Anti-Gravity Properties of Beetle Wings?

At art fairs, people often ask me biology questions. Some even follow up later. Here is an interesting, confusing (confused?) one: 'Anyway, meeting you, a real life beetle entomologist, reminded me of the fascinating (real or imagined?) work of Russian scientist/inventor Viktor Grebennikov.  He wrote about investigating apparent anti-gravity properties of beetle wings and wing covers, and even applying them and their surface geometries to make several generations of a flying device.  Maybe it’s real, maybe it’s fantasy. Maybe he successfully passed this technology on to the Russian scientific establishment, and maybe it is the basis of alleged UFO sightings, or the advanced hypersonic weapons or the nuclear powered cruise missiles announced by Putin that can linger in the air indefinitely.  I don’t know.   But it might be interesting to try replicating some of his early experiments using beetle wings from your collection.  

As I told you, I’ve felt a weird sensation in my hand when Tucson june bugs took off, and it didn’t really feel like wing vibrations.  And my collaborator has told me about several strange observations that he has made, in tiny bugs and a spider, that seem to point towards some kind of non-gravitic force.  He has found entomologist reports of similar strange insect behaviors that they could not convincingly explain with known physics.'

I am not sure what anti-gravity means, and I have not read Grebennikov's papers. But: Close to a big mass like earth everything is exposed to its gravity. Flying or in water floating becomes possible in our atmosphere if the pressure of the air or water column under any object is considerably larger than that above it. The profile of wings moving through air can produce turbulence and pressure differences over its surfaces that produce updrift - check out diagrams of bird or airplane wings. Beetles use only their membraneous hind-wings for flight, the hard-shell front-wings are in my opinion just a protective cover (see the pre-flight image of a Lined June Bug above). I am sure that  the membranous beetle hind-wings function in a very similar way to other wings, with the heavy vein-structures in front probably producing the necessary turbulence. So I expect no miraculous change of basic laws of physics here. The heavy front-wings (elytra) seem to be mainly a protective shield for the delicate hind wings and other organs when the beetle is not flying, and beetles spend really a lot of time grounded when you compare them to many other insects. I have seen suggestions that those wings are used to facilitate flying when they are open. Maybe like a gliding apparatus? But seeing that most beetles are pretty bad fliers compared to their relatives like hymenopterans, dipterans and the 'primitive' odonata, I doubt that the stiff, heavy elytra are helping them fly. Several beetle families that fly well have greatly reduced elytra - Staphylinids and  Ripiphoridae  for example. The next photo is of Ripiphorus rex, a very bee-like beetle that appeared in another blog (https://arizonabeetlesbugsbirdsandmore.blogspot.com/2011/04/wasp-bee-fly-its-ripiphorus-vierecki.html)

Others like buprestids and some Chafers do not lift their front-wings but only push their hind-wings through lateral slits when they want to fly. Thus their body seem to keep a more airodynamic shape. They fly fast and maneuver well, land without those clumpsy crashes of their close relatives, and in addition often resemble very good fliers among Hymenopterans like wasps or bumblebees, probably a mimicry for predator avoidance. next photo: Euphoria monticola, a Flower Chafer, flying with closed front-wings

As for mysterious vibrations that you feel before a big beetle lifts off: Insects are heterotherm, not maintaining a constantly elevated bodytemperature as mammals and birds do. But their flightmusculature only functions within certain, optimal temperature range. Some big moths (Sphinx Moths), big Hymenoptera (bumblebees), and big beetles can 'shiver' to produce extra heat and also increase the pumping motion that ventilates their tracheal system. They do that as flight preparation. So no - I do not believe that beetle wings are 'anti gravity devices' Sorry to be so tied to conventional physics, living under constant gravity does that to a mind!

Vitrification versus Maceration

A couple of weeks ago, I participated in the SW Kiln Conference in Safford AZ. It was masterfully arranged by Andy Ward on the grounds of the East AZ College at Discovery Park, complete with lectures, demos, and of course about a dozen firing ventures.

Kira loves crowds of nice people, pottery events and fire, so she got to go too

She behaved well, usually just following me around or greeting folks. But then she took off across an empty lot towards what? A log dropped by the wood collecting crew for the kilns? No, she would not enthusiastically roll on wood. Well, it turned out to be her early contribution to halloween, luckily so mummified that she didn't even pick up a stink, at least not for our human noses. She herself felt obviously great about her new perfume. Now I wanted the interesting scull of the mummy, but it was so hard and leathery that not even super sharp stone flakes from the arrow tip makers could cut through it. So I packed up the entire thing. Surprisingly, this group of people accepted my goulish idea as normal enough and contributed advice and packing material. Bill Warner suggested to soak the mummy in a strong lye of wood ash and water. From my own kiln experiments I have lots of fine ash. So at home, I made the concoction rather strong - it discouraged the coyotes that opened up my bucket during the first night but then never returned. Today I finally gathered my courage and fished a now pretty clean scull from the stinking brew. From the lye I moved it to a chlorine bath and then hydrogen peroxide. Whatever killed this animal - now it's nicely sterilized. To my naturalist friends: whose scull is it? To all others: Happy Halloween!

Mating Dance of the Desert Leaf Cutter Ant

September 20, 2025. Four and three nights ago we finally got some measurable rain. Two days ago, our Leaf-cutter Ants swarmed and danced in the early morning hours. As every time I spot this event, so probably once a year, the column of dancers rises and falls over a Thuja tree (Conifer like a cedar) in our drive way. One big old colony lives not far from it under an Ironwood. The dancers probably come together from several nests in the area. I know that I would find other dancing swarms simultaneously further down the road (this is a community with dirt roads, losely spaced houses, and mainly desert or not-at-all-landscaped yards.

These non-sting ants (Desert Leaf-cutting Ant (Acromyrmex versicolor)) live quietly in populous communities deep under ground with extensive fungus-growing chambers. Ever now and then they will venture out, cut leaves, carry them home and compost them under ground for their fungus gardens. (denuded bushes usually are not killed but rejuvenated. The larger Atta species in Central America can cause financial set backs for owners of teak plantations because the wood production is slowed down by the loss of leaves. But in a normal desert garden, the occasional raids of our small Acromyrmex are usually not more than a nuisance) When the weather is 'bad' too dry, too hot .... the ants close their entrances and stay hidden for months.

BTW, the characteristic cone shaped structures often seen are not nest entrances but heaps of sand that is expelled when new fungus chambers are built.

Of course, the entire dance party serves bringing nubile females and males together. The mature colony produces those about once every year and releases them all at once after a certain trigger, a good monsoon rain in this case. The sexes find each other up in the air, but then the 'bonded couples' or rather groups of one female with several males usually sink to the ground together .... This time I got the inpression that there were fewer females than normal .. annecdotal but possible in the current stress situation

A Rattling Complication

Yesterday evening Chaco snake-barked and I had to relocate a small rattler from the patio. Before releasing my captures, I often take their portrait. This one was rather small, so I thougt one of my replica pots decorated with big double spirals would make the perfect complement to the coiled snake. At first, the reptile wasn't having any of it and was determined to leave in a straight line away from me and my pot.

It took a lot of convincing and stacking and restacking the unwilling star of the photoshoot before he agreed to sit, and coil up, next to one of the large black and white spirals on the Tularosa Black on White (or Cibola White Ware) Pot. But the pot was absorbing the early morning sun and the snake had had a chilly night. So eventually he snuggled up against the pot and I got some photos.

I like this one best that I took in my own cast shadow to avoid too much distraction from slanting light and body shadows of pot and snake. Also, the snake is coiled up right next to the spiral pattern which was the initial inspiration for the imprompto photo shoot

But Snek now developed ideas of his own and began to investigate the big warm object next to him. Are there ancient memories in the genes of his tribe of living next to pots like this in ruins of the Southwest and even further back of indigenous people who made pots like this?

Now he seemed very comfortable, very familiar with the set-up. He explored ...

He found the entrance, slid in and settled in. A retreat made for his size. I could just see him shuffling his coils, resting his head close to the exit.

There was no way to convince him to give up his cave. He felt safe and cozy. He gave a relaxed little buzz when I pked him with a stick. He never bothered to strike. He felt at home. Iwould have to leave my pretious pot out there in the State Trust Land until he decided to leave on his own, just hoping that nobody would find it. I could just imagine the outcome if someone did: A shriek, a dropped, broken pot, maybe a bitten finger? Eventually I ran home to get my lizard-stick, thin, with a noose made from fishing line. With it, I managed to pull him out of the pot, only to find out that it takes handling the caught critter, usually a small lizard, to open the noose and release the victim. To do this with the snake, I had to run home again and fetch a heamostat to hold the head and my little nail scissors to cut the thread. All good now, snake indignant but free, pot home with me, I maybe a little smarter?

Size matters!

Size matters! If the pony was the size of a beetle - that would be an easy keeper! If the beetle was the size of a pony, I would saddle him and fly! (actual size of my latest mud pony and Palo Verde Root borer, no photo montage. The stuff to do when it's too cold to go 'bugging') Actually - if a homoiotherm animal like a pony was that small, it would have to live on a high caloric diet and eat constantly, more so than a hummingbird. So no easy keeper at all. And a huge, rideable beetle would suffer from oxygen deprivation even at ground level, much less high up in the air. Bummer!

Coyote Buddies

Here in nw Tucson our coyotes are very vocal and active right now (mating season). A few days ago my heeler visited our neighbor and returned from there playing with a coyote girl that he has known for a couple of years. She was following him up our long drive way, but she has a partner now who was not happy with that. His hackles were up and he chased my heeler off. But then she ran after the dog again, so he made playful moves at her again, until her mate rebuffed him again. All the time the trio was moving towards me and my leashed Aussie who was barking angrily. Finally the male coyote had enough and drove his girl off, and my heeler joined me to go inside. Very clearly, hackles were raised but no further aggression. Pretty soon all of them, coyotes and my 3 dogs were howling, just separated by our dog run fence that the coyotes could easily scale, but they never have in 23 years and several generations of dogs. Our little adventure inspired me to make a coyote of my local wild clay
