Trichogrammatidae
The Trichogrammatidae are a family of tiny wasps in the Chalcidoidea that include some of the smallest of all insects, with most species having adults less than 1 mm in length, with species of '' Megaphragma'' having an adult body length less than 300 μm. The over 840 species are placed in about 80 genera; their distribution is worldwide. Trichogrammatids parasitize the eggs of many different orders of insects. As such, they are among the more important biological control agents known, attacking many pest insects (especially Lepidoptera). They are not strong fliers and are generally moved through the air by the prevailing winds. Their fore wings are typically somewhat stubby and paddle-shaped, with a long fringe of hinged setae around the outer margin to increase the surface area during the downstroke. Males of some species are wingless, and mate with their sisters inside the host egg in which they are born, dying without ever leaving the host egg. Trichogrammatidae h ...

Megaphragma
''Megaphragma'' is a wasp genus in the family Trichogrammatidae The Trichogrammatidae are a family of tiny wasps in the Chalcidoidea that include some of the smallest of all insects, with most species having adults less than 1 mm in length, with species of '' Megaphragma'' having an adult body length .... It contains two of the four smallest known insects, '' Megaphragma caribea'' (170 μm) and '' Megaphragma mymaripenne'' (200 μm).

Megaphragma Mymaripenne
''Megaphragma mymaripenne'' is a very small wasp. At 200 μm ( mm; inch) in length, it is the third- smallest extant insect, comparable in size to some single-celled organisms. It has a highly reduced nervous system, containing only 7,400 neurons, several orders of magnitude fewer than in larger insects (for example, a honey bee has about 850,000). This is the smallest known number of neurons in all insects and in all flying animals. Its average lifespan at adulthood is 5 days. In January 1920, specimens of an unknown insect were collected in Hawaii associated with thrips, to which they were suspected to be egg parasites. The insects were described as a new species and genus ''Megaphragma mymaripenne'', in 1924 by Philip Hunter Timberlake. ''M. mymaripenne'' specimens were next found on 29 March 1927, again with thrips, on the leaf of a genus '' Croton'' plant. On 10 May 1930, specimens were found near thrips and thrips eggs, and mature pupae were found inside the thri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chalcidoidea
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are Parasitoid, parasitoids of other insects, though other life styles are known, with the herbivorous Fig wasp, fig wasps acting as Pollinator, pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm.
