Tachina agnita is a species of fly in the genus Tachina of the family Tachinidae that is endemic to Belgium. [2]
Flies are insects with a pair of functional wings for flight and a pair of vestigial hindwings called halteres for balance. They are classified as an order called Diptera, that name being derived from the Greek δι- di- "two", and πτερόν pteron "wings". The order Diptera is divided into two suborders, with about 110 families divided between them; the families contain an estimated 1,000,000 species, including the familiar housefly, horse-fly, crane fly, and hoverfly; although only about 125,000 species have a species description published. The earliest fly fossils found so far are from the Triassic, about 240 million years ago; phylogenetic analysis suggests that flies originated in the Permian, about 260 million years ago.
Tachina is a genus of large flies in the family Tachinidae. There are approximately 600 species worldwide. Most have larvae that are parasitoids of Lepidopteran caterpillars.
The Tachinidae are a large and variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. Over 1300 species have been described in North America alone. Insects in this family commonly are called tachina flies or simply tachinids. As far as is known, they all are protelean parasitoids, or occasionally parasites, of arthropods.
