Orchid Mantis: The Predator That Lures Prey By Mimicking Flowers

Praying or preying

The orchid mantis (hymenopus coronatus) is famous for its remarkable similarity to the orchid
flower, but researchers from Macquarie University have now discovered that its’ unique form of deception not only attracts its prey by resembling a blossom, but is in fact even more attractive to pollinators than the real flower.
Since its discovery in South East Asia more than a century ago, the rarity and elusive nature of the orchid mantis has made it difficult for scientists to understand why and how it has evolved this bizarre appearance.
Researchers James O’Hanlon and Marie Herberstein from Macquarie University, along with Gregory Holwell from the University of Auckland mounted an expedition to Malaysia to study the orchid mantis. They observed that the body of the orchid mantis was attractive to flying insects, demonstrating how their flower-like appearance has evolved to lure in unsuspecting pollinators searching for nectar in flowers.
“What really surprised us was the fact that the orchid mantises were even more successful at attracting pollinators than real flowers,” said O’Hanlon.
“Their bright floral colours and petal shaped legs create a tantalizing lure for insects. So it seems that orchid mantises not only look like flowers but also beat flowers at their own game.
“After more than a century of conjecture we provide the first experimental evidence of pollinator deception in the orchid mantis and the first description of a unique predatory strategy that has not been documented in any other animal species.”
Their findings have been published in the Chicago Journals for The American Society of Naturalists.

'Nymph' insect with troll-like iridescent tuft of 'hair' discovered in South America

Suriname, to be exact:

The 7mm-long creature is golden  and its elongated body is covered in orange dots and stripes. It has hair-like feelers sticking out of its rear which resemble the fuzzy hair of the colourful Troll Dolls, a popular toy in the 1990s. 

The 7mm-wide insect, pictured, was discovered after researchers from the University of Harvard trekked for three weeks to explore the untouched rainforest of southeast Suriname. The unnamed creature is covered in orange dots and stripes. Its feelers are made of wax that protrude from its rear end

Researchers believe the bug is an immature insect called a nymph, possibly fitting into one of four nymph families: Dictyopharidae, Nogodinidae, Lophopidae, and Tropiduchidae.

A nymph is an immature insect. In insects that undergo a gradual metamorphosis, the stage of the life cycle that hatches from the egg is called the nymph. These insects do not pupate like a butterfly.

Often, the nymph looks like a smaller, wingless version of the adult. The nymph may molt several times to reach adulthood.

Insects that undergo simple or gradual metamorphosis, and have a nymph stage, include grasshoppers and crickets, cockroaches, termites and dragonflies.

Dr. Leeanne Alonso, the expedition's leader, said: 'I have conducted expeditions all over the world, but never have I seen such beautiful, pristine forests so untouched by humans.

'Southern Suriname is one of the last places on earth where there is a large expanse of pristine tropical forest.

Woman bitten by recluse spider, ear rots, doctors recreate it with rib cartilage

From Holland:

One woman's Italian vacation took a turn for the worse when she woke up with pain in her ear one night. She had no way of knowing then that she'd just been bitten by a Mediterranean recluse spider, and that a chunk of her ear would soon be liquefied by the spider's venom. But that's exactly what happened, according to a recent report of her case.
The 22-year-old woman soon sought treatment for her pain in an Italian hospital, where doctors prescribed an antihistamine. But the swelling in her face and pain in her ear didn't get any better. Once she was back home in the Netherlands, the ear got worse, and portions of it turned black — a clear sign that the skin and cartilage cells were dead.
The dead tissue made it clear to doctors that the woman had been bitten by a Mediterranean recluse, a spider whose bite is known to destroy skin and underlying fat, causing "sunken-in" scars or "a disfigured ear, if you are very unlucky," said Dr. Marieke van Wijk, a plastic surgeon in the Netherlands involved in the woman's treatment. In this case, van Wijk and her colleagues removed the dead tissue, and recreated it using cartilage from the woman's ribs.
Recluse spiders rarely bite people, and when they do, the bites don't usually inflict serious damage or large scars. Most bites occur when people roll over onto a spider while asleep, or when they put their foot into a shoe in which a recluse is found. It's difficult to diagnose a brown-recluse-spider bite, and many suspected bites actually come from stinging insects, or are caused by other things, such as bacterial infections.
