Chalybion Californicum
''Chalybion californicum'', the common blue mud dauber of North America, is a metallic blue species of mud dauber wasp first described by Henri Louis Frédéric de Saussure in 1867. It is not normally aggressive towards humans. It is similar in shape and colour to the steel-blue cricket hunter (''Chlorion aerarium''). Like other types of wasps, males do not have an ovipositor, and therefore cannot sting. It is ranged from northern Mexico to southern Canada, including most of the United States. It has also been introduced to regions including Hawaii, Bermuda, Croatia and other European countries. Behavior Females can build their own nests, but often refurbish nests abandoned by other wasps and bees, particularly those of '' Sceliphron caementarium'''', removing any spiders captured by ''S. caementarium'' and the larva, replacing it with an egg of its own and freshly caught spiders. They go through multiple generations in a year. Interaction with other species This species is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henri Louis Frédéric De Saussure
Henri Louis Frédéric de Saussure (; ; 27 November 1829 – 20 February 1905) was a Swiss mineralogist and entomologist specialising in studies of Hymenoptera and Orthopteroid insects. He also was a prolific taxonomist. Biography Saussure's elementary education was at Alphonse Briquet's then, as an adolescent, at the Hofwyl school run by Philipp Emanuel von Fellenberg. At the University of Geneva he was taught by François Jules Pictet de la Rive, who introduced him to entomology. After several years of study in Paris he received the degree of licentiate of the Faculty of Paris and obtained the degree of Doctor from the University of Giessen. He worked mainly on Hymenoptera and Orthoptera. His first paper, in 1852, was on solitary wasps. In 1854 he traveled to the West Indies, then to Mexico and the United States of America. There he met Louis Agassiz. He returned to Switzerland in 1856 with collections of American insects, myriapods, crustaceans, birds and ma ...

Iowa State University
Iowa State University of Science and Technology (Iowa State University, Iowa State, or ISU) is a public land-grant research university in Ames, Iowa. Founded in 1858 as the Iowa Agricultural College and Model Farm, Iowa State became one of the nation's first designated land-grant institution when the Iowa Legislature accepted the provisions of the 1862 Morrill Act on September 11, 1862, making Iowa the first state in the nation to do so. On July 4, 1959, the college was officially renamed Iowa State University of Science and Technology. Iowa State is classified among "R1: Doctoral Universities – Very high research activity". The university is home to the Ames Laboratory, one of ten national U.S. Department of Energy Office of Science research laboratories, the Biorenewables Research Laboratory, the Plant Sciences Institute, and various other research institutes. Iowa State is the second-largest university in the State of Iowa by undergraduate enrollment. The university's ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of North America
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sphecidae
The Sphecidae are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps. The name Sphecidae was formerly given to a much larger grouping of wasps. This was found to be paraphyletic, so most of the old subfamilies have been moved to the Crabronidae. Biology The biology of the Sphecidae, even under the restricted definition, is still fairly diverse; some sceliphrines even display rudimentary forms of sociality, and some sphecines rear multiple larvae in a single large brood cell. Many nest in pre-existing cavities, or dig simple burrows in the soil, but some species construct free-standing nests of mud and even (in one genus) resin. All are predatory and parasitoidal, but the type of prey ranges from spiders to various dictyopterans, orthopteroids and larvae of either Lepidoptera or other Hymenoptera; the vast majority practice mass provisioning, providing all the prey items prior to laying the egg.

Latrodectus Mactans
''Latrodectus mactans'', known as southern black widow or simply black widow, and the shoe-button spider, is a venomous species of spider in the genus ''Latrodectus''. The females are well known for their distinctive black and red coloring and for the fact that they will occasionally eat their mates after reproduction. The species is native to North America. The venom can cause pain and other symptoms, but is rarely fatal to healthy humans. Taxonomy ''Latrodectus mactans'' was first described by Johan Christian Fabricius in 1775, placing it in the genus '' Aranea''. It was transferred to the genus ''Latrodectus'' in 1837 by Charles Walckenaer and is currently placed in the family Theridiidae of the order Araneae. The species is closely related to ''Latrodectus hesperus'' (western black widow) and ''Latrodectus variolus'' (northern black widow). Members of the three species are often confused with the genus '' Steatoda'', the false widows. Prior to 1970, when the current taxonomi ...

Zizia Aurea
''Zizia aurea'' (golden alexanders, golden zizia) is a flowering herbaceous perennial plant of the carrot family Apiaceae. It is native to eastern Canada and the United States, from the eastern Great Plains to the Atlantic Coast. It is named for Johann Baptist Ziz, a German botanist. Description ''Zizia aurea'' grows to tall but can sometimes grow taller. The leaves are long and wide. They are attached to the stems alternately. Each leaf is compound and odd-pinnate, with leaflets that are normally lanceolate or ovate with serrated edges. The root system consists of a dense cluster of coarse fibrous roots. It blooms from May to June. Its flowers are yellow and grow in a flat-topped umbel at the top of the plant. Each flower is only long and has five sepals, five petals, and five stamens. Each flower produces a single long, oblong fruit (schizocarp) containing two seeds. In the fall both the leaves and the fruit turn purple. Distribution and habitat Golden Alexanders is ...

Insect Pollination
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar; they may also have an attractive scent which in some cases mimics insect pheromones. Insect pollinators such as bees have adaptations for their role, such as lapping or sucking mouthparts to take in nectar, and in some species also pollen baskets on their hind legs. This required the coevolution of insects and flowering plants in the development of pollination behaviour by the insects and pollination mechanisms by the flowers, benefiting both groups. Coevolution History The early spermatophytes (seed plants) were largely dependent on the wind to carry their pollen from one plant to another. Prior to the appearance of flowering plants some gymnosper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Latrodectus
''Latrodectus'' is a broadly distributed genus of spiders with several species that are commonly known as the true widows. This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders. However, the diversity of species is much greater. A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows" (southern black widow ''Latrodectus mactans'', western black widow ''Latrodectus hesperus'', and northern black widow ''Latrodectus variolus''). Besides these, North America also has the red widow ''Latrodectus bishopi'' and the brown widow ''Latrodectus geometricus'', which, in addition to North America, has a much wider geographic distribution. Elsewhere, others include the European black widow (''Latrodectus tredecimguttatus''), the Australian redback black widow (''Latrodectus hasseltii'') and the closely related New Zealand katipō (''Latrodectus katipo''), several differ ...
