Posted November 27, 2019, the day before Thanksgiving

All the ones we find are inside the home/office. They come out at night. one came out yesterday so perhaps Thanksgiving is a time they come out? Or it may be coincidental.

Their bodies have pinchers (graspers) to impale, grab, slice, and dissect their prey. Yet to humans they are totally and completely tame. Since this tailless whip scorpion was on the steps, I had to move it quickly before someone walking down the steps would step on it by accident.

In the FLAAR Mesoamerica office we prefer no insecticide (except for mosquitos), no pesticides, and we prefer not to kill any spider nor tear down their cobwebs (because they help eat mosquitos without needing insecticide).

So I let the tailless whip scorpion out in the garden.

Amblypygi is the order; then there are families, and within each family genera, and then species. Since there are 155 species we will let Amblypygi specialists identify these from Guatemala City, altitude 1500 meters. These are not insects (no wings, for example).

Insects, arachnids and all their relatives are definitely of interest to me. I like to seek, find, photograph, document, and publish as many insects, arachnids and their relatives as possible.

These creatures are a sample of what was photographed by FLAAR Mesoamerica between 2018 and 2019 in cooperation with the park administrators IDAEH and CONAP. These insects are already known. But we feel there is potential for discovering lots more.

Parque Nacional Yaxha Nakum Naranjo has potential for finding and photographing creatures not documented elsewhere in Peten because of the series of lakes, lagoons, rivers, swamps, and seasonally inundated ecosystems.

We have recently found, photographed, and published Tasiste palm for Yaxha, Nakum, and Naranjo sectors of the park. This palm is well known for Belize but is nowhere documented for Tikal in any list that we have seen published in the recent half century. Why in PNYNN and not at Tikal? Because the FLAAR Mesoamerica team has found ecosystems west of Yaxha and east of Nakum, habitats which do not exist at the Tikal park. And with the help of Naranjo sector team of Archaeologist Vilma Fialko, Arquitecto Raul Norega, plus Horacio Palacios, they took us to explore a savanna-cibal-jimbal ecosystem adjacent to Naranjo which is not present at Tikal. Plus, the corozera between the savanna and the Naranjo pyramids, temples, and palaces is also different than the corozera 4 km from Yaxha and the other corozera 4 km from Nakum.

So with these unique and biodiverse ecosystems, we feel there is potential to find insects not previously photographed or published for nearby Tikal nor elsewhere in Peten.

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.

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.
