Micropthalma Disjuncta

a fly of the family Tachinidae. The body length is 10–13 mm. The coloration is black-brown with a gray sheen; there is a faint checkerboard pattern on the abdomen. M. disjuncta is distributed throughout southern Europe and southern portions of North America. In the USSR it occurs in the southern European portion and in Middle Asia (northward to Bashkiria). The fly is viviparous. The larvae are deposited on the ground, where they seek out and parasitize the larvae of the subfamily Melolonthinae. M. disjuncta is a natural enemy of Polyphylla fullo and the May beetle (Melolontha), regulating the number of their larvae, which are injurious to many tree species.
