[Note Guidelines] Photographer's Note
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.

A typical characteristic of this family is the fact that most of them are parasitoids (the larvae develop inside a living host, ultimately killing it), and a few are parasitic (do not kill the host). Larvae are endoparasites (internal parasites) of caterpillars of butterflies and moths, adult and larval beetles, sawfly larvae, various types of true bugs and grasshoppers, rarely in centipedes, with usually only one grub. Only a few species are host species-specific. 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.


Archytas Species Tachinid flies are however regarded as pests by silkworm rearers. One particularly noted species is the Uzi fly (Exorista bombycis).

Reproductive strategies are highly variable between species. The female may lay her white oval eggs on the skin of the host insect, or insert the egg 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, causing death, except in some rare parasitic species.

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), bare (sometimes plumose) arista. The calypters (small flaps above the halteres) are usually very large. Their fourth long vein bends away sharply.

Adult flies feed on flowers and nectar from aphids and scales. As many species typically feed on pollen, they can be important pollinators of some plants, especially at higher elevations in mountains where bees decrease in numbers.

The taxonomy of this family presents many difficulties. It is largely based on morphological characters of the adult flies, but also on reproductive habits and the immature stage.

Hi Luis
I've never seen such a good close up of a fly before. It's amazing to see all of the tiny hairs so clearly. Excellent DOF, colour and composition. Interesting notes too.

Hola Primo,

What an amazing macro of this fly! Perfect details of the entire insect. I can't believe all the little hairs! Wonderful pose on the pretty flower. Background and composition are superb.

Jane

Hi Luis,
This is a detailed macro with agreeable tones of colors and perfect exposure. I would have composed it a little less centered but this is a very minor nit and question of personal taste. Greetings,
Claudine

Gee Luis you sure put that Nikon at it's best. I was not aware that such good quality could come....no I go look at lens...BRB...dang..and its the stock 55 MM too...holy cow...Nikon rules I'll tell ya that...You have mastered it well and this image shows why!

Hola Luis,
Extraordinario macro de esta mosca.
El trabajo de iluminacion, exposición y enfoque son excelentes, y producen todos esos ricos y nítidos detalles en el insecto.
Me gusta la profundidad de campo, que con ese fondo difuso aísla perfectamente el sujeto.
Magnífica foto y gracias por compartirla.
Un gran saludo,

Hi Luis.
Outstanding macro picture. I like all in it. Despite I do not like flies this case is exclusive. Fantastic sharpness and details of the insect and flower. So great exposure and reproduction of all different colour tones. POV and composition of the image cannot be better. BG is unusual and fine. Bravo. Superb job.
