A bee size diptera, with elongated body. Red-brown abdomen with few black hairs protruding; black head and thorax, and dusky-brown transparent wings. There are also two transparent pearly disks at the base of wings, protecting fly's balances.
Seen in a small valley which we baptized a "Valley of butterflies" - the grassland valley is really very small, not more than 100 at its longest side and completely surrounded by a broad-leaved forest, and edged by a small and very clean stream. When we visited, grasslands were covered in a multitude of butterflies, mainly fritillaries.
