Rabdophaga Salicisbrassicoides
''Rabdophaga salicisbrassicoides'', known generally as the willow rosette gall midge or willow cabbage gall midge, is a species of gall midges in the family Cecidomyiidae. Their galls and larvae thrive in association with the mutualistic relationship between '' Formica neoclara'' and '' Chaitophorus'' aphids found on their host species ''Salix exigua ''Salix exigua'' (sandbar willow, narrowleaf willow, or coyote willow; syn. ''S. argophylla, S. hindsiana, S. interior, S. linearifolia, S. luteosericea, S. malacophylla, S. nevadensis,'' and '' S. parishiana'') is a species of willow native to m ...''.

Alpheus Spring Packard
Alpheus Spring Packard Jr. LL.D. (February 19, 1839 – February 14, 1905) was an American entomologist and palaeontologist. He described over 500 new animal species – especially butterflies and moths – and was one of the founders of ''The American Naturalist''.Cockerell (1920) Early life He was the son of Alpheus Spring Packard Sr. (1798–1884) and the brother of William Alfred Packard. He was born in Brunswick, Maine, and was Professor of Zoology and Geology at Brown University in Providence, Rhode Island, from 1878 until his death. He was a vocal proponent of Neo-Lamarckism during the eclipse of Darwinism.Sorenson (1995) Career & Works His chief work was the classification and anatomy of arthropods, and contributions to economic entomology, zoogeography, and the phylogeny and metamorphoses of insects. Packard was appointed to the United States Entomological Commission in 1877 where he served with Charles Valentine Riley and Cyrus Thomas.Mallis (1971) He wrote school text ...

Cecidomyiidae
Cecidomyiidae is a family of flies known as gall midges or gall gnats. As the name implies, the larvae of most gall midges feed within plant tissue, creating abnormal plant growths called galls. Cecidomyiidae are very fragile small insects usually only in length; many are less than long. They are characterised by hairy wings, unusual in the order Diptera, and have long antennae. Some Cecidomyiids are also known for the strange phenomenon of paedogenesis in which the larval stage reproduces without maturing first. In some species, the daughter larvae consume the mother, while in others, reproduction occurs later on in the egg or pupa. More than 6,650 species and 830 genera are described worldwide, though this is certainly an underestimate of the actual diversity of this family. A DNA barcoding study published in 2016 estimated the fauna of Canada alone to be in excess of 16,000 species, hinting at a staggering global count of over 1 million cecidomyiid species that have yet ...

Myrmecophily
Myrmecophily ( , ) is the term applied to positive interspecies Association (ecology) , associations between ants and a variety of other organisms, such as plants, other arthropods, and fungi. Myrmecophily refers to Mutualism (biology) , mutualistic associations with ants, though in its more general use, the term may also refer to commensalism , commensal or even parasite , parasitic interactions. The term "myrmecophile" is used mainly for animals that associate with ants. An estimated 10,000 species of ants (Formicidae) are known, with a higher biodiversity , diversity in the tropics.B. Holldobler and E.O. Wilson, The Ants, Cambridge, Massachusetts: The Belknap Press of Harvard University Press, 1990. In most terrestrial ecosystems, ants are ecologically and numerically dominant, being the main invertebrate predators. As a result, ants play a key role in controlling arthropod richness, abundance, and community structure.K. Fiedler, B. Holldobler, and P. Seufert, "Butterflies and ...

Chaitophorus
''Chaitophorus'' is a genus of aphids first described by Carl Ludwig Koch in 1854. This genus includes roughly 90 to 110 species, and is found in North America, Europe, and Asia. Hosts ''Chaitophorus'' aphids are generally host-specific. They are known primarily from members of Salicaceae, namely ''Populus'' and '' Salix''. However, some species are known from Vitaceae, Apiaceae, and Asteraceae. Identification The morphological differences between species of this genus are fairly subtle. As a result, identification to the species can be challenging, and knowledge of the host plant can be valuable. Ecological relationships Parasitoids such as '' Lysiphlebus salicaphis and Aphelinus aureus'' are known to specialize in this genus. Like many aphids, ''Chaitophorus'' are known to have generally mutualistic relationships with ants. This relationship is described to have independently evolved at least 5 times within the genus.

Salix Exigua
''Salix exigua'' (sandbar willow, narrowleaf willow, or coyote willow; syn. ''S. argophylla, S. hindsiana, S. interior, S. linearifolia, S. luteosericea, S. malacophylla, S. nevadensis,'' and '' S. parishiana'') is a species of willow native to most of North America except for the southeast and far north, occurring from Alaska east to New Brunswick, and south to northern Mexico. It is considered a threatened species in Massachusetts while in Connecticut, Maryland, and New Hampshire it is considered endangered. Description It is a deciduous shrub reaching in height, exceptionally spreading by basal shoots to form dense clonal colonies. The leaves are narrow lanceolate, long and broad, green, to grayish with silky white hairs at least when young; the margin is entire or with a few irregular, widely spaced small teeth. The flowers are produced in catkins in late spring, after the leaves appear. It is dioecious, with staminate and pistillate catkins on separate plants, the mal ...

Insects Described In 1869
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] |
