Sexton Beetle
Burying beetles or sexton beetles, genus ''Nicrophorus'', are the best-known members of the family Silphidae (carrion beetles). Most of these beetles are black with red markings on the elytra (forewings). Burying beetles are true to their name—they bury the carcasses of small vertebrates such as birds and rodents as a food source for their larvae. They are unusual among insects in that both the male and female parents take care of the brood. They are carnivores. The genus name is sometimes spelled ''Necrophorus'' in older texts: this was an unjustified emendation by Carl Peter Thunberg (1789) of Fabricius's original name, and is not valid under the ICZN. The American burying beetle (''Nicrophorus americanus'') has been on the U.S. endangered species list since 1989. Reproduction Burying beetles have large club-like antennae equipped with chemoreceptors capable of detecting a dead animal from a long distance. After finding a carcass (most usually that of a small bird or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicrophorus Americanus
''Nicrophorus americanus'', also known as the American burying beetle or giant carrion beetle, is a critically endangered species of beetle endemic to North America. It belongs to the order Coleoptera and the family Silphidae. The carrion beetle in North America is carnivorous, feeds on carrion and requires carrion to breed. It is also a member of one of the few genera of beetle to exhibit parental care. The decline of the American burying beetle has been attributed to habitat loss, alteration, and degradation, and they now occur in less than 10% of their historic range. Description ''N. americanus'' adults are between 25 and 45 mm long and can be identified by their striking, distinctive coloring. The body is shiny black, and on each elytron (wing cover) are two scalloped, orange-red markings. Most distinctively, there is an orange-red marking on the pronotum, which distinguishes the species from all other North American '' Nicrophorus''. The front of the head has two ...

Antenna (biology)
Antennae ( antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments. While they are typically sensory organs, the exact nature of what they sense and how they sense it is not the same in all groups. Functions may variously include sensing touch, air motion, heat, vibration (sound), and especially smell or taste. Antennae are sometimes modified for other purposes, such as mating, brooding, swimming, and even anchoring the arthropod to a substrate. Larval arthropods have antennae that differ from those of the adult. Many crustaceans, for example, have free-swimming larvae that use their antennae for swimming. Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched ...

Honey Bee
A honey bee (also spelled honeybee) is a eusocial flying insect within the genus ''Apis'' of the bee clade, all native to Afro-Eurasia. After bees spread naturally throughout Africa and Eurasia, humans became responsible for the current cosmopolitan distribution of honey bees, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century). Honey bees are known for their construction of perennial colonial nests from wax, the large size of their colonies, and surplus production and storage of honey, distinguishing their hives as a prized foraging target of many animals, including honey badgers, bears and human hunter-gatherers. Only eight surviving species of honey bee are recognized, with a total of 43 subspecies, though historically 7 to 11 species are recognized. Honey bees represent only a small fraction of the roughly 20,000 known species of bees. The best known honey bee is the weste ...

Eusocial
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the so ...

Calliphoridae
The Calliphoridae (commonly known as blow flies, blow-flies, carrion flies, bluebottles, greenbottles, or cluster flies) are a family of insects in the order Diptera, with almost 1,900 known species. The maggot larvae, often used as fishing bait, are known as gentles. The family is known to be polyphyletic, but much remains disputed regarding proper treatment of the constituent taxa, some of which are occasionally accorded family status (e.g., Bengaliidae and Helicoboscidae). The name blowfly comes from an older English term for meat that had eggs laid on it, which was said to be flyblown. The first known association of the term "blow" with flies appears in the plays of William Shakespeare: '' Love's Labour's Lost'', '' The Tempest'', and '' Antony and Cleopatra''. Description Characteristics Calliphoridae adults are commonly shiny with metallic colouring, often with blue, green, or black thoraces and abdomens. Antennae are three-segmented and aristate. The aristae are pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infanticide (zoology)
In animals, infanticide involves the intentional killing of young offspring by a mature animal of the same species. Animal infanticide is studied in zoology, specifically in the field of ethology. Ovicide is the analogous destruction of eggs. The practice has been observed in many species throughout the animal kingdom, especially primates ( primate infanticide) but including microscopic rotifers, insects, fish, amphibians, birds and mammals. Infanticide can be practiced by both males and females. Infanticide caused by sexual conflict has the general theme of the killer (often male) becoming the new sexual partner of the victim's parent, which would otherwise be unavailable. This represents a gain in fitness by the killer, and a loss in fitness by the parents of the offspring killed. This is a type of evolutionary struggle between the two sexes, in which the victim sex may have counter-adaptations that reduce the success of this practice. It may also occur for other reasons, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ross Piper
Ross Piper is a British zoologist, entomologist, and explorer. Biography Piper's fascination by animals began at a young age through early encounters with a violet ground beetle and the caterpillar of an elephant hawk moth. This early interest led to a degree in zoology from Bangor University and a PhD in insect ecology from the University of Leeds. Piper has travelled widely in Europe, the Americas, Africa and Southeast Asia, searching for interesting and elusive beasts. Although his focus is arthropods, the sheer diversity of animal forms and lifestyles is a continual source of fascination. In 2015 he was awarded the Alumnus of the Year award by Bangor University and has since become a member of their alumni advisory board. He is also a student mentor for the University of Leeds and a Fellow of the Royal Geographical Society. He is currently a visiting research fellow at the University of Leeds and a visiting fellow at the University of Essex. His current projects include aut ...

Progressive Provisioning
Progressive provisioning is a term used in entomology to refer to a form of parental behavior in which an adult (most commonly a hymenopteran such as a bee or wasp) feeds its larvae directly after they have hatched, feeding each larva repeatedly until it has completed development. The food is typically in the form of masticated or immobilized prey items (in predatory wasps), or regurgitated nectar mixed with pollen (in bees); only rarely are other sorts of food resources used (such as glandular secretions, or carrion). While this sort of direct and repetitive feeding of offspring is extremely common in groups such as birds and mammals, it is far less common among insects, with the exception of eusocial insects (one of the defining features of eusociality is cooperative brood care). Accordingly, progressive provisioning is universal among ants, and widespread among the social bees and wasps. Certain nonsocial wasps also rear their young with this type of feeding. Young termites (an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regurgitation (digestion)
Regurgitation is the expulsion of material from the pharynx, or esophagus, usually characterized by the presence of undigested food or blood. Regurgitation is used by a number of species to feed their young. This is typically in circumstances where the young are at a fixed location and a parent must forage or hunt for food, especially under circumstances where the carriage of small prey would be subject to robbing by other predators or the whole prey is larger than can be carried to a den or nest. Some bird species also occasionally regurgitate pellets of indigestible matter such as bones and feathers. It is in most animals a normal and voluntary process unlike the complex vomiting reflex in response to toxins. Humans In humans it can be voluntary or involuntary, the latter being due to a small number of disorders. Regurgitation of a person's meals following ingestion is known as rumination syndrome, an uncommon and often misdiagnosed motility disorder that affects eating. It m ...

Begging Behavior In Animals
Begging in animals is when an animal solicits being given resources by another animal. This is usually a young animal soliciting food from their parents, brood hosts or other adults. However, the resource is sometimes non-food related or may be solicited by adult animals. Begging behavior is most widely studied in birds, however, mammals, amphibians, and invertebrates perform begging displays. Generally in food solicitation, begging behavior is instinctive, although in some instances it is learned (e.g. pet cats and dogs). While the ultimate causation for begging is an increase in the animal's individual fitness, several theories have been proposed for how food begging evolved proximate causes including scramble competition, honest signalling of need, and cooperative begging by siblings. Various types of information such as nutritional status or immunocompetence can be transmitted with auditory and visual begging signals and the behavior can be modulated by several factors such ...
