THE LITLLE WORLD OF the Ant and the Treehopper

Stories

Discovering Insane Mutualism between Ants and Treehoppers (Membracidae)

When you think of the Amazon Rainforest – what do you think of? Usually, the rainforest comes to us in images of color, biodiversity, and an exoticness that echoes in our imaginations.  We often think of fauna or birds – colorful macaws and mysterious jaguars. 

But when one steps off the boat or plane, one might be surprised to find that the Amazonian ambassador is not the regal jaguar, but rather the treehopper. The little creepy crawlies that dress to impress and though they may be little, a finer representative of biodiversity is not to be found.

To many, the treehoppers’ entire appeal rests on their pronotal ornament (a plate-like modified structure covering the dorsal surface of the thorax). These appendages are bizarre, and their function is still being debated amongst biologists. However, what is known, is that some species use it as a form of physical protection (cage-like pronotum), others as a form of mimicry (ant/wasp-like), and still others as camouflage (thorns, spines, trichomes-like).

To stop and watch the rich lives of the treehoppers unfold is one of the many pleasures the rainforest has to offer and the more one looks, the greater the complexity of this small world – they engage in animal husbandry (ant farms), economies of scale (treehoppers and they’re young form large groups catered to by ants), commodity market dynamics (exchange of nutrients for protection) – in a word, mutualism.

While some species of treehopper remain solitary, many have formed a special relationship with a bodyguard that serves and protects their interests and is paid in a kind of gold – honeydew. Understanding where this gold-honeydew comes from and its importance is key to understanding the mutualism that has evolved.

 An ant gently palpates and crawls over a treehopper providing the stimulus for physical feedback which stimulates the release of honeydew. 

The story begins at the bottom of the food chain, where we find the real workhorses of any ecosystem: the plants. The lifeblood of the plant – sap – holds all the nutrients and sugars necessary for survival and growth. It represents a bounty for those daring and evolutionarily ambitious enough to take advantage of it. But this is no easy task because the leaves and stems are often armed with mechanical (spines or trichomes) as well as chemical defenses (tannins, agglutinating proteins, etc. …). So, like the safe-cracker, the treehopper uses specialized tools for the job. (Mutualism between Ants and Treehoppers)

 

It probes the surface of the plant before using its needle-like modified mouth, the proboscis, to break in and steal sugars. However, the sap is under pressure, and thus puncturing the phloem (which is responsible for nutrient transport) results in an uncontrolled, high-pressure stream.  In order to deal with this, the insects must discharge huge volumes of the sap so that they don’t explode. Thus, they filter out the nutrients they need and extrude the rest in the form of a sugary exudate – honeydew, which can either be flicked off or else consumed more directly by attendant insects. And no organism is better poised to take advantage of this supply than the super-organism, the ant.

Mutualism between Ants and Treehoppers…

Over time, a mutually beneficial relationship has evolved, whereby ants, possessing defensive bites and stings, protect the treehoppers which have taken on the biological equivalent of living spigots. The ants will palpate them, move them from one place to another to maximize their productivity, protect them from parasitization and predators, and all to ensure a continuous supply of their precious resource – honeydew. 

So, next time you’re in the Amazon, stop a moment, lean in, and smell the flowers. And you just might see that it’s not the jungle rose where sweetest lies, but rather the inconspicuous treehopper, the thorn that’s not a thorn, whose sweetness lies.

A truly magical experience. It’s set in a completely unique location in the middle of the jungle with no other lodges around. The guide we had (Jarinson) was the best, so so knowledgeable, experienced and lovely to spend the time with. The lodge itself is beautiful and food was great too. Would highly recommend. Read all

Interesting bus and river boat rides bring you to Posada Amazonas on the Tambopata River. It’s managed by the Ese Eja indigenous community. Luis M., our guide, helped us observe birds and learn about plants and other animals. A canopy tower, clay lick and oxbow lake are highlights. All personnel are extremely kind and researchers give short lectures in the evening. The food is delicious! Excellent mosquito netting in rooms! Read all

Wow where do I even begin. This was one of the most unique and special experiences we've ever had. You are smack dab in the middle of nowhere, deep in the Amazon jungle. Surrounded by plants and animals of all kinds and some of the most breathtaking scenery you can imagine. And in the company of scientists doing conservation work all around you. The facility is gorgeous beyond belief. Everything is so thoughtfully prepared, from water servers everywhere to comfy couches to hammocks to raised walkways so you can pad around barefoot without feeling like you're going to step on a scorpion. The meals are positively gourmet. They have delicious fresh juice out for you when you come back from your hikes. We spend 2 days there and I genuinely feel like I saw the jungle. 2-3 excursions a day with a private guide to show you everything from plants to birds to animals to a very tall tower where you can watch the sunset over the canopy. We only had 3 people in our group but I believe there can be up to 7. You have the same guide your whole trip so you really get to know them. Johan was our guide and he was wonderful. And I do believe the number of excursions/type/length can be adjusted based on your groups physical ability. The rooms are beautiful and comfy and they help you prepare mosquito netting at night so you can be comfortable. There's a full bar, in the middle of the rainforest. At night there are short (30 min) lectures you can go to if you want where the scientists talk about their work. Fascinating. We loved that the center was very eco conscious and put a lot of effort into being low impact while also offering a truly luxurious experience. That being said. Do yourself a favor and read the web site. This experience will not be for everyone. Ppl posting negative comments here about the heat, bugs, open rooms, etc did not do their homework. You are far, far inside pristine Amazon jungle. It is hot, humid, rainy, and there are bugs. You can expect to use your lovely shower a few times a day to cool off. Fortunately you have lots of down time during the heat of the day to rest under the ceiling fan in your room. There were lots of grasshoppers, moths etc around our room but honestly we didn't have many issues with biting insects or mosquitos despite visiting during the rainy season (we did use bug spray). Your room has one open wall that faces nature. Yes, technically than means someone could see you walking around naked in your room, but you are 15 feet up in the air and facing directly into thick jungle, there is no one out there besides birds and monkeys to see you. They do cut the brush back so nothing except maybe some birds could get into your room. The sounds are magical at night and during the day. It's hot especially if you go during the rainy season as we did. If you hate bugs or can't handle life without air conditioning, this is not for you. Truthfully we had no issues sleeping. Ventilation is another big benefit of the one open wall. Think of this as the glampiest glamping you'll ever do and you will not be disappointed. Read the web site and reviews thoroughly and you won't be surprised. Being good hiking shoes, a lightweight waterproof jacket, refillable water bottle, a hat, binoculars (you can rent them too), bug spray, and sunscreen. Lightweight long sleeved shirts and long pants are essential bc you want to be covered so you won't get bitten or in case you brush up against a nasty plant. We saw monkeys, macaws, capybaras, owls, a caiman, and some cool jungle bugs. The guides even have a telescope you can use to both look at the animals and take great pictures with your phone. once in a lifetime experience in one of the most special and precious ecosystems in the world. Worth every penny and honestly we felt the price was cheap considering what you get. The highlight of our trip to Peru. Thank you so much. Read all

It was our first time in the rainforest and we wouldn't do it any other way. The boat rides on the Madre de Dios and the walks through the rainforests were both exciting and peaceful. Exciting when we spotted wildlife and peaceful as we settled in to hear the sounds and sights of the forest. The lodge was comfortable and the food was great. The research talks in the evenings were a great pre-dinner ritual for us. Do check them out. Saul was an amazing guide - friendly, fun, knowledgeable and very tuned to the rainforest. He could pick up on slight sounds and movements and helped us spot some great wildlife. Read all

TRC is up close with nature deep inside the Peruvian Amazon. If you are a fan of wildlife and love being in the nature this is the place for you. This is an eco lodge, so come with similar expectations. The sound of macaws flying over would make your day. TRC is doing some amazing work on Macaw conservation, the visits to the clay lick would be special. During your journey you would be able to spot a number of animals, birds. Do not miss the guided walks, you would really see a lot of monkeys. If you are a photographer, invest in a good zoom lens ( it will pay you back). The other thing is the amazing staff that take care of you. The food is among the very best I tasted in Peru and they really pamper you. So make sure you walk a lot to burn the additional calories :) Starting from the booking to the pickup in the airport everything is meticulously planned. From Mariella of the booking team, Juan Carlos the guide and Tania, our manager in the hotel everyone was fantastic. Ultimately spotting wild animals is a lot of luck, but this would be a great experience. Rooms: Rooms are large, spacious with wide open balconies, but no monkeys come in ( they strictly don't encourage wildlife feeding). Nearby activities: Lots of them, morning hikes, afternoon hikes, sunset cruise Walkability: You need to walk a bit, so you need to be mobile Food & drinks: Awesome Buffet, great food. Read all

The immersion experience was great. Be prepared though to feel hot and full of bug spray much of the time. Wear hiking pants. Not Lulu leggings (too hot). The guides are great and you can do as much or as little as you want. We saw a lot of animals. Read all

Posadas Amazonas is an eco-friendly lodge that makes a huge commitment to preserving the rainforest for generations to come. The food served (breakfast, lunch and dinner) is fresh and delicious! The staff is extremely knowledgeable and caring. A special shoutout to the lodge manager Cesar for ensuring that we had packed meals for the onward journey when we were delayed by a rain storm. The main attractions apart from the abundant wildlife are the canopy tower and nearby Oxbow lake. The canopy tower gives a great 360 degree view of the rainforest and we were fortunate to see monkeys and macaws from the vantage point. At the Oxbow lake we saw river otters and Caimans and we were able to catch a piranha fish as well. Overall, Posada Amazonas is a great lodge owned and operated by the native communities located in the amazing Amazon rainforest. Read all

I had an amazing time here. I was traveling solo and did 4 days/3 nights through Inca Expert Travel. It was an unforgettable experience! I opted for a group tour for the excursions and am glad I did. Our guide, Boris, was fantastic and made sure we saw as much wildlife as possible. I can't say enough good things about him. The rest of the staff were also very kind. I enjoyed the large variety of fresh food at each meal. I felt safe and well-taken care of the entire time. Read all

TRC was an amazing place to stay. Being in the Amazon rainforest was truly like no other trip I have or will ever take. From arrival we were greeted by staff with cool drinks, warm welcomes. Beautiful main area w bar, sofas, tables,games. Our guide Fernando was SO knowledgeable, interesting, enthusiastic,. We already miss his smile and laugh :) We did every excursion available over our 4 days there. The night hike turned out to be our favorite as we spotted the wandering spider then and many other intersting moths/insects. January is hot and humid, so yes expect to be wet,sweaty. Pack extra bag for wet stinky clothes ... Be ok w insects as no 4th wall in your rooms so at night mosquitio nets do a good job preventing bugs in your bed but when you wake up to use bathroom excpect moths, grasshopppers etc in room. All harmless!! TRC does provide nice rainboots for wet swampy treks.. Read all

A perfect experience in the Amazon. Harry, our guide, made the entire experience very memorable. The food is good, the bar is expensive but good and the support staff were excellent. Tanya, the manager, took care of all our needs and was very supportive the entire stay. Please remember that the rooms are open to the nature and therefore comes with its pros and cons. You wake up with the nature including the mosquitos :) The experiences offered by the Refugio is fantastic and provides a great exposure to the Amazon. Dont miss the Macaw trip. It is just magical.

This is a once-in-a-lifetime experience! From the getgo, it was easy to coordinate our 4-day stay at Tambopata. The booking was all done via email with quick responses, there was clear communication leading up to our stay and even upon arrival the staff was extremely organized (incl. taking our bags and making sure they arrived to our rooms). During our stay the staff was all very friendly and accomodating, the lodge was always clean (actually impressively clean given it is located in the jungle), and the food was great and plentiful. By far the best part of our stay was our tour guide, Saul. Upon arrival, Saul helped us pick our activities based on what animals we wanted to see (using his 10 years of experience). He worked on timing to make sure we can see as much as possible, was extremely knowledgable on the rainforest, the plants, the insects and the animals and noticeably put in the extra effort to find animals. You can tell that he truly loves his job and was always equally as excited to see the animals as us, even though he has seen them thousands of times. He helped us find monkeys, birds, countless insects, lizards, capybaras ect. I am 100% confident our experience wouldn't be the same without him. He even helped us capture these cool photos with only our iphone!! If you are planning to stay are TRC, I would highly recommend asking for Saul as a tour guide, if possible. Read all
