Most biological and ecological research in Peten (Guatemala) is undertaken at Parque Nacional Tikal or at El Mirador to the north. Research is popular at Tikal since you can reach it on a paved highway; there are three hotels to chose from, and there are roads throughout the center of the park.
We (FLAAR Mesoamerica) also recognize the pleasant aspects of Tikal (I was a student volunteer here for 12 months back in 1965). But my heart and soul are in the Yaxha and Nakum area. And, courtesy of Archaeologist Vilma Fialko and Arquitecto Raul Norega, plus Horacio Palacios, another key person who has hiked through all the remote areas of the Naranjo sector of Parque Nacional Yaxha Nakum Naranjo, I am now learning of the remarkable biodiversity of the ecosystems of the Naranjo sector of PNYNN.
Insects and arachnids and all their relatives are of definitely interest to me. We also seek, find, photograph, and document birds: park ranger Teco showed me king vultures soaring above the hills in the park. In 54 years in Mesoamerica I had never seen a king vulture in the wild (only in a zoo). But all the bird species have been carefully documented in Tikal area over recent half a century.

But Laguna Yaxha and Rio Ixtinto offer ecosystems not at Tikal, so this park (PNYNN) offers opportunities to find and photograph waterbirds (wading birds, shore birds, diving birds, and swimming birds) that have not yet been seen nor photographed with high-resolution digital cameras in adjacent Tikal.
While working at Parque Nacional Yaxha Nakum Naranjo we found and photographed many different sizes and shapes of native Peten area wasp nests. While visiting friends at hotel Posada Caribe (on the shore of Arroyo Petexbatun, municipio of Sayaxche, Peten, Guatemala) they took us to visit other friends of theirs several kilometers hike into the hills. We noticed a wasp nest and I took some photos: Nikon D810, 200mm tele-macro lens.
As soon as we can identify the Genus species of these wasps we will update this post.
View of entire nest, several kilometers from Arroyo Petexbatun.
View of how nest is attached to underside of banana leaf.
Close-up to show the entrance to the nest.
Another angle of view to see the entrance to the nest.
We do not have any photographs of the inside since we do not destroy the nests; we leave them fully operational just the way we found them.
Wasps are among my favorite insects because of their biodiversity of size, nest architecture, and whether they are pollinators. For example, we hope to find more honey wasps (the ones in this photo are not honey wasps). Guatemala is a great place to study insects and arachnids.
In the gardens, parks and forests of Guatemala, it’s common to appreciate the most famous pollinator: the bee. It’s likely that if you observe a bee, it’s Apis mellifera, which is also known as the domestic or European bee. It was introduced with the arrival of the Spaniards and has adapted very well throughout America. However, this is not our native bee.
Apis mellifera, domestic or European bee.
Our native bee, Melipona beecheii, is a stingless bee, it’s commonly known as a Mayan bee, jicote or criolla. It’s a robust bee, like the European bee, 9-10 mm long, black, orange and with yellow stripes. It’s native to Mesoamerica, in Guatemala they live at elevations of 0-2000 meters above sea level in the departments of Alta Verapaz, Baja Verapaz, Chiquimula, Quiché, Petén, Escuintla, Guatemala, Jutiapa, Retalhuleu, Sololá, Santa Rosa and Izabal(Escobedo, and others, 2017).
Our continuing research in PNYNN finds trees, bushes, mushrooms that are not yet in any list of flora of this part of Peten (this park is between Tikal on the west and Belize near the east). Although our focus is on finding edible native plants and plants to provide materials for the Maya for thousands of years, we also do photography of birds (especially waterbirds), spiders, and insects.

Here are photos of the same Genus species in four different locations around Naranjo ruins and from Naranjo to Rio Holmul (about 20 kilometers to the north).
On the July field trip our team found lots of giant grasshoppers. These are solitary (meaning never in a group). Their bodies look as if they are totally armored to withstand attack from birds and other insectivorous creatures. We will do a web page on them and also a full-color PDF as soon as possible.
The Yaxha-Nakum-Naranjo National Park is considered a wetland of great importance for nature and human beings due to the diverse ecosystem services it presents. Ecosystem services are given thanks to the roles played by various agents in the ecosystem.
Aquatic birds are an essential part of ecosystems and provide specific ecosystem services, such as:
Provision of food for predators.
Provision of feathers as ornament.
Control of diseases thanks to the fact that some of them are scavengers.
Bird-watching.
Control of plant growth by foraging.
Seed dispersal and pollination.
Control of populations of fish, crustaceans, insects, etc.
The felines, family Felidae G.Fischer, 1817, are carnivorous mammals with very well-developed senses, especially hearing and sight. They are recognized for being supreme predators and excellent hunters. They have soft fur with colors that help them camouflage, they also have a short muzzle and a long tail.
In Guatemala, besides the domestic cat, there are other 5 felines, which are native.
From genus Leopardus:
Leopardus pardalis Linnaeus, 1758 – Ocelot
They are the largest feline of this genus with a body weight of up to 16 kg and a length between 65 and 97 cm. The coat on its belly is white and the rest of the body is yellowish or reddish cream with black rosettes. They inhabit tropical forests, savannas and mangroves.
