Claims Of Insect Collapse Rubbished By New Study

Paul Homewood
Not A Lot Of People Know That

Readers will recall this story from January:
Insect collapse: ‘We are destroying our life support systems’
According to the Lister paper:
“Over the past 30 years, forest temperatures have risen 2.0 °C, and our study indicates that climate warming is the driving force behind the collapse of the forest’s food web”
As I reported at the time, the supposed temperature increase was fake, an artifact of merging two sets of incompatible data. The El Verde Field Station, responsible for the meteorological data, clearly warned against combining these two sets of temperature data, because the first one up to 1992 was artificially higher because of faulty equipment.

Any competent scientist should have double checked the source of the data, but for some reason Lister did not.

Now PNAS, who ran the original study, have published a new paper which rubbishes Lister’s findings.

Not only does this new study confirm the incompatibility of the temperature data, it also questions Lister’s claims that insect populations are even declining at all.

Tiny Spies: This Insect-Like Flying Robot is Smaller Than a Penny

Futurism

Tiny Dancer 

A team of engineers from the University of Southern California in Los Angeles built a four-winged flying robot called Bee+, which weighs just 95 grams and sports a footprint smaller than a penny.

Harvard researchers built another tiny flying robot, called RoboBee, in 2013. It weighed only 75 grams.

But RoboBee featured just two wings, which made its flight far erratic and uncontrolled. Four wings gives Bee+ a way to control pitch and its orientation in space.

Why Have Insect-Delivered Diseases Tripled Since 2004?

Catherine J. Frompovich
Activist Post

In May of 2018, the Centers for Disease Control and Prevention (CDC) published some rather interesting demographic data regarding insect-delivered diseases – basically those diseases have tripled since 2004 [1-2]!


According to the CDC, “Nine new germs spread by mosquitoes and ticks have been discovered or introduced since 2004.”  Chikungunya and Zika viruses, even though not ‘new’ and have been around elsewhere, are relatively new to the USA.

The question this author, who is/has been a healthcare issues researcher and writer since the 1980s, logically and somewhat conclusively, has to ask is, “What roles do chemtrails sprayings for Solar Radiation Modification (SRM) and the genetic modification of insects, including diseases, to be genetically modified and used as “weapons of war,[1]” play in the tripling of vector-borne diseases?”

Where have all our insects gone?

Robin Mckie
The Guardian UK

When Simon Leather was a student in the 1970s, he took a summer job as a postman and delivered mail to the villages of Kirk Hammerton and Green Hammerton in North Yorkshire. He recalls his early morning walks through its lanes, past the porches of houses on his round. At virtually every home, he saw the same picture: windows plastered with tiger moths that had been attracted by lights the previous night and were still clinging to the glass. “It was quite a sight,” says Leather, who is now a professor of entomology at Harper Adams University in Shropshire.

But it is not a vision that he has experienced in recent years. Those tiger moths have almost disappeared. “You hardly see any, although there used to be thousands in summer and that was just a couple of villages.”

It is an intriguing story and it is likely to be repeated over the next few weeks. The start of summer is the time of year when the nation’s insects should make their presence known by coating countryside windows with their fluttering presence, and splattering themselves on car windscreens. But they are spectacularly failing to do so. Instead they are making themselves newsworthy through their absence. Britain’s insects, it seems, are disappearing.

This point was underlined last week when tweets from the naturalist and TV presenter Chris Packham went viral after he commented on the absence of insects during a weekend at his home in the New Forest. Packham said he had not seen a single butterfly in his garden, and added that he sleeps with his windows open but rarely finds craneflies or moths in his room in the morning. By contrast, they were commonplace when he was a boy. “Our generation is presiding over an ecological apocalypse and we’ve somehow or other normalised it,” he later said.

How Technology is Like Bug Sex: Supernormal Stimuli

Comment: Re-blogged from 2013.

----------------

This week, thousands of people swarmed the annual Consumer Electronics Show in Las Vegas. Looking from above, the scene resembled an insect infestation of scampering masses in a hive of the latest must-haves.

When considering our complex relationship with technology, perhaps it is useful to reflect upon the plight of one particular bug, the male julodimorpha beetle, who like us at times, can’t get enough of a bad thing. His misplaced desire is so powerful that it threatens the survival of his species.

While in flight, the male scans the dry ground of the Australian outback, looking for love. He seeks out the largest, reddest female he can find because these two traits, size and color, impart instinctual cues about the genetic fitness of his mate. Suddenly, the sight of his dream girl stops him mid-air. He composes himself and approaches the sultry beauty.

But the male of the species is not known for subtlety. Genitalia erect, he is ready for action and begins his lovemaking as soon as he lands on her. But his rude advances are rebuffed. However, he is determined to satisfy her, whether she is willing or not. He remains faithful, even as other suitable females pass him by. He wants only the biggest, the reddest and therefore, the most attractive female.

Undeterred, he keeps humping until either the sun bakes him to a crisp or the Australian Tyrant Ants cover his body and begin dismembering him limb from limb. Finally, he dies, never knowing that he unsuccessfully tried to impregnate a ravishingly beautiful bottle of beer.

A julodimorpha beetle romances a discarded beer bottle.

Supernormal Stimuli

 

To the julodimorpha beetle, the beer bottle’s size, hue, and dimpled bottom are an accentuated embodiment of female allure. His story of fatal attraction is tragic, but it is not uncommon. The phenomenon is known as “supernormal stimuli,” a term coined in the 1930s by the Dutch Nobel laureate Niko Tinbergen, to describe exaggerated features, which appeal to an animal’s evolutionary instincts but elicits stronger responses than the real thing. The behavior is seen across many species, most notably, our own.

Tinbergen experimented with small songbirds who chose to sit on large fake eggs rather than their own brood. He saw male stickleback fish attack redder decoys more ferociously than they would real invaders. He also observed some animals who regularly deceive others with the technique. For example, the cuckoo bird is known for laying her eggs in different species’ nests, confident her slightly larger and brighter-colored young will spark instinctual cues to fool the host bird. The unsuspecting mother will nourish the larger cuckoo chick, thinking it is the biggest and therefore healthiest of her brood, meanwhile her own offspring starve to death.

We’re Cuckoos Too

 

Before mocking the gullibility of beetles, birds and fish, consider our own weakness for the things we perceive to be better than the real thing. Society and technology have evolved much faster than our instincts, leaving us vulnerable to the same kinds of adverse influences. But unlike lower animals duped by parasitic species, humans sell supernormal stimulus to each other for a profit.

Harvard psychologist Deirdre Barrett asserts that the technique influences our actions just as much as it does that of other animals. Television and movies portray juiced-up versions of relationships, allowing us to experience heightened emotion, connection and excitement, without all the effort of actually, you know, doing anything.

We’re captivated by video games which provide more exhilarating and purpose-driven versions of life. Dolls, anime characters and other objects of accentuated cuteness — think Hello Kitty and Precious Moments — use biological markers of natal helplessness like large eyes, flat noses, and large heads to entice children and grownups alike to purchase and care for them. Fast food is spiked with extraordinary quantities of sugar and fat, both extremely rare in nature, but also extremely delicious.

But perhaps the most common supernormal stimuli comes piped onto our screens and more recently, into our pockets, via our various digital devices. Our species’ beer bottle to hump seems to be our hunger for simulated sexual stimulation. The illusions created by flickering light on a screen are no more real than the beer bottle is to the beetle, yet digital pornography is a multi-billion dollar industry, which up until last year, timed its own industry convention to coincide with C.E.S.

Our penchant for making pleasurable things even better is nothing new. Some of the world’s oldest works of art provide evidence for the ancient appeal of supernormal stimuli. The Venus of Willendorf, estimated to have been carved from limestone some 25,000 years ago, depicts a female figure with exaggerated features including a detailed vulva and breasts large enough to make even today’s proportionally-enhanced porn stars blush. Historians theorize that the figure is the first in a long line of objects meant to capture the eye and arouse our desires. The creator of the Venus of Willendorf was not only one of the world’s first artisans, he was also among the first marketers.

The Mother of All Stimuli

 

But ever since cavemen began their naughty cave carving, there have been counterbalances to the effects of supernormal stimuli, which separate us from easily-fooled animals. Whereas julodimorpha beetles fornicate with their beloved beer bottle until death, humans quickly wise-up, get bored and move on.
Our brains come pre-installed with a piece of mental software which makes us tire of the old and seek out the new. It’s called “hedonic adaptation,” and it is the reason why lottery winners and paraplegics tend to revert to the same levels of happiness they felt before their respective life-changing events.

We adapt to our situation and our attraction to superficial features like breast size, sugar content, or screen resolution, fades when the object(s) of our desire become commonplace. We’re in love with our latest i-thing for a while, but soon realize it’s just another addition in our growing collection of future trash. Superficial traits may draw us in, but on their own, they lose their appeal.

However, our tendency to quickly adapt leaves us vulnerable to the one supernormal stimuli we find hardest to resist. Though we may cringe at the plight of the julodimorpha beetle or the host of the cuckoo bird’s egg, we are just as mesmerized by one particular traits we find equally enticing. It is why we line-up in droves at C.E.S., Apple stores and movie theaters and it is the stimuli embedded in the stories we tell and the games we play. The ultimate supernormal stimuli, as far as our species is concerned, is novelty.

Our insatiable curiosity is perhaps humanity’s greatest virtue, but it is also the source of many of our weaknesses. Pornography addicts need increasingly stimulating imagery to reach climax, spending hours searching for just the right titillation. Compulsive gamblers must take bigger risks, and incur bigger losses, to get the same fix. These are of course extreme examples, but they illustrate how we are all, to some degree, drawn to the insatiable enchantment of “more”. The new, new thing attracts us because of its mysterious potential, not its rationalized value.

Our salvation, as Dr. Barrett writes, comes from understanding. “Once we recognize how supernormal stimuli operate, we can craft new approaches to modern predicaments. Humans have one stupendous advantage over Tinbergen’s birds — a giant brain. This gives us the unique ability to exercise self-control, override instincts that lead us astray, and extricate ourselves from civilization’s gaudy traps.” Indeed, we begin to free ourselves from the pull of supernormal stimulus when we recognize it as such.
