Stictia Carolina
The horse guard wasp (''Stictia carolina'') is a type of sand wasp (Bembicini) from the eastern United States which preys primarily upon Horse-flies (Tabanidae). It is a large, colorful, fast-flying wasp, one of 28 species in the genus ''Stictia'' (which occur throughout North and South America), all of which have similar biology. Biology A female wasp of this species may take anywhere from 30 to 60 flies as food to provision each one of her nests; she makes a new nest for every egg she lays. Nests are simple burrows some 15 cm deep, with a single enlarged chamber at the bottom. An egg is laid in the empty chamber, and the female wasp brings back paralyzed flies and sometimes silver-spotted skipper larvae until the chamber is full (mass provisioning), at which point she closes the nest and begins another. Numerous females often excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations. Nearly all the prey ar ...

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoology, zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect Biological classification, classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium (school), gymnasium at Altona, Hamburg, Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala University, Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bembicini
The Bembicini, or sand wasps, are a large tribe of crabronid wasps, comprising 20 genera. Bembicines are predators on various groups of insects. The type of prey captured tends to be rather consistent within each genus, with flies ( Diptera) being the most common type of prey taken. Nests are typically short, simple burrows, with a single enlarged chamber at the bottom which is stocked with freshly paralysed prey items for the developing wasp larva; the egg may sometimes be laid before the chamber is completely stocked. It is common for numerous females to excavate nests within a small area where the soil is suitable, creating large and sometimes very dense nesting aggregations, which tend to attract various species of parasitic flies and wasps, many of which are cleptoparasites; in some cases, the sand wasps prey on their own parasite Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the ...

Horse-fly
Horse-flies or horseflies are true flies in the family Tabanidae in the insect order Diptera. They are often large and agile in flight, and only the female horseflies bite animals, including humans, to obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night. They are found all over the world except for some islands and the polar regions (Hawaii, Greenland, Iceland). Both horse-flies and botflies (Oestridae) are sometimes referred to as gadflies. Adult horse-flies feed on nectar and plant exudates; the males have weak mouthparts and only the females bite animals to obtain enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a spongelike part used to lap up the blood that flows from the wound. The larvae are predaceous and grow in semiaquatic habitats. Female horse-flies can transfer blood-borne diseases from one animal to anoth ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe.

Burrow
An Eastern chipmunk at the entrance of its burrow A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions. Many animal species are known to form burrows. These species range from small invertebrates, such as the '' Corophium arenarium'', to very large vertebrate species such as the polar bear. Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of meters in total length; an example of the latter level of complexity, a well-developed burrow, would be a rabbit warren. Vertebrate burrows A large variety of vertebrates construct or use burrows in ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paralysis
Paralysis (also known as plegia) is a loss of motor function in one or more muscles. Paralysis can also be accompanied by a loss of feeling (sensory loss) in the affected area if there is sensory damage. In the United States, roughly 1 in 50 people have been diagnosed with some form of permanent or transient paralysis. The word "paralysis" derives from the Greek παράλυσις, meaning "disabling of the nerves" from παρά (''para'') meaning "beside, by" and λύσις (''lysis'') meaning "making loose". A paralysis accompanied by involuntary tremors is usually called " palsy". Causes Paralysis is most often caused by damage in the nervous system, especially the spinal cord. Other major causes are stroke, trauma with nerve injury, poliomyelitis, cerebral palsy, peripheral neuropathy, Parkinson's disease, ALS, botulism, spina bifida, multiple sclerosis, and Guillain–Barré syndrome. Temporary paralysis occurs during REM sleep, and dysregulation of this syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epargyreus Clarus
''Epargyreus clarus'', the silver-spotted skipper, is a butterfly of the family Hesperiidae. It is claimed to be the most recognized skipper in North America. occurs in fields, gardens, and at forest edges and ranges from southern Canada throughout most of the United States to northern Mexico, but is absent in the Great Basin and western Texas. larvae create and reside in unique shelters stuck together with silk, which do not protect them from predators. Natural predators of the species include paper wasp foragers, sphecid wasp and ''Crematogaster opuntiae'' ants. The species is also considered to be a perching species, meaning that adult males compete for territory to attract females. Although is considered to be a pest of a few crop plants such as beans, its pest activity is not serious enough to warrant initiating major control measures. Geographic range ''Epargyreus clarus'' has a wide distribution throughout North America: it ranges from southern Canada through ...

Mass Provisioning
Mass provisioning is a form of parental investment in which an adult insect, most commonly a hymenopteran such as a bee or wasp, stocks all the food for each of her offspring in a small chamber (a "cell") before she lays the egg. This behavior is common in both solitary and eusocial bees, though essentially absent in eusocial wasps. Diversity In bees, stored provisions typically consist of masses of mixed pollen and nectar, though a few species store floral oils. In a few cases, such as stingless bees and some Halictidae, sweat bees, the number of cells in a single nest can number in the hundreds to thousands, but more typically a nest contains either a single cell, or a small number (fewer than 10). In predatory wasps, the food is typically in the form of paralyzed or dead prey items; after digging the nest they quickly catch one or a few prey animals, bring them to the nest and lay eggs on them, seal the nest and leave. Some wasp lineages (e.g. Crabronidae) show variation, wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bot Fly
Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. '' Dermatobia hominis'' is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans. General A botfly, also written bot fly, bott fly or bot-fly in various combinations, is any fly in the family Oestridae. Their life cycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. Largely according to species, they also are known variously as warble flies, heel flies, and gadflies. The larvae of some species grow in the flesh of their hosts, while others grow within the hosts' alimentary tracts. The word "bot" in this sense means a maggot. A warble is a skin lump or callus such as might be caused by an ill-fitting harness, or by the presence of a war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
