Gleaming beetles from Central America attract insect enthusiasts and offer hope for saving a priceless habitat.

In a world among the clouds, entomologist David
Hawks and I keep watch for the brilliant jewel scarabs of Honduras’s
tropical montane forests. We wait like fishermen with nets cast,
standing beside lighted white bedsheets spread on the ground. When the
jewels fly in, raining color against the cloth, we feel like kids again.
We collect jewel scarabs—to estimate their
population sizes and study their ecology and distribution. Dave joined
me here in 1992, bringing his passion for jewels with him. Since then we
and others have found seven new species in Honduras, and we rediscovered
a species once thought extinct.
Not surprisingly, scarabs have also seduced
commercial collectors. While many sell for a few dollars, a bright red
specimen might fetch $200, the finest gold, $500. With such a bounty on
scarab heads, some conservationists worry that populations could be
depleted. But our research suggests otherwise.
Catching insects isn’t like hunting jaguars.
Millions of jewel scarab eggs, larvae, and pupae remain underground,
while collectors take only adults. Meanwhile, the journey to scarab
habitat weeds out all but the most determined. Many cloud forests are a
strenuous trek away; others require a helicopter.
The biggest threat to scarabs is not insect
hobbyists but loss of habitat as tropical forests are converted to
farms. We believe that regulated beetle collecting by local people—and,
in time, beetle farming—could actually help slow this process. It has
been successful elsewhere with butterflies and other insects.
If a cottage industry developed, some local
people might find that a treeless patch of land is worth less in the
long run than a standing forest full of jewels.
Get the whole story in the pages of
National Geographic
magazine.

A shining example of a jewel scarab beetle, Chrysina strasseni hangs out on a leaf in Honduras’s Pico Pijol National Park. Jewel scarabs are favorites of many insect collectors, who will pay $5 to $500 apiece, depending on the specimen. A perfect C. strasseni might go for $200, but this one was collected for science, not for sale.

A
Chrysina quetzalcoatli is freed in Cusuco National Park,
leaving a fecal trail. “They almost always do that before they
take off,” says entomologist David Hawks. Hawks and collaborator
Ronald Cave are estimating population sizes of jewel scarabs in
order to assess how collecting by scientists and bug enthusiasts
may affect beetle numbers.

Chrysina cavei was named by entomologist David Hawks of the University of California at Riverside after collaborator and friend Ronald Cave. “Ron always seems to be cold and bundled up when we’re working in the cloud forests,” says Hawks. “This species’ blue tarsi remind me of Ron’s perpetual cold feet!”

Dotted with gold, Chrysina spectabilis was thought to be extinct when scientists found populations thriving in the pine and oak forests of Cusuco National Park in Honduras. One of the largest of the jewel species, the beetle’s “spots” are actually shallow impressions that appear gold because of structure, not pigmentation.

An
iridescent jewel, Chrysina victorina from Oaxaca, Mexico,
was one of the first described species of jewel scarabs. Says
entoentomologist David Hawks of the fluorescent green beetle:
“There’s no special light behind it. It just seems to glow.”

Le rêve !
You may well ask “Just what the heck is a weevil person doing writing an article in Scarabs?”
Well, this past summer I had the opportunity to visit the southern state of Chiapas, México and on one fine sunny day high in the mountains I experienced what can only be described as the scarab collector’s wet dream! Let me tell you about it. For a number of years I have been working in Chiapas in collaboration with ECOSUR, a small college located in San Cristobal de las Casas in the Altos of Chiapas. My project has been surveying the leaf litter inhabiting weevils of mid and high elevation forests. We’ve been fortunate to visit and sample numerous forests, some only small fragments, and many otherwise inaccessible unless one has proper permission from the indigenous inhabitants. Often this requires meetings with officials from the local ejido, then a town meeting to approve permission. But enough of logistics, let’s get to the real story!One area we have worked is the La Sepultura Biosphere Reserve, located about 25 kilometers southwest of the town of Villaflores in the Sierra Madre de Chiapas of western Chiapas. We work out of a small town named Sierra Morena at about 1,200 meters elevation. Sierra Morena sits in a valley between two higher mountains, Cerro Bola to the south and Tres Picos to the north. Cerro Bola (16º.13464 N 93º.60077 W) is just under 2,000 meters and is a nice sharp peak with a definite summit. Leaf litter faunas change as one moves up in elevation so this one day, June 14, we thought it worthwhile to spend the 3 hours to walk up to the peak and take some samples, which we suspected would be quite different from the samples from between 1,400 meters and 1,600 meters we had previously taken. The day was sunny and the rains had not yet arrived so things were quite dry. Quite a few trees had not leafed out and the litter was dry and sandy. When we arrived at the peak we noticed that the litter here was moister, perhaps due to clouds collecting at the summit and depositing moisture in the form of mist or light rain. Within a few minutes of our arrival my keen coleopterological eye spotted a large green beetle on a leaf about 10 feet up in one of the taller trees right at the peak. I asked one of my much younger, spry and lighter colleagues if he could climb up that tree and fetch me that beetle. “Sure” he said and promptly scaled the trunk. As he reached out for the beetle he commented “There’s another one over there” and pointed to another, clearly visible on another leaf. He then noted as he scanned the upper foliage of the tree that “there are quite a few of these up here.” I approached him and peered up to get a better look. Sure enough I could now see about 10 or more beetles clinging to the branches and leaves of the tree. “Why don’t I just shake the tree and they should fall down?” he asked. I agreed that this seemed a suitable arrangement, so he shook the tree. At this point I must suggest that the true scarab enthusiast find a comfortable seat, sit down, close your eyes, relax and try to imagine this scenario. Picture the tree shaking and the large, bright green beetles falling. First one or two, then 10, 20… then a hundred, then hundreds. It was literally raining Chrysina!!

As they fell, some took wing, some hit the ground and stayed there, some ended up on my clothes and on me, some fell onto lower vegetation. Then a few seconds later, as if on some magical cue they all started to fly. At first I grabbed a few from my clothes but soon my hands were full and being a weevil guy, my biggest vial would only hold half a hind leg of one of these easts, so employing my quick PhD-given thinking skills, I decided to use one of the pillow cases that I use for bagging the leaf litter samples downhill. Stuffing the ones on my hands into the bag, I collected about 20 or so more on my body and then started picking them off the lower vegetation and ground. In all I must have grabbed about75 specimens in about 5 minutes of frenzied collecting! For every one I got, five flew away. Not to mention that the tarsal claws on these guys were like fine needles, easily piercing the skin and drawing blood when one pulled them off your arm or hand. But when one sees hundreds of Chrysina within arm’s length, pain is not a factor, right ? By now the reader will be breathing heavily and in need of a cool drink, perhaps if one is of advanced years, even a sedative or a nap. So, let me sum up. Benigno Gómez of México has confirmed the species as Chrysina triumphalis Morón. At the present time, all specimens are still in Mexico. The beetles were not mating and did not appear tobe feeding on the tree. I think it’s significant that this was at the end of the dry season and perhaps the beetles had congregated in a moister area to await the onset of rains. Even for a weevil guy, this was a very exciting day, but I can only imagine the range of raw emotions racing through the minds of you scarab collectors at this climactic moment.

Notre collègue et ami Conrad Gillett au Belize (Las Cuevas) :
But it was not only dynastids that proved to be diverse at the lights. The rutelids were alsoery impressive and consisted among others of Macropoides crassipes, Macropoidelimus mnizechi, the newly described Epichalcoplethis monzoni Soula (a few of our specimens were subsequently designated paratypes), Pelidnota belti, Pelidnota centroamericana, Pelidnota prasina (or similar species) (Figure 17). On one occasion we were able to take a portable battery powered light quite deep into the forest and this yielded Chrysina (Plusiotis) diversa, which I believe is also a new country record.
