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.

First U.S. Bumblebee Officially Listed as Endangered. It’s official: For the first time in the United States, a bumblebee species has been declared endangered.

First U.S. Bumblebee Officially Listed as Endangered

The rusty patched bumblebee (Bombus affinis), once a common sight, is “now balancing precariously on the brink of extinction,” according to the U.S. Fish and Wildlife Service. Once thriving in 28 states and the District of Columbia, but over the past two decades, the bee’s population has plummeted nearly 90 percent. There are more than 3,000 bee species in the United States, and about 40 belong to the genus Bombus—the bumblebees.

Halobates. 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.[1] Species are found around the world, commonly near the equator.[2] Most are tiny, the body length being about half a centimeter but with long legs of up to 2 centimeters.

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. 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.

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 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.
