Distribution

This species can be found in the entire Palaearctic ecozone, across Europe as far north as Scandinavia and European Russia. It is also present in Israel, North Asia, east to China, Mongolia, Korea, Japan and in North Africa.[3][4][5]

Habitat

These flies inhabit the vegetation of humid regions, meadows, woodland, forests, forest edges, clearings, heath and moorland and natural gardens.[6][7][8]

Description

Tachina fera can reach a length of 9–14 millimetres (0.35–0.55 in),[6][7] with a wingspan of 16–27 mm.[8] These tachinids show a grayish upperside of the thorax, due to dense pollinosity, with regular black stripes. The abdomen is yellow orange with a wide black dorsal stripe ending in a point . They are bristly on the thorax and abdomen, especially towards the tip, where they have long thorn-shaped, protruding black bristles. Close to the thorax there is a striking, orange-red and shiny 'bump' called postscutellum, with a thin black edge. The head is yellowish colored, with long antennae, whose second segment is yellow, while the third, much shorter, is black. The back of the head shows yellowish hairs and the large compound eyes are red in color. The size of the eyes in relation to the head is gender dependent. The palps of the mouthparts are long, thin and thread like. The wings are slightly yellow tinged, show a brownish yellow veining and are yellow brown at the base. Calyptrae are whitish yellow. The legs are predominantly yellowish, but in the male they are usually dark with a yellow tip.

This species is very similar to Tachina magnicornis, that is a little smaller, has a medial dorsal band forming lozenges and that does not terminate in a point.

Biology

There are two generations per year, as this species is bivoltine. Adults can be seen from the end April to the end June and from mid-July to mid-October.[7][8] They feed on nectar and pollen of flowers, especially of Asteraceae (Cirsium arvense) and Apiaceae (Heracleum sphondylium).[8] Females does not lay eggs, like a parasitic wasp, in the caterpillar, but on the leaves of a potential nutritive plant of the host caterpillars. When the eggs hatch the young larvae enter the body of the caterpillars (one larva per caterpillar) and eat them from the inside. In fact larvae are parasitoids of the caterpillars and larvae of other young insects, but mainly of moths in the families Noctuidae and Lymantriidae. In Britain afflicted species include the broom moth (Ceramica pisi), the dun-bar (Cosmia trapezina), small Quaker (Orthosia cruda) and common Quaker (Orthosia cerasi).[7] They also parasitize caterpillars of the gypsy moth (Lymantria dispar), the black arches (Lymantria monacha), and the pine beauty (Panolis flammea).[9] Pupation occurs outside the host in the soil litter. After about two weeks the adult flies will appear. This species has a potential economic importance in forest pest control.[10][11][12]
