New species of Decoy Spider likely discovered at Tambopata Research Center
From afar, it appears to be a medium-sized spider about an inch across, possibly dead and dried out, hanging in the center of the spider web along the side of the trail. Nothing too out of the ordinary for Amazon. As you approach, the spider starts to wobble quickly forward and back, letting you know this spider is, in fact, alive.
I’ll tell you all about this amazing spider below. If you’d like to discover — literally — even more jungle species, join in our Discover New Species project!

The ‘decoys’ were built with a variety of forms and numbers of legs.
Step in even closer and things start to get weird- that spider form you were looking at is actually made up of tiny bits of leaf, debris, and dead insects. The confusion sets in. How can something be constructed to look like a spider, how is it moving, and what kind of creature made this!?
It turns out the master designer behind this somewhat creepy form is in fact a tiny spider, only about 5mm in body length, that is hiding behind or above that false, bigger spider made up of debris. After discussing with several spider experts, we’ve determined it is quite probable that this spider is a never-before-seen species in the genus Cyclosa.
This genus is known for having spiders that put debris in their webs to either attract prey or, as in this case, confuse anything trying to eat them.
Update: See the discovery of this spider on video!
Decoy Spider
You could call it a Decoy Spider, in a sense. The spiders arrange debris along specialized silk strands called stabilimenta in a symmetrical form that makes it look almost exactly like a larger spider hanging on the web. Studies have found that some Cyclosa species have a higher survival rate against potential predators like paper wasps because the wasps end up attacking the debris on the web rather than the spider itself. As seen here, Cyclosa can make debris look a bit like a spider, but not nearly as detailed as the spiders found at the Tambopata Research Center which have a complex form that actually looks like a bigger version of themselves, complete with legs and all.
After asking other experts, I cannot seem to find another example of an animal creating a bigger, decoy version of itself to escape predation, making this species not only interesting to taxonomists naming new species but to those who study animal behavior, as well.
After 3 days of searching, we found about 25 of the spiders found in one floodplain area surrounding this Amazon jungle lodge, the Tambopata Research Center. Extensive searches in other areas did not turn up any of the spiders, showing that they have a rather restricted range, at least locally.
What’s the next step after discovering a new species?
It takes a lot of time and effort to go from finding it in the field to actually describing it. Specimens will have to be collected to compare to known species, dissections will be done on identifying features like the genitalia, and descriptions will have to be written to show why this species is different from others, a type specimen will have to be selected, and the eventual publication of all of that information in a journal. Only then can it be considered a named new species to science.
For now, enjoy pointing it out with other explorers from around the world who come to Tambopata to check out all of our strange, interesting wildlife.

We stayed last february for 4 nights in the TRC lodge. I never could have imagined that I would explore the amazon in such confortable and immersive way. The lodge itself is such a luxurious place, in the middle of nowhere! The food was nicely curated everyday to offer new bits and pieces of the Peruvian cuisine. The absolute highlight of our stay here was for sure the activities and our guide Carmen, who accompanied us everyday! We were able to choose our everydays activities with our very reduced group and our guide. Carmen guided us on very activity, spotting and explaining what animals we saw and interesting facts about our surroundings. Her knowledge and excitement were so infectious that it would even make the sightings even more special! Read all
One of the most unique experiences we’ve had! You are deep in the heart of the Amazon and truly feel immersed in nature. Our guide Dino was awesome and taught us so much about the rainforest-he is like a walking encyclopedia, and his love for the forest really shows. Also very unique to listen to nightly talks from the research team-it really adds to the experience. Food was great and staff very friendly. Bring lots of bug spray and an adventurous spirit!

The lodge was fantastic; they were very attentive to our needs. The dining staff brought special bread for my wife because of her celiac disease and offered to prepare dishes specifically for her to meet her dietary needs. The lodge guides were truly knowledgeable and went out of their way to help us see all the local wildlife. I especially loved the mosquito net service they provided. I was worried we’d be eaten alive, but their setup is fabulous; I had no concerns once I saw how they installed the impenetrable nets and curtains. The meals were as good as—or better than—anywhere else we ate in Peru. We saw the following animals: macaws, parrots, parakeets, pale-winged trumpeters, tamarins, caimans, capybaras, and a ton of insects on our night hike. Read all
We had an excellent guide who was very knowledgeable about the local animals, birds, and plants. I learned a lot. We also participated in the Wired Amazon experience and just received the video clips of the animals that walked by - ocelots, agoutis, ... some amazing animals. It was fun to set up the camera traps, and now I'm inspired to get one for our backyard. Read all
Refugio Amazonas was one of the most memorable and immersive experiences of our entire trip to Peru. From the moment we arrived, it felt like we had entered a completely different world. Waking up to the sounds of the rainforest, exploring the Amazon with knowledgeable guides, spotting wildlife, and disconnecting from everyday life created an experience we will never forget. The guides and staff were exceptional throughout our stay. Everyone was warm, welcoming, knowledgeable, and clearly passionate about the rainforest and the guest experience. Their enthusiasm and expertise added so much to every excursion and activity. For this type of Amazon adventure, Refugio Amazonas felt top-tier. The wildlife experiences were remarkable, the setting was beautiful, and the overall level of immersion was exactly what we were hoping for when we added the Amazon to our Peru itinerary. Read all
Wow what an experience! If you want to be fully immersed in Amazon life in a wonderful , comfortable eco lodge, and not have expectations of a 5 star city hotel (I'm not sure why you would, but some reviewers seemed disappointed it wasn't!) you will love this. You will be in a group, 6 in ours, but you don't all have to do the same activities, you just join another group. Plenty of spaces to chill and downtime if you need it...its hot and humid! There's a fan in the room and I heard the superior rooms have a fan under the mozzie net. Take a torch! We were never bitten, used deet repellent only. They provide rubber boots if you want them, some of the trails were very muddy, but we managed in our walking boots. We loved the open wall to the jungle, despite some bugs, but not too many surprisingly. Sooooo much wildlife, all sorts of monkeys, otters, turtles, caiman, different birds, capybara etc. Luis M was our guide, a local, and he could spot a spider from 5 metres I'm sure... great sense of humour and a wealth of knowledge, loved him. We spent 3 nights 20th-24th April, it rained on a couple of occasions but not much. Perfect holiday for an immersive wildlife experience! Read all
Beautiful lodge in the rainforest, very well maintained and clean. We had a lot of fun and excellent guides. The rooms and facilities were top-notch! Read all
We stayed at Posada Amazonas Lodge in May 2026, and it was a truly unique experience. It’s important to note that the concept is unlike a traditional hotel: the rooms (the lodge has around 30 in total) are built entirely of wood and open completely to the rainforest, with no windows. The walls are about two meters high, and everything is open-air, meaning you can hear your neighbors as well as the sounds of the forest throughout the night. There is a hot-water shower with drainage flowing through wooden beams beneath the floor, and the beds are protected with mosquito nets. The food is delicious and nutritious, and one pleasant surprise was the excellent Wi-Fi connection (Starlink) available both at the lodge and on the boats. The logistics are flawless from the moment you land in Puerto Maldonado, including a short car ride (accompanied by a security company) followed by a forty-minute cruise along the Tambopata River. The staff is incredibly friendly. Our guide, Luis M. (a member of the local community that manages the lodge), was simply outstanding, with eagle-eyed vision for spotting wildlife and always wearing a smile. Tour highlights: Canopy Tower: a 42-meter tower rising above the treetops with panoramic views. We loved seeing the river, the rainforest, and even the distant Andes Mountains on the horizon. We returned at night during a nocturnal wildlife tour, where we spotted tarantulas, white sloths, and tree frogs. Lake Tres Chimbadas: a peaceful catamaran ride (without a motor) where Luis showed us a group of red-bellied monkeys, giant otters, and caimans. The scenery and tranquility are incredible. Trek to the “Great Tree”: a forest hike where we saw deer, jaguar tracks, a three-toed sloth, and more wildlife. At the end of the trail, we reached the gigantic ceiba tree: around 500 years old, approximately 60 meters tall, and with an impressive 11-meter base diameter. Highly recommended for anyone wanting to experience the true Amazon! Read all
An exceptional experience that truly exceeded all expectations. What impressed me the most is that here they genuinely want to make your stay as comfortable as possible — and that, to me, is what real high-level service is all about. The guide really tries to fill every excursion with emotions and memorable moments, turning simple activities into meaningful experiences. The kitchen team puts great effort into variety and introduces you to Peruvian cuisine — it feels like a small гастрономic journey. Housekeeping works like invisible bees — you don’t notice them, but everything is always perfectly taken care of. Another big highlight is the comfort level: stable electricity and surprisingly good internet both on the way and at the lodge, powered by Starlink. Having this level of connectivity in the middle of the jungle is something truly special. From reception and the bar to the boat driver — everyone is genuinely warm and happy to have you. You can really feel that each person is a small but important part of one big system delivering outstanding eco-tourism service. Bravo — achieving this level of service in the wild is not easy, and it shows. This experience was very valuable for me and my family. I won’t get tired of thanking you for the emotions you gave us. Highly recommended. Dear travelers — don’t hesitate. Go, enjoy the incredible nature and the level of service. This is something you will remember for a lifetime. Read all
We had the most amazing time at Refugio Amazonas for 3 nights, with a huge thanks to our guide Juan Carlos! On the first afternoon we sat down and planned our activities, which we loved! We came face to face with hundreds of birds, tarantulas, leaf carrying ants spanning 10 meter motorways to work and deliver the leaves to the ant house for food, parasites, and even leaves that cause natural dyes on oxidation - we learned so much. Carlos was genuinly interested in showing us everything the jungle had to offer, humorous and caring too. Carlos knew anything and everything about what was around us, pointing out things and creatures that the untrained eye would miss, carrying a telescope at all times for us to see the birds, ensuring we got magical videos on our phones using the telescope!

Many thanks to Refugio Amazonas for an unforgettable experience! Brenda and team were so wonderful and accommodating, and Alan was a great guide. Thank you for a memorable experience! :) Read all
We had an excellent time at Tambopata research center. We are tourists like most who now visit the center, but it’s great to know that you can support research and the local community by visiting a place like this. Our guide for our trip, Esau, was extremely knowledgeable and showed great passion for his job. He described it as a hobby and he would get very excited if you spotted a specific bird or a tree. His specific knowledge about each and every creature in the forest was very impressive and I would recommend asking for Esau to be your guide in the future if you plan to visit. The hotel itself is unique. You are in the middle of the Amazon rainforest - the accessibility to nature is second to none. There are no windows in the hotel rooms. We had bugs in our room, of course, but the mosquito nets keep everything out and, actually, we both slept very well. The bar staff, Harrison, is very knowledgeable with drinks and works very hard. The food isn’t the best you’re ever going to have, but you have to remind yourself you are in the middle of the rainforest and that it takes a 6 hour round trip to get to the nearest town, and so the job that the hotel does in respect of the food is actually intuitive and very good. I would recommend this hotel to my peers and I would love to visit again in a few years time. Read all
