It’s not only carnivorous plants that bugs have to watch out for. Sure, if an ant tumbles into a pitcher plant or a spider stands in the open maw of a Venus flytrap, we know what’s coming next.

But certain innocent-looking plants — perhaps very many of them, even including ones in your own yard — murder hosts of insects that they have no plans to eat.

They lure passing bugs into a slow death, then exchange their corpses with other insects for protection.

One of these plants is the serpentine columbine, or Aquilegia eximia (image on the left). Native to California, it grows downward-hanging blossoms in fiery hues.

The plant is covered all over in fine hairs, or trichomes, each with a gluey droplet at its tip. Like flypaper, these sticky plants ensnare many of the tiny creatures that are unfortunate enough to land there.

By June, a single stem of serpentine columbine may hold the corpses of hundreds of bugs, write UC Davis graduate student Eric LoPresti and his coauthors.

These bugs have been called “tourists” because they don’t live on the plant or need to be there; they’re just making an ill-fated visit. (This makes the sticky plant, the authors note, an actual “tourist trap.” Ahem.)

These adhesive death traps are common in the plant world. Scientists have noticed that the corpse-covered plants can attract other, predatory insects that are looking for food.

And while they’re in the neighborhood, these predators might eat some of the plant’s pests—critters that haven’t gotten caught in the flypaper but are happily munching on the their host’s leaves and flowers. One study of a sticky daisy found that these predators were helpful to the plant.

But have the plants engineered the whole thing? Or is bedazzling themselves with bug bodies just a happy accident?

Continue reading

LoPresti studied columbine plants growing in a California reserve to learn more. Researchers marked 50 plants, then used delicate forceps to remove every trapped bug from half the plants.

They returned several times throughout the summer to pick off new corpses and to note whether the plants had been damaged by caterpillars.

One caterpillar called Heliothis phloxiphaga is fond of chewing up the columbine’s buds, flowers and fruit.

When the researchers checked on the plants, they found 74 percent more predatory bugs (such as spiders, assassin bugs, and stilt bugs) on corpse-covered plants than on clean ones.

Aquilegia Eximia

These predators had presumably stopped by for the free meal, but were also killing caterpillars or eating their eggs.

Plants with their corpses removed were more than twice as likely to have damage from pests.

The predatory bugs were helping to protect columbines. But it still wasn’t clear whether the columbine was as passive in all this as a piece of flypaper.

So in a second experiment, the researchers placed petri dishes along a meadow.

Half the dishes held pieces of columbine stem and leaf, and the other half were empty. Mesh covered all the petri dishes, making their contents invisible. Bugs that visited got trapped in the mesh, which let researchers count them later.

After just 24 hours, dishes hiding columbine clippings had trapped 21 percent more bugs in their mesh than the empty dishes.

This was “pretty unexpected,” LoPresti says, “though it makes perfect sense.”

All kinds of plants are known to send out chemical signals.

For example, leaves that are being chewed by pests may emit alarm cues that attract predatory insects, or that tell neighboring leaves to crank up their own chemical defenses.

So it’s not unheard of for plants to summon insects by sending scents onto the breeze.

Aquilegia Eximia

But it is news to scientists that plants like the columbine will lure innocent bystanders just to die on their stems.

LoPresti calls the columbine’s apparent chemical signal a “siren song.” Come visit, it calls to passing bugs. There’s no food for you here but it’ll be nice anyway. You definitely won’t be glued down and eventually eaten.

Surveying the literature, LoPresti and his coauthors found more than 110 types of plants that trap bugs on sticky surfaces.

A few of these plants are outright carnivores; they absorb nutrients from these bug corpses for their own use. But most, like the columbine, seem innocent at first glance.

Aquilegia Eximia

LoPresti wants to test more of these plants and find out whether they also use trapped corpses to indirectly defend themselves from pests.

It’s also possible that the stickiness is an accident in certain plants, he says, evolved for some purpose other than murder.

“The coolest part about the commonness is that it is not just one evolutionary lineage,” LoPresti says.

The sticky plants aren’t all relatives. Rather, flypaper plants seem to have evolved more than 100 separate times. They may all make different gluey compounds. But whatever siren songs they’re sending out, bugs would be better off ignoring them.

DO PLANTS HAVE INTELLIGENCE? Latest research indicates they do

Plants have between 15 and 20 senses, some of them analogous to our five senses. ~~~ Plants are able to sense and respond to light, water, gravity, temperature, soil structure, nutrients, toxins, microbes, herbivores, and chemical signals from other plants. This could not be done without an informational processing system. ~~~ They can form alliances with insects to use them as bodyguards, and when threatened by predators, they can summon them by using chemical signals. ~~~ They can get useful insects hooked on the drugs they make. ~~~ They use chemical warfare to fight enemies. ~~~ READ MORE fascinating facts about plant intelligence by clicking on these flowers..

THE CONNECTION BETWEEN MENTAL ILLNESS AND ISLAM - What science says about it

The sciences of GENETICS and EPIGENTICS demonstrate that human EVOLUTION is still ongoing. ~~~ Changes in the human genome occur as a result of many factors in the physical and cultural environment. ~~~ Studies demonstrate that GENETIC CHANGES occur even during the lifetime of a person, and they can be inherited by their children. ~~~ In the case of ISLAM we have to consider 14 centuries of harsh indoctrination and cultural violence, repressed normal sexuality, and a lifestyle rooted in 7th century Arabia, in sharp conflict with 21st century science and culture. ~~~ MUSLIM UPBRINGING includes mental and physical abuse, and often sexual abuse of boys and girls as well. - The INBREEDING factor is also significant. Marriages to first cousins are very common, resulting too often in children with physical and mental disabilities. ~~~ The incidence of MENTAL ILLNESS and mental disability among Muslims has been all but ignored by countries that are importing millions of Muslim migrants. - This genetic factor may explain why second and third generation of Western Muslims have difficulty controliing emotions, and sometimes engage in actions of extreme violence.

SKINNING AND OFTEN COOKING DOGS AND CATS ALIVE IN CHINA AND OTHER S.E. ASIAN COUNTRIES

It is disturbing that countries with thousands of years of civilization allow the torture of dogs and cats to be used for FOOD and the FUR INDUSTRY. - This is LEGAL in China and acceptable practice in Vietnam, Cambodia, and other S.E. Asian countries. - We have trade, diplomatic, and educational links with those nations, and in this way we are also indirectly COMPLICIT with this horror. - Hundreds of thousands of DOGS and CATS are tortured this way each year. - This PHOTO shows a puppy at a dog market in China (probably a stolen pet), lovingly pleading for attention. Later he was skinned alive. - CLICK on image to read more about this inhumane tradition, and to see related images, including those of dogs being boiled alive.

PRIONS FROM SICK DEER CAN PASS FROM DEER TO GRASS TO COW TO HUMAN - PRIONS CAUSE BRAIN DISEASES

PRIONS (tiny disease-causing agents) from SICK DEER's urine and feces can bind to PLANT roots and then travel to stem and leaves. - PRIONS are then consumed by grazing COWS, who can pass the prion infection on to HUMANS. - WHAT IS AMAZING about this is how cows can contract a serious animal disease by way of a plant. - Prions are responsible for several serious BRAIN DISEASES in animals and humans. PRIONS cause MAD COW, Creutzfeld-Jacob, and several other brain diseases, and have been linked to ALZHEIMER'S. CLICK ON IMAGE to read more.

EARTH GRAVITY WAVES RIPPLING THROUGH THE ATMOSPHERE

The upper atmosphere is not only disturbed by SOLAR storms but by EARTH gravity waves as well - Gravity waves are born when air masses are pushed up or down by a thunderstorm, perhaps, or when wind is forced up and over a mountain range. When they reach the upper atmosphere these waves have built in amplitude and extent. They can dominate atmospheric processes sometimes threatening the reliability of Earth-based communication systems. - CLICK on image to read more and watch video of computer-generated model of gravity waves.

WHAT EARTHQUAKE AND OTHER DISASTER EXPERTS DON'T TELL YOU ABOUT NUCLEAR POWER PLANTS

READ ABOUT THE BIG ONE. Also, whether as a result of a mega-earthquake, large tsunami, electromagnetic pulse (EMP) event (from a giant solar flare or from a terror attack that would fry the power grid), NUCLEAR POWER PLANTS ARE VERY VULNERABLE TO MELTDOWN ~~~ A sustained electric power failure lasting several days would leave nuclear power plants unable to operate, unleashing a full meltdown.~~~~~ We already saw how a well-prepared country like JAPAN has been unable to bring its FUKUSHIMA nuclear power plant under control after the 2011 earthquake and tsunami, leading to a meltdown. JAPAN will continue to dump millions of gallons of extremely radioactive water into the Pacific Ocean for at least the rest of this century. ~~~ READ ABOUT PREPAREDNESS for you and your PETS.~~~ CLICK ON IMAGE to read more

YELLOWSTONE ERUPTION OR NOT - BE PREPARED FOR ANY DISASTER - List of 50 PREPPER websites

A Yellowstone geologist stated that science can predict the MEGAVOLCANO behavior only as far as two weeks into the future - nothing more. Anything could happen beyond that time frame. ~~~ But Yellowstone is not the only threat on the horizon. ~~~ There are severe WEATHER EVENTS every year. ~~~ A SOLAR FLARE or a terror attack could unleash an electomagnetic pulse event (EMP) that would fry our grid and all electronics for a long time. ~~~ And then there are EARTHQUAKES ~~~ We have witnessed how incompetent all levels of government are to deal with these situations. We are on our own. So here is an article about the threat of the Yellowstone megavolcano. The article also provides preparedness tips for you, your family,and YOUR PETS for either evacuation or for hunkering down at home for an extended period of time ~~~ It includes a LIST of 50 PREPPER websites. ~~~ Illustration: Yellowstone magma pocket - by National Park Service ~~~ CLICK ON IMAGE to read article.

WHY DO MUSLIMS HATE YOU?

A good Muslim follows the Koran and Hadith to the letter. Read how those Muslim scriptures order Muslims to DESPISE AND KILL THE INFIDEL. ~~~ Muslims regard western values as repugnant, and many see jihad as justified. ~~~ Islam is not compatible with western culture. There can be no assimilation. ~~~ Abandoning Islam, or APOSTASY, is punishable by death. ~~~ Muslims have been waging war against other people since the 7th century. ~~~ It was always CONVERT OR DIE. Countless indigenous cultures and religions across Asia and Africa have been obliterated, forced to submit to Islam. ~~~ According to conservative estimates, Islam has killed 270 MILLION non-Muslims during 14 centuries of conquest and tyranny. That makes it the biggest GENOCIDE in history. ~~~ CLICK ON IMAGE to read why Islam hates you, in their own words, and learn more about the Muslim genocide

BRITISH TAXPAYERS OUTRAGED at EU spending their money building ILLEGAL ARAB SETTLEMENTS in Israel

FOR SEVEN YEARS ISRAELI AUTHORITIES HAVE DONE NOTHING to stop the EU building of illegal Arab settlements on Jewish land ~~~~~ While Israel has frozen construction across the Green Line, and razes the tiniest house addition or Jewish unauthorized outposts on the hills, Arabs keep building ILLEGAL SETLEMENTS with impunity, and with the funding and assistance of the European Union. Those settlements are in internationally-recognized Israeli land (Area C), thus the EU is not only violating Israeli sovereignty, but its own diplomatic rules of operation in foreign countries. - These illegal Arab settlements are meant to be FACTS ON THE GROUND for the eventual Muslim takeover of Jewish land - EUROPEANS DID NOT WANT JEWS IN EUROPE and murdered MILLIONS of them. Now they don't want Jews in their ancient homeland of ISRAEL either, call them "occupiers," and demand that the land be given to descendants of Muslims who invaded Israel in the 7th century. - The EU (inspired by the Nazi boycotts against Jews) already labels and boycotts products from the Jewish heartland - THE EU WAR AGAINST THE JEWS persists as they contract out the Arabs to continue Hitler's mission of killing Jews. Europe and the United States are the main funders of the Palestinian Authority, contributing to salaries paid to terrorists who murder innocent Israelis..CLICK ON IMAGE TO READ ARTICLE AND WATCH VIDEO

ISIS PLAN FOR INFILTRATING EUROPE AS REFUGEES

Along with Muslim refugees pouring into Europe there is a significant percentage of terrorists from ISIS and other Muslim factions. About 75% of those migrants are young men of military age. - This invasion follows ISIS threat earlier this year to flood Europe with HALF A MILLION MIGRANTS to unleash chaos. - The sudden spike in migration to Europe has been well orchestrated behind the scenes with the willing cooperation of Europeans. ~~~~~~~ Here we have a PERFECT STORM. (1) European leftist political elites need to expand their voting base with benefits-dependent migrants. (2) Business looks forward to cheap labor. (3) Leftists and media blatantly manipulate European shame for the Holocaust. Anyone opposed to this invasion is branded a RACIST.. - Basic math predicts an eventual demographic takeover of Europe by Islam. - The cartoon here has a an immigration officer asking jihadists "Anything to declare?" while they invade Europe - CLICK on image to read more

SATIRE - WHAT THE U.S. AND EU REALLY MEAN BY LAND FOR PEACE

Europe and the US commiserate for the loss of 6 million Jews during the Holocaust. - But they obsessively demand that Israel be partitioned along borders only 9 miles wide at their narrowest point. - These borders and the creation of ANOTHER ARAB TERROR STATE under ISIS or Iran's influence will certainly lead to a Holocaust of 6 million Israeli Jews. - On this SATIRE White House aides promise that if the Arabs massacre the Jews in a shrunk Israel, Israelis should take comfort in the fact that the world will have an annual commemoration of their sacrifice for peace. - Image from Israel Matzav blog - CLICK on picture to read article.

IF JESUS LIVED IN JUDEA TODAY

Jesus would be called a "SETTLER" and Arabs would deny him access to Temple Mount (where Muslim conquerors erected a mosque), and to much of Judea and Samaria (West Bank), today under the control of the Palestinian Authority (PA) where no Jews are allowed. ~~~ Jews who have ventured into the PA have been LYNCHED. ~~~ Jesus would not be safe anywhere in Israel. He would be pelted with ROCKS or STABBED for being a "settler". Or he would be DECAPITATED, as Arabs did to four rabbis praying at a Jerusalem synagogue in 2014. ~~~ If Jesus were a child he would be BURNED BY FIREBOMBS (as Arabs did to a child in December 2014), or have his THROAT SLASHED in his own home, as Arabs did to the Fogel children. ~~~ CLICK on image to read more about the Muslim war against Jews and Christians in today's Judea and Samaria.

Puppies live only a few months inside cages before being slaughtered, gone INSANE from cruel treatment. ~~~ A few adult animals spend their entire lives inside cages breeding more puppies. ~~~ See photos of CHINESE WORKERS GRINNING as they immobilize puppies by ELECTROCUTION and then skin them alive. ~~~ After that the tortured animals are tossed on a pile to AGONIZE IN EXCRUTIATING PAIN. ~~~ This is all LEGAL in China. ~~~ In S.E. Asian countries with animal welfare laws, they are not enforced. ~~~ The West buys these furs because they are classified as belonging to "RACOON DOGS" (relatives of dogs) and not to dogs.. ~~~ PETITIONS are not enough. ~~~ The fur trade in the West must be stopped altogether. ~~~ CLICK ON IMAGE to read story and see heartbreaking photos and VIDEO from inside a Chinese fur farm.

THE MAGIC AND MYSTERY OF CAVES

IT ALL STARTED WITH A MEATBALL

Arthur was a stray dog who decided to join a European Peak Performance Team during their treck through the jungle in South America. It all started when one of the members gave him a meatball.
