Tachinidae is a large and rather variable family of true flies within the insect order Diptera, with more than 8,200 known species and many more to be discovered. There are over 1300 species in North America. Insects in this family are commonly called tachina flies or simply tachinids.
They occur in almost all habitats all over the world. There are Neotropical, Nearctic, Afrotropical[1], Palaearctic, Oriental, Australasian and Oceanic species.
Larvae (maggots) of most members of this family are parasitoids (they develop inside a living host, ultimately killing it), and a few are parasitic (they do not kill the host). They are endoparasites (internal parasites) of caterpillars of butterflies and moths, adult and larval beetles, sawfly larvae, various types of true bugs and grasshoppers, and (rarely)centipedes, with usually only one grub. Only a few species are restricted[by whom?] to one host species. As such, many are important natural enemies of major pests. Some species are being used in biological pest control. Many important pests are suppressed by tachinids. Many species of tachinid flies have been introduced into North America from their native lands as biocontrols to suppress populations of alien pests.
Certain tachinid flies are, however, regarded as pests by silkworm rearers. One particularly noted silkworm pest is the Uzi fly (Exorista bombycis).
Reproductive strategies vary greatly between species. The female may lay white oval eggs on the skin of the host insect, or insert eggs into the host's body, or leave them in the host's environment, as for example on leaves, where the host will ingest them. Some tachinids that are parasitoids of stem-boring caterpillars deposit eggs outside the host's burrow, letting the larvae do the work of finding the host itself. In other species, the maggots use an ambush technique, waiting for the host to pass and then attacking it and burrowing into its body. The larvae feed on the host tissues.
Tachinid flies are extremely varied in appearance. Adult flies may be brilliantly colored and then resemble blow-flies (family Calliphoridae), or rather drab, and then resemble house flies. But tachinid flies are more bristly and more robust. They have three-segmented antennae, a diagnostically prominent postscutellum bulging beneath the scutellum (a segment of the mesonotum), and bare (sometimes plumose) arista. The calypters (small flaps above the halteres) are usually very large. Their fourth long vein bends away sharply.

Wunderschoen Guten Abend, Rose!
Great macro capture of the fly with superb sharpness and great natural colors!
The POV and DOF are perfect and wonderful use of the natural light, make this a very eye-catching capture. The eyes of fly, are well shown.
I must mention that your macro quality is getting better and better day by day...& this is not the technical aspect of the camera you possess but your dedication and motivation, that make it into reality.
Very well done, my friend!
Schoen Tag noch,
Paras
PS: Sorry, Rose! I don't have points to award to this picture :( though I would love to do so.
Ciao Rose, wonderful fly on a beautiful flower, fantastic details, splendid sharpness and great colors, very well done, ciao Silvio
Hello Rose.

Ciao Rose
This is an attractive palette, with pure clean colours!
Excellent details in the fly, pin sharp and the
DoF isolates the subject nicely...
Good point of view and I admire the silky-crisp
texture in the wings!
Greetings,
Sergio
