Histiostomatidae
Histiostomatidae is a family of mites in the clade Astigmata. Description These mites are characterized by a very small size (about 600–900 µm in length) and a close association to arthropods, mainly insects. A morphologically specialized instar, the deutonymph (earlier "hypopus"), is adapted to attach to arthropods for phoretic transport from one habitat to another. The mites use various insect groups as phoretic carriers such as beetles, flies and Hymenoptera (ants, bees and wasps). In all species, the digitus mobilis of the chelicera is reduced to small rests, and the distal pedipalp article is connected to a more or less complex membranous structure. These mouthpart modifications form an organ to feed on bacteria. Habitats colonized by these mites include animal dung, compost, water-filled tree hollows and the fluids of '' Nepenthes'' and ''Sarracenia ''Sarracenia'' ( or ) is a genus comprising 8 to 11 species of North American pitcher plants, commonly ...

Astigmata
Astigmatina is a clade of mites in the superorder Acariformes. Astigmata has been ranked as an order or suborder in the past, but was lowered to the unranked clade Astigmatina of the clade Desmonomatides (synonym Desmonomata) in the order Sarcoptiformes. Astigmatina is now made up of the two groups Acaridia and Psoroptidia, which have been suborders of the order Astigmata in the past. Astigmatina contains about 10 superfamilies and 76 families under Acaridia and Psoroptidia. Astigmatina belongs to the Sarcoptiformes, which contains the "biting" Acariformes. Many species are parasites of vertebrates. Most notorious among these are the Psoroptidia, which contain such notable taxa as feather mites and ''Sarcoptes scabiei''. Description Astigmatan mites are usually soft-bodied and white to brownish in colour (rarely tan and well-sclerotised), and range from 0.15 to 2.00 mm in length. They lack stigmatal openings (thus the name of the clade), peritremes or prodorsal Sensillum, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pedipalp
Pedipalps (commonly shortened to palps or palpi) are the second pair of appendages of chelicerates – a group of arthropods including spiders, scorpions, horseshoe crabs, and sea spiders. The pedipalps are lateral to the chelicerae ("jaws") and anterior to the first pair of walking legs. Overview Pedipalps are composed of six segments or articles: the coxa, the trochanter, the femur, the short patella, the tibia, and the tarsus. In spiders, the coxae frequently have extensions called maxillae or gnathobases, which function as mouth parts with or without some contribution from the coxae of the anterior legs. The limbs themselves may be simple tactile organs outwardly resembling the legs, as in spiders, or chelate weapons ( pincers) of great size, as in scorpions. The pedipalps of Solifugae are covered in setae, but have not been studied in detail. Comparative studies of pedipalpal morphology may suggest that leg-like pedipalps are primitive in arachnids. At present, the only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas A&M University
Texas A&M University (Texas A&M, A&M, or TAMU) is a public, land-grant, research university in College Station, Texas. It was founded in 1876 and became the flagship institution of the Texas A&M University System in 1948. As of late 2021, Texas A&M has the largest student body in the United States, and is the only university in Texas to hold simultaneous designations as a land, sea, and space grant institution. In 2001, it was inducted into the Association of American Universities. The university's students, alumni, and sports teams are known as Aggies, and its athletes compete in eighteen varsity sports as a member of the Southeastern Conference. The university was the first public higher-education institution in Texas; it opened for classes on October 4, 1876, as the Agricultural and Mechanical College of Texas (A.M.C.) under the provisions of the 1862 Morrill Land-Grant Act. In the following decades, the college grew in size and scope, expanding to its largest enrol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sarracenia
''Sarracenia'' ( or ) is a genus comprising 8 to 11 species of North American pitcher plants, commonly called trumpet pitchers. The genus belongs to the family Sarraceniaceae, which also contain the closely allied genera '' Darlingtonia'' and ''Heliamphora''. ''Sarracenia'' is a genus of carnivorous plants indigenous to the eastern seaboard of the United States, Texas, the Great Lakes area and southeastern Canada, with most species occurring only in the south-east United States (only '' S. purpurea'' occurs in cold-temperate regions). The plant's leaves have evolved into a funnel or pitcher shape in order to trap insects. The plant attracts its insect prey with secretions from extrafloral nectaries on the lip of the pitcher leaves, as well as a combination of the leaves' color and scent. Slippery footing at the pitcher's rim, causes insects to fall inside, where they die and are digested by the plant with proteases and other enzymes. Description ''Sarracenia'' are herba ...
