Chrysina :
Ce sont des RUTELINAE : griffes inégales et articulées, en particulier sur les pattes postérieures !
Ce sont des RUTELINI : labre horizontal, n'adhérant que peu au clypéus !
Ce sont des Chrysina : bord externe de la mandibule non échancré :
Et
: Le quatrième article des tarses des pattes postérieures porte une saillie
pointue et dentelée sur l'angle ventral et 2 éperons de chaque côté qui sont de
longueur et d'épaisseur différentes Les belles "américaines" !
Now I regard species of Chrysina at my lights simply as
old friends and no longer feel the urge to collect them in long series, if
at all. I have heard stories of collectors and dealers with considerably
less restraint collecting hundreds of specimens from the same mountain
canyons, year after year. This annual carnage has led some people to wonder
out loud whether or not Arizona’s Chrysina are in real need of some
sort of legal protection. Nearly 30 years ago, Arnett and Jacques (1981)
declared that both C. beyeri and C. gloriosa,
which they mistakenly thought were the only species in the United States,
were “…endangered and should not be collected.” However, on a warm and dry
night in Madera Canyon this past July, all three species of Arizona’s Chrysina turned up at my light in good numbers. One species, C.
gloriosa, was there in incredible abundance. Still, it would be
worthwhile for a university or governmental agency to study the overall
impact of intensive collecting on Chrysina populations in Madera
Canyon and other popular collecting sites in southeastern Arizona.

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.

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
