heights of 20–30 cm and widths of 15–20 cm are ideal. Plenty of anchor points for webbing: cork bark tubes, fake leaves, and twigs are all fair game. Substrate can be shallow (2–5 cm of coco fibre), as they rarely venture down, but do include a small water dish at the bottom. Hides aren’t needed if you provide vertical retreats. Misting one side and providing airflow helps keep conditions just right. Always secure the lid; these lot have a degree in escapology.

This is a splendid species for keepers with a bit of experience under their belt—think advanced beginner or intermediate. Their gentle disposition and medium growth make them less daunting than some arboreal speedsters. If you’ve looked after a terrestrial or two, Ybyrapora sooretama is a logical (and rewarding) next step into the treetops. Just remember: as with any arboreal, escape prevention and careful rehousing are key, so confidence with fast spiders is a plus.

Ybyrapora sooretama tick a lot of boxes for modern hobbyists: beautiful subtle colours, manageable size, charming arboreal behaviour and webbing, and a temperament that won’t give you palpitations. They’re ideal for those looking to dip a toe into the arboreal world or for experienced keepers who appreciate display spiders with personality. The main challenge is staying on top of humidity and planning for their ninja moments, but the reward is a captivating, gentle tree-dweller that’s a pleasure to keep. They don’t often feature in the spotlight, but those in the know wouldn’t be without one in a collection.
