Pison
''Pison'' is a cosmopolitan genus of wasps within the family Crabronidae. The genus comprises 145 described species, although many species, especially in South America remain undescribed.Bohart, Richard Mitchell, and Arnold S. Menke. Sphecid wasps of the world: a generic revision. University of California Press, 1976. Distribution The genus is found throughout the tropical and warm temperate regions of the world, but does not extend into the more northerly temperate regions. Most species occur in the Southern Hemisphere, with a third of species occurring in Australia. This distribution pattern has been thought to indicate that the genus was once much larger, and has declined in the face of competition with more competitive wasp genera, leaving the genus largely concentrated in geographically-isolated regions.Turner, Rowland E.

Crabronidae
The Crabronidae are a large paraphyletic group (nominally a family) of wasps, including nearly all of the species formerly comprising the now-defunct superfamily Sphecoidea. It collectively includes well over 200 genera, containing well over 9000 species. Crabronids were originally a part of Sphecidae, but the latter name is now restricted to a separate family based on what was once the subfamily Sphecinae. Several of the subfamilies of Crabronidae are often treated as families in their own right, as is true of the most recent phylogenies (example below). Phylogeny This phylogenetic tree is based on Sann ''et al.'', 2018, which used phylogenomics to demonstrate that both the bees (Anthophila) and the Sphecidae arose from within the former Crabronidae, which is therefore paraphyletic, and which they suggested should be split into several families; the former family Heterogynaidae nests within the Bembicidae, as here defined. These findings differ in several details from st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximilian Spinola
Maximilian Spinola ( it, Massimiliano Spinola; July 10, 1780 – November 12, 1857) was an Italian entomologist. Background Spinola was born in Pézenas, Hérault, France. The family of Spinola was of very long standing and had great wealth and power in Genoa. Maximilian Spinola was a descendant of the famous Spanish General Ambrogio Spinola, marqués de los Balbases (1569–1630) and much of his wealth derived from land held in Spain and South America. He was linked to Camillo Pallavicini. Research He received many insects from his properties in Spain and South America. He also made extensive, and expensive purchases especially of large showy tropical beetles and wasps. His entomological contributions were mainly in the orders Coleoptera, Hymenoptera and Hemiptera. Spinola made very important contributions to entomology, describing many taxa, especially in Spinola M. M., 1850.''Tavola sinottica dei generi spettanti alla classe degli insetti Arthroidignati, Hemiptera Linn., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species ...

Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
