"Persistence and determination alone are omnipotent!"

The mirror test is an experiment developed in 1970 by psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability to recognize itself in a mirror. It is the primary indicator of self-awareness in non-human animals and marks entrance to the mirror stage by human children in developmental psychology. Animals that pass the mirror test are: Humans older than 18 mo, Chimpanzees, Bonobos, Orangutans, Gorillas, Bottlenose Dolphins, Orcas (Killer Whales), Elephants, and European Magpies. Others showing signs of self-awareness are Pigs, some Gibbons, Rhesus Macaques, Capuchin Monkeys, some Corvids (Crows & Ravens) and Pigeons w/training. (Sorry Kitty!)

3-6-18 Monarch butterfly numbers down for second year in Mexico
The population of monarch butterflies in Mexico has gone down for the second consecutive year, government officials say. In the autumn, the orange and black butterflies migrate from Canada and the US to central Mexico, where they hibernate in pine and fir trees. Every year, scientists measure the area in which the monarchs cluster. Mexico's Commissioner for Protected Areas Alejandro del Mazo said numbers had diminished by 14.8% this winter. Speaking at a news conference in Mexico City, officials said nine colonies of monarch butterflies had been recorded in Mexico in the 2017/2018 winter months, down from 13 last year. Mr del Mazo said that "extreme meteorological events" could be a leading cause in the decline of the numbers of Monarch butterflies overwintering in Mexico. World Wildlife Fund's Mexico Director Jorge Rickards said a particularly busy hurricane season across the insects' migration route, which stretches almost 5,000km (3,100 miles) from Canada to Mexico, could be a factor. "These climate phenomena without a doubt have an impact on the migration," he said. Monarchs are one of the few insects to migrate such a vast distance and scientists recently found that they use a kind of internal solar compass to guide them. While the area in which the monarch butterflies hibernate in central Mexico went up in the winter of 2015/16, the overall trend for the past two decades has been a downward one. In 1996/97 the butterflies could be found in about 18 hectares of forest in the states of Mexico and Michoacán. This past winter, only 2.48 hectares had monarch colonies.

1-11-18 Meet the butterflies from 200 million years ago
Newly discovered fossils show that moths and butterflies have been on the planet for at least 200 million years. Scientists found fossilised butterfly scales the size of a speck of dust inside ancient rock from Germany. The find pushes back the date for the origins of the Lepidoptera, one of the most prized and studied insect groups. Researchers say they can learn more about the conservation of butterflies and moths by studying their early evolution. They used acid to dissolve ancient rocks, leaving behind small fragments, including "perfectly preserved" scales that covered the wings of early moths and butterflies. "We found the microscopic remains of these organisms in the form of these scales," said Dr Bas van de Schootbrugge from Utrecht University in the Netherlands. Intriguingly, they show that some of the moths and butterflies belonged to a group still alive today that have long straw-like tongues for sucking up nectar. "These finds push back the evolution of this group with proboscises - with a tongue - by about 70 million years," said Dr van de Schootbrugge. "Our finds show that the group that was supposed to co-evolve with flowers is actually much older." The Jurassic was a world dominated by gymnosperm plants, such as conifers, which produced sugary nectar to capture pollen from the air. The primitive insects may have fed on this nectar, before flowering plants came along around 130 million years ago.

Butterfly swarm shows up on Denver radar system
A colourful, shimmering spectacle detected by weather radar over the US state of Colorado has been identified as swarms of migrating butterflies. Scientists at the National Weather Service (NWS) first mistook the orange radar blob for birds and had asked the public to help identifying the species. They later established that the 70-mile wide (110km) mass was a kaleidoscope of Painted Lady butterflies. Forecasters say it is uncommon for flying insects to be detected by radar. "We hadn't seen a signature like that in a while," said NWS meteorologist Paul Schlatter, who first spotted the radar blip. "We detect migrating birds all the time, but they were flying north to south," he told CBS News, explaining that this direction of travel would be unusual for migratory birds for the time of year.

Painted lady butterflies’ migration may take them across the Sahara
Painted lady butterflies are found all over the world. New evidence shows that some may make an epic migration — across the Mediterranean and Sahara. Butterflies look so delicate as they flitter from flower to flower. And yet, they are capable of migrating incredibly long distances. The monarch, for example, migrates between Canada and Mexico, covering distances of up to 4,800 kilometers, riding a combination of columns of rising air, called thermals, and air currents to travel around 80 to 160 kilometers per day. No single monarch makes this entire journey, though. The round trip is done by a succession of as many as five generations of butterflies. But now scientists have found that there’s a species of butterfly that may rival the monarch’s migratory record — the painted lady (Vanessa cardui).
