Diplolepididae
Diplolepididae is a Family (biology), family of small Gall, gall-inducing wasps. Until recently these wasps were included in the Cynipidae, gall wasp family (Cynipidae) but were moved to their own family based on genetic and Morphology (biology), morphological features. It contains two Subfamily, subfamilies: Diplolepidinae and Pediaspidinae. Diplolepidinae includes about 60 species in two Genus, genera (Diplolepis (wasp), ''Diplolepis'' and ''Liebelia''), all of which induce galls on roses in which the larvae live and feed. This subfamily was formerly included in Cynipidae as the tribe Diplolepidini. Pediaspidinae is composed of two Monotypic taxon, monotypic genera: ''Himalocynips'' and ''Pediaspis''. The biology of this subfamily is poorly known, though ''Pediaspis aceris'' induces galls on a species of maple. This subfamily was formerly included in Cynipidae as the tribe Pediaspini.

Gall
Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls can be such highly organized structures that their cause can be determined without the actual agent being identified. This applies particularly to insect and mite plant galls. The study of plant galls is known as cecidology. Anatomy Shape and size Galls develop on various plant organs, providing nutrition and shelter to inducing insects. Galls display vast variation in morphology, size, and wall composition. The size of insect galls can range significantly, from approximately two inches in diameter to less than one-sixteenth of an inch. Some galls are so small that they are merely slightly thick ...

Cynipoidea
The Cynipoidea are a moderate-sized hymenopteran superfamily that presently includes seven extant families and three extinct families, though others have been recognized in the past. The most familiar members of the group are phytophagous, especially as gall-formers, though the actual majority of included species are parasitoids or hyperparasitoids. They are typically glossy, dark, smooth wasps with somewhat compressed bodies and somewhat reduced wing venation. It is common for various metasomal segments to be fused in various ways (often diagnostic for families or subfamilies), and the petiole is very short, when present. With the exception of the Cynipidae (the gall wasps), it is a poorly known group as a whole, though there are nearly 3000 known species in total, and a great many species are still undescribed, mostly in the Figitidae. Each of the constituent families differs in biology, though life histories of one of the families ( Liopteridae) are still largely unknown. ...

Diplolepis (wasp)
''Diplolepis'' is a genus of approximately fifty species of gall-inducing wasps in the family Diplolepididae. The larvae induce galls on wild Rose, roses (''Rosa''), and rarely on domestic roses. Description Adults are small () with a strongly arched mesosoma giving them a hunched appearance. Coloration ranges from entirely orange to reddish-brown or black. Larvae are legless and cream-colored with a weakly defined head. Galls formed by a given species can usually be distinguished from those of other species by the shape, size, placement, and ornamentation (smooth or spiny) of the gall, together with the identity of the host plant. However, gall Morphology (biology), morphology can be modified by the presence of inquilines and parasitoids. Some species induce galls on leaves, while others induce galls on stems or adventitious shoots. Depending on the species of wasp, galls may be single-chambered or multi-chambered, and detachable or integral. Range ''Diplolepis'' species oc ...

Hymenoptera Families
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 reach adulthood. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maple
''Acer'' is a genus of trees and shrubs commonly known as maples. The genus is placed in the soapberry family Sapindaceae.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, June 2008 nd more or less continuously updated since http://www.mobot.org/MOBOT/research/APweb/. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Only one species, '' Acer laurinum'', extends to the Southern Hemisphere.Gibbs, D. & Chen, Y. (2009The Red List of Maples Botanic Gardens Conservation International (BGCI) The type species of the genus is the sycamore maple ''Acer pseudoplatanus'', one of the most common maple species in Europe.van Gelderen, C. J. & van Gelderen, D. M. (1999).

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Rose
A rose is either a woody perennial plant, perennial flowering plant of the genus ''Rosa'' (), in the family Rosaceae (), or the flower it bears. There are over three hundred Rose species, species and Garden roses, tens of thousands of cultivars. They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp Thorns, spines, and prickles, prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through pinks, reds, oranges and yellows. Most species are native to Asia, with smaller numbers native to Europe, North America, and Northwest Africa. Species, cultivars and hybrid (biology), hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses to climbers that can reach seven meters in height. Different species hybridize easily, and this has been use ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
