Aphelopus Varicornis
''Aphelopus'' is a genus of insects belonging to the family Dryinidae. It is recognizable by only one costal cell surrounded by pigmented veins. The genus was first described by Dalman in 1823. The genus has cosmopolitan distribution.

Insect
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryinidae
Dryinidae is a cosmopolitan family of solitary wasps. Its name comes from the Greek ''drys'' for oak: Pierre André Latreille, Latreille named the type genus ''Dryinus'' because the first species was collected in an oak plant in Spain. The larvae are parasitoids of the nymphs and adults of Auchenorrhyncha. Dryinidae comprises approximately 1900 described species, distributed in 17 subfamilies and 53 genera. Description The adult wasp can measure from 0.9 to 5.0 mm in length and in some cases can reach 13 mm. The body of the adult wasp has a 'waist' where it is constricted in the middle. The rear legs have spurs which may be used for grooming. The antennae have 10 segments. Many species have a marked sexual dimorphism, where males are totally different from the females in the size and shape of the body. Males have wings while females are often wingless and resemble worker ants. The ovipositor is retractable and not visible when retracted. Life history The female dryinid ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
