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. Halobates - Wikipedia. Halobates or sea skaters are a genus with over 40 species of water striders.
While many are coastal, about five of these are able to survive and stand on the surface of the open ocean, a habitat containing very few insect species. They are predators, coastal species feeding mainly on fallen terrestrial insects while the oceanic species feed on plankton. The coastal species lay their eggs on rocks near the shore, the oceanic species attach their egg masses on floating objects such as cuttlebone, feathers and plastic waste. Species are found around the world, commonly near the equator. Most are tiny, the body length being about half a centimeter but with long legs of up to 2 centimeters.

It's real. 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. Put another way, 175 males could be lined up end to end in the space of an inch. 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.

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 enhanced risks were found from studies conducted in a laboratory, where bees were kept and various risk scenarios involving the spread of the parasite were tried out. The research was carried out at UC San Diego.

35 Amazing and Colourful Photographs of Dragonflies. Insect Covered in Dew. 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.
