Atylostoma tricolor exhibits the characteristic morphology of a tachinid fly. Observations from the TreeOfLife-200M dataset indicate that the species possesses a robust, bristly body typical of the family Tachinidae.[1] The thorax and abdomen are covered in prominent, dark setae (bristles). The wings are clear and held in a characteristic position, and the eyes are relatively large, occupying a significant portion of the head.[1]
Atylostoma tricolor (Mik, 1883) is a rare, Eurosiberian species belonging to the tribe Leskiini within the family Tachinidae.[2]
The species is known to be a parasitoid that develops within the caterpillars of Eurrypara hortulata (Lepidoptera: Pyralidae), which feed on common nettle (Urtica dioica). It is a univoltine species, with adults typically active between June and August.
The species is widely distributed but rare across Eurasia. In Europe, it has been documented in Austria, Belgium, Byelorussia, France, Germany, Hungary, Poland, Slovakia, Slovenia, Switzerland, and Western Russia. In Asia, it has been recorded in the Caucasus, the Baikal region, the Russian Far East, and Japan (Hokkaido).
