Phidippus Californicus
''Phidippus californicus'' is a species of jumping spider. It is found in the southwestern United States (California, Arizona, New Mexico, Nevada, Texas, Utah) and northern Mexico ( Baja California peninsula, and Sonora). Habitat ''Phidippus californicus'' occurs in the sagebrush community of the Great Basin Desert. These large jumping spiders are found on bushes such as the sagebrush ('' Artemisia tridentata''), the rabbitbrush (''Chrysothamnus nauseosus''), and the Four-winged Saltbrush (''Atriplex canescens''). ''P. californicus'' prefers bushes that grow on slopes with thin, stony soils, and appears to avoid conifers and moist habitats (e.g., the proximity of irrigation ditches). In the same habitat, often on the same bush, two other ''Phidippus'' species are found: '' P. apacheanus'' and '' P. octopunctatus''.Gardner 1965 Description Females can reach 12 mm body length, males 7 to 11 mm. Both sexes have blue-green iridescent chelicerae, a black cephalothorax and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mazatlán
Mazatlán () is a city in the Mexican state of Sinaloa. The city serves as the municipal seat for the surrounding ''municipio'', known as the Mazatlán Municipality. It is located at on the Pacific coast, across from the southernmost tip of the Baja California Peninsula. ''Mazatlán'' is a Nahuatl word meaning "place of deer". The city was founded in 1531 by an army of Spaniards and indigenous people. By the mid-19th century, a large group of immigrants arrived from Germany. Over time, Mazatlán developed into a commercial seaport, importing equipment for the nearby gold and silver mines. It served as the capital of Sinaloa from 1859 to 1873. The German settlers also influenced the local music, banda, with some genres being an alteration of Bavarian folk music. The settlers also established the Pacifico Brewery on March 14, 1900. Mazatlán has a rich culture and art community. In addition to the Angela Peralta Theater, Mazatlán has many galleries and artist's studios. ...

Chelicerae
The chelicerae () are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders. Commonly referred to as "jaws", chelicerae may be shaped as either articulated fangs, or similarly to pincers. Some chelicerae, such as those found on nearly all spiders, are hollow and contain (or are connected to) venom glands, and are used to inject venom into prey or a perceived threat. In ''Pisaurina mira'', also known as the nursery web spider, the chelicerae are utilized to snatch the prey once it becomes within reach, facilitating the "sit-and-wait ambush predator" behavior. Both pseudoscorpions and harvestmen have structures on their chelicerae that are used for grooming (papillae in pseudoscorpions, cheliceral teeth in Opiliones). Types Chelicerae can be divided into three kinds: jackknife chelicerae, scissor chelicerae, and 3-segmented chelate chelicerae. Jackknife chelicerae The jackknife chelicera is subchelate (with ...

Spiders Of Mexico
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...

Fauna Of The Southwestern United States
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psyche (entomological Journal)
''Psyche'' is a scientific journal of entomology which was established in 1874 by the Cambridge Entomological Club as a "journal for the publication of biological contributions upon Arthropoda from any competent person". The name of the journal is derived from the Ancient Greek word for butterfly. The journal has been published since 1874 (with gaps from 1886 to 1887, 1995 to 1999, and 2000 to 2007). In 2007 the Club transferred the journal to the Hindawi Publishing Corporation, and it became an open-access journal in 2008, with articles distributed online under the Creative Commons Attribution License. Almost all back issues were scanned and are available online as PDF files. History Samuel Hubbard Scudder proposed to start an "Organ of the Cambridge Entomological Club" at its fourth meeting. When ''Psyche'' began publication, its first editor was B. P. Mann. Its articles concentrated on general anatomy, biological entomology, and to set up a Bibliographic Record of all writin ...

Musca Domestica
The housefly (''Musca domestica'') is a fly of the suborder Cyclorrhapha. It is believed to have evolved in the Cenozoic Era, possibly in the Middle East, and has spread all over the world as a commensal of humans. It is the most common fly species found in houses. Adults are gray to black, with four dark, longitudinal lines on the thorax, slightly hairy bodies, and a single pair of membranous wings. They have red eyes, set farther apart in the slightly larger female. The female housefly usually mates only once and stores the sperm for later use. She lays batches of about 100 eggs on decaying organic matter such as food waste, carrion, or feces. These soon hatch into legless white larvae, known as maggots. After two to five days of development, these metamorphose into reddish-brown pupae, about long. Adult flies normally live for two to four weeks, but can hibernate during the winter. The adults feed on a variety of liquid or semi-liquid substances, as well as solid materia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophila Melanogaster
''Drosophila melanogaster'' is a species of fly (the taxonomic order Diptera) in the family Drosophilidae. The species is often referred to as the fruit fly or lesser fruit fly, or less commonly the "vinegar fly" or "pomace fly". Starting with Charles W. Woodworth's 1901 proposal of the use of this species as a model organism, ''D. melanogaster'' continues to be widely used for biological research in genetics, physiology, microbial pathogenesis, and life history evolution. As of 2017, five Nobel Prizes have been awarded to drosophilists for their work using the insect. ''D. melanogaster'' is typically used in research owing to its rapid life cycle, relatively simple genetics with only four pairs of chromosomes, and large number of offspring per generation. It was originally an African species, with all non-African lineages having a common origin. Its geographic range includes all continents, including islands. ''D. melanogaster'' is a common pest in homes, restaurants, and othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mutillidae
The Mutillidae are a family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. Their common name velvet ant refers to their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold. Their bright colors serve as aposematic signals. They are known for their extremely painful stings, (the sting of the species ''Dasymutilla klugii'' rated a 3 on the Schmidt pain index and lasts up to 30 minutes), and has resulted in the common name "cow killer" or "cow ant" being applied to the species '' Dasymutilla occidentalis.'' However, mutillids are not aggressive and sting only in defense. In addition, the actual toxicity of their venom is much lower than that of honey bees or harvester ants. Unlike true ants, they are solitary, and lack complex social systems. Distribution Mutillidae can be found worldwide with about 230 genera or subgenera and around 8,000 species worldwide. Over 400 species occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimicry
In evolutionary biology, mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phidippus Clarus
Phidippus Clarus, also known as the Brilliant Jumping Spider, is a species of jumping spider (family Salticidae) found in old fields throughout eastern North America. It often waits upside down near the top of a plant, which may be useful for detecting prey, and then quickly jumps down before the prey can escape. The spider is one of 60 species in the genus ''Phidippus'', and one of about 5,000 in the Salticidae, a family that accounts for about 10% of all spider species. ''P. clarus'' is a predator, mostly consuming insects, other spiders, and other terrestrial arthropods. ''P. clarus'' is a relatively large salticid that is able to take prey up to the size of an adult earwig. In an experiment, ''P. clarus'' was offered as many fruit flies as it could eat in a four-hour session. On average individuals took 17 flies, with the maximum amount taken was a striking 41. When ''P. clarus'' males compete for females, the winners are those that produce the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
