Insects & Arachnids

Facebook Twitter

INSECTS have six legs, antennae, and are segmented into 3 body parts. They are by far the most diverse animal group on the planet, making up 90% of all animals that have ever lived.

Though more ancient, ARACHNIDS are a much smaller group that only includes Spiders, Scorpions, Ticks, Mites, Camel Spiders, and Daddy Long-legs. Arachnids have eight legs and are segmented into 2 body parts.

Six-Legged Giant Finds Secret Hideaway, Hides For 80 Years. Honey bees trained to detect cancer. Dutch Design Week 2013: Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees ( + slideshow).

The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer. "Trained bees only rush into the smaller chamber if they can detect the odour on the patient's breath that they have been trained to target," explained Soares, who presented her Bee's project at Dutch Design Week in Eindhoven last month. Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range. Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer. Revealing Metamorphosis. Before turning into a butterfly, a caterpillar wraps itself in a chrysalis.

But what goes on within that casing during the weeks it takes the insect to transform is still a bit of a mystery to science. Now researchers have used high-resolution computer tomography (CT) scans to track the development of the painted lady butterfly (Vanessa cardui), mapping changes in a living individual as it metamorphoses. They published their results—along with several remarkably detailed images—today (May 14) in Journal of the Royal Society Interface. “The crucial thing in this case is that they examined live material,” said Rolf Beutel, a professor of entomology at Friedrich Schiller University of Jena in Germany, who was not involved in the study. Tinkerbella nana. The family Mymaridae includes more than 1,400 species of diminutive insects called fairyflies.

They are not flies at all, but tiny wasps that deposit their eggs inside the eggs of other insects. Most of these parasitoids are found in tropical latitudes and the southern hemisphere, where they attack unborn offspring of true bugs, beetles, flies, barkflies and dragonflies. The family includes the smallest of all known insects, Dicopomorpha echmepterygis, from Central America, whose males are a mere 139μm That is smaller than quite a few single-celled protists. Fight to the death. New praying mantis species discovered. Nineteen new species of a tree-living praying mantis family have been discovered, tripling the group’s diversity at a stroke.

The bark mantises (Liturgusa Saussure) from Central and South America were found in tropical forests and among specimens kept in museums. Many of the newly described species are known only from a few specimens collected before 1950 from locations now heavily impacted by agriculture or urban development. “Based on this study, we can predict that mantis groups with similar habitat specialisation in Africa, Asia and Australia will also be far more diverse than what is currently known,” said Dr Gavin Svenson, curator of invertebrate zoology at the Cleveland Museum of Natural History in the US. “Many of these groups have never been studied other than by the scientists that originally described some of the species, which in some cases is more than 100 years ago.

Tailess Whip Scorpion. The Incredible Praying Mantis. Mantodea (or mantises) is an order of insects that contains approximately 2,200 species in 15 families worldwide in temperate and tropical habitats.

The Incredible Praying Mantis

A colloquial name for the order is “praying mantises”, because of the typical “prayer-like” stance, although the term is often misspelled as “preying mantis” since mantises are predatory. Bush-crickets have the world's biggest testicles (relatively speaking) Egyptian Giant Solpugids (Camel Spider) Camel spiders became an Internet sensation during the Iraq war of 2003, when rumors of their bloodthirsty nature began to circulate online.

Many tales were accompanied with photos purporting to show spiders half the size of a human. For many years, Middle Eastern rumors have painted camel spiders as large, venomous predators, as fast as a running human, with a voracious appetite for large mammals. 20 Lovely Macro Photographs By Magdalena Wasiczek  Who's Your Daddy? Moth camouflaged against a page. Parasites Are Wiping Out Entire Honeybee Colonies. Bees around the world are at risk from a number of threats including habitat loss and the effect of pesticides, plus bacterial disease like American foulbrood.

Parasites Are Wiping Out Entire Honeybee Colonies.

Bee colonies are also at risk from mites (especially Varroa mite parasite) and parasites. Although parasites have long been associated with “colony collapse disorder”, where entire hives are wiped out, it is only recently that the magnitude of the threat has been fully realised. The parasite concerned is a microsporidian called Nosema ceranae, which can harm adult bees and their larvae. It causes adult bees to die early, and kills the larvae before they can transform into bees. It is spread easily via airborne spores. The parasite poses a particular threat to honeybees found in Europe and across Asia. The Honeybee’s Final Sting. Jun 16, 2012.

Whip Scorpion. We've seen the elegant Scorpion with their often rather dainty pincers, now let's see their relatives, the chunky Whip Scorpions with their own brutal, barbarous claws.

Whip Scorpion

Whip Scorpions, also known oddly as Vinegaroons, are indeed arachnids with thick, hefty bodies. Most of them are 3 cm (1.2 in) long or a bit under, but the biggest ones can reach 8.5 cm (3.3 in). They have their 8 legs but, just like our very own Camel Spider, they only use 6 of them to walk. The first pair are longer and thinner than the rest and used as antennae. Weird how they looked at those Camel Spiders and thought "good idea", yet the most famous arachnids - spiders and scorpions - haven't felt the need.They get their name from looking a bit like a scorpion.

The Assassin Bug. With a name like the assassin bug, you can be sure this is one tough insect. As it turns out though, the assassin bug doesn’t just kill and eat its victims—it also wears their exoskeletons as part of its suit of armor. In a way, this Malaysian bug is probably the closest thing the insect world has to a deranged serial killer. After it’s made a kill, the assassin bug—which calls Malaysia home—injects its victim with a special enzyme that dissolves and softens its guts so they can be easily sucked out. And once all that’s left is the insect’s empty shell, the assassin bug attaches those exoskeletons to its back using a sticky secretion, piling them high to create a thick layer of protective armor that also serves to confuse its enemies. It might seem like a ridiculous stunt, but imagine you were fighting a war and saw a soldier coming at you covered in dead bodies. Source Most Popular Posts This Week.

There are tiny bugs closely related to spiders living in the pores of your face. They have long been considered mere passengers, doing no harm beyond upsetting the squeamish. But they may be causing an ancient skin disease that is estimated to affect between 5 and 20 per cent of people worldwide, and 16 million in the US alone. People aged between 30 and 60, especially women, sometimes develop rosacea: red inflamed skin, with swelling, roughness and fine, visible blood vessels, usually in the central zone of the face.

Severe cases can resemble acne, irritate the eyes and lead to the bulbous red nose seen in caricatures of the elderly. The disease affects all races but is known as the "curse of the Celts" as it is thought to especially affect people with very fair skin, although it may simply be more visible on their skin.
