Helaeomyia Petrolei
The petroleum fly, ''Helaeomyia petrolei'', is a species of fly from California, USA. The larvae feed on dead insects and other arthropods that become trapped in naturally occurring petroleum pools, making this the only known insect species that develops in crude oil, a substance which is normally highly toxic to insects. Description Adults are about 5 mm long, with black bodies, except for lighter cheeks. The halteres are yellowish, with white knobs. The densely hairy eyes are nearest at the middle of the face. The third joint of the antennae is slightly longer than the second, the spine of the latter not reaching beyond the apex of the antennae. The hyaline wings are tinged with gray on nearly the entire costal half, except sometimes having a spot toward the apex of the submarginal cell. The apex of the second vein is nearly twice as far from the first as from the apex of the third vein. Biology While the larvae normally swim slowly near the surface of the oil with the t ...

Taxa Named By Ezra Townsend Cresson
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachycera Genera
The Brachycera are a suborder of the order Diptera. It is a major suborder consisting of around 120 families. Their most distinguishing characteristic is reduced antenna segmentation. Description A summary of the main physical characteristics is: * Antenna size (with eight or fewer flagellomeres) is reduced. * The maxillary palp (an elongated appendage near the mouth) has two segments or fewer. * The back portions of the larval head capsule extend into the prothorax (the anterior part of the thorax, which bears the first pair of legs). * Two distinct parts make up of the larval mandible (lower jaw). * The epandrium and hypandrium of the genitalia are separated in males. * No premandible is present on the lower surface of the labrum (the roof of the mouth). * The configuration of the CuA2 and A1 wing veins is distinct. Brachyceran flies can also be distinguished through behavior. Many of the species are predator Predation is a biological interaction where ...

Ezra Townsend Cresson
Ezra Townsend Cresson, also Ezra Townsend senior (18 June 1838, in Byberry – 19 April 1926, in Swarthmore) was an American entomologist Entomology () is the scientific study of insects, a branch of zoology. In the past the term "insect" was less specific, and historically the definition of entomology would also include the study of animals in other arthropod groups, such as arach ... 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''. References * Essig, E.
