Today I am sending a photo of this interesting colored fly. It was taken handheld in windy weather on the overgrown meadow near my house.
I'm not sure specifying ID of this fly. I found some information that is a parasitic fly from family Tachinidae, maybe Phasia hemiptera-male. If someone has a different opinion, I'll be glad for any information on the ID.
Thank you all for your visit and criticism - this is useful for me. Points (smiling) are not important for me.
Best greetings.


Family: Tachinidae
Subfamily: Phasiinae
Genus: Phasia
Species: hemiptera

Size cca: 10-12 mm

Phasia hemiptera
Czech name: Hbitěnka(Kuklice) polokřídlá

Phasia hemiptera is a tachinid fly found throughout Northern and Southern Europe. It is a strongly sexually dimorphic species, males being more colourful with curved patterned wings. Like most tachinid flies, the female lays her eggs on other insects, the larvae then develop inside the living host, devouring it and eventually killing it. Its main hosts are the forest bug Pentatoma rufipes in the spring, and the green shield bug Palomena prasina in the autumn.

Tachinidae is one of the most diverse and ecologically important families of Diptera. Approximately 10,000 species are described.
Reproductive strategies vary greatly between Tachinid species, largely, but not always clearly, according to their respective life cycles. This means that they tend to be generalists rather than specialists. Comparatively few are restricted to a single host species, so there is little tendency towards the close co-evolution one finds in the adaptations of many specialist species to their hosts, such as are typical of protelean parasitoids among the Hymenoptera.
Larvae (maggots) of most members of this family are parasitoids (developing inside a living host, ultimately killing it). In contrast a few are parasitic (not generally killing the host). Tachinid larvae feed on the host tissues, either after having been injected into the host by the parent, or penetrating the host from outside. Various species have different modes of oviposition and of host invasion. Typically, Tachinid larvae are endoparasites (internal parasites) of caterpillars of butterflies and moths, or the eruciform larvae of sawflies, but some species attack adult beetles and some attack beetle larvae. Others attack various types of true bugs, and others attack grasshoppers; a few even attack centipedes.
Probably the majority of female Tachinids lay white, ovoid eggs with flat undersides onto the skin of the host insect. Imms mentions the genera Gymnosoma, Thrixion, Winthemia, and Eutachina as examples. In a closely related strategy some genera are effectively ovoviviparous (some authorities prefer the term ovolarviparous) and deposit a hatching larva onto the host. The free larvae immediately bore into the host's body. illustrative genera include: Exorista, Voria, and Plagia. Many Tachinid eggs hatch quickly, having partly developed inside the mother's uterus, which is long and often coiled for retaining developing eggs. However, it is suggested that the primitive state probably is to stick unembryonated eggs to the surface of the host.
Many other species inject eggs into the host's body, using the extensible, penetrating part of their ovipositor, sometimes called the oviscapt, which literally means something like "egg digger". Species in the genera Ocyptera, Alophora, and Compsilura are examples. Yet another strategy of oviposition among some Tachinidae is to lay large numbers of small, darkly coloured eggs on the food plants of the host species. Sturmia, Zenillia, and Gonia are such genera. Usually only one egg is laid on or in any individual host, and accordingly such an egg tends to be large, as is typical for eggs laid in small numbers. They are large enough to be clearly visible if stuck onto the outside of the host, and they generally are so firmly stuck that eggs cannot be removed from the skin of the host without killing them.
