Trigonospila is a small genus of flies
in the tribe Blondeliini
of the Family Tachinidae
. Trigonospila is native to, but not endemic in, Australia
and common in parts of the Australian landscape. Species can often be found resting on the upper surface of vegetation. The genus can be found in other parts of the world including Europe

and abdomen
. There are two whitish bars on the thorax; one adjacent to the transverse suture, and the second adjacent to the scutellum
. There may also be a white triangle on the tip of the scutellum, and the subscutellum is usually white. Abdominal colouration varies between species however it is typical that there are three whitish bars on the abdomen; one at the anterior margin of the third, fourth, and fifth abdominal tergite. The width of these bars differs between species.

Scutellum
The scutellum is the posterior portion of either the mesonotum or the metanotum of an insect thorax; however, it is used almost exclusively in the former context, as the metanotum is rather reduced in most insect groups. In the Hemiptera, and some Coleoptera, the scutellum is a small triangular...
