Ezra Townsend Cresson
Ezra Townsend Cresson, also Ezra Townsend senior (18 June 1838, in Byberry – 19 April 1926, in Swarthmore) was an American entomologist who specialised in the Hymenoptera order of insects. He wrote ''Synopsis of the families and genera of the Hymenoptera of America, north of Mexico'' Philadelphia: Paul C. Stockhausen, Entomological printer (1887) and many other works. His son Ezra Townsend, Jr. (1876–1948) was also an entomologist but a specialist in Diptera. Cresson also documented many new species including ''Nomada texana ''Nomada texana'' is a species of bee native to the southern and western United States and other parts of North America (including Mexico Mexico (Spanish language, Spanish: México), officially the United Mexican States, is a List of sover ...''.

Halictidae
Halictidae is the second-largest family of bees (clade Anthophila) with nearly 4,500 species. Halictid species are an extremely diverse group that can vary greatly in appearance. These bees occur all over the world and are found on every continent except Antarctica. Usually dark-colored (frequently brown or black) and often metallic, halictids are found in various sizes, colors and patterns. Several species are all or partly green and a few are red, purple, or blue. A number of them have yellow markings, especially the males, which commonly have yellow faces, a pattern widespread among the various families of bees. The family is one of many with short tongues and is best distinguished by the arcuate (strongly curved) basal vein found on the wing. Females in this family tend to be larger than the males. They are commonly referred to as "sweat bees" (especially the smaller species), as they are often attracted to perspiration. Ecology Most halictids nest in the ground, often in ha ...

Sweat Bee, Honey-bellied Agapostemon (Halictidae, Agapostemon Melliventris (Cresson) (35650960681)
Perspiration, also known as sweating, is the production of fluids secreted by the sweat glands in the skin of mammals. Two types of sweat glands can be found in humans: eccrine glands and apocrine glands. The eccrine sweat glands are distributed over much of the body and are responsible for secreting the watery, brackish sweat most often triggered by excessive body temperature. The apocrine sweat glands are restricted to the armpits and a few other areas of the body and produce an odorless, oily, opaque secretion which then gains its characteristic odor from bacterial decomposition. In humans, sweating is primarily a means of thermoregulation, which is achieved by the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2–4 liters per hour or 10–14 liters per day (10–15 g/min·m2), but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence, in hot wea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agapostemon
The genus ''Agapostemon'' (literally "stamen loving") is a common group of Western Hemisphere sweat bees, most of which are known as ''metallic green sweat bees'' for their color. They are members of the family of bees known as Halictidae. Like other sweat bees, they are attracted to human sweat, and they use the salt from the sweat for nutrition. They are generally green or blue, especially the head and thorax. Sometimes the abdomen in females is green or blue although it may be striped, and most males have the yellow-striped abdomen on a black or metallic background. They superficially resemble various members of another tribe, Augochlorini, which are also typically metallic green. Nesting All species of ''Agapostemon'' nest in the ground, sometimes in dense aggregations. Some species are communal such as ''A. virescens''. In this and other communal species, multiple females share the same nest entrance, but beneath the common entrance burrow, construct their own portion of t ...

Insects Described In 1874
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
