Tachina grossa

This species can be found throughout most of Western Europe, east to Asia and in Mongolia.^[2][3]

These flies mainly inhabit dry open meadows, peat land, moors, forests, heaths and gardens.

Tachina grossa can reach a length of 15–19 millimetres (0.6–0.7 in). This species of fly is one of the largest throughout much of its range and is the largest tachinid in Europe. These flies are very distinctive, being hairy and with a black thorax and abdomen. In flight they resemble a bumblebee. The inflated, curved, all-black abdomen is covered with stiff, straight bristles, especially at the end of the abdominal segments. The head is bright yellow, with occipital yellow bristles. The large compound eyes are dark brown. The forehead forms a sharp angle at the base of the antennae. Maxillary palpi are thin, filiform. Wings are hyaline, yellowish-brown at the base.^[4][5][6][7]
