Acridomyia
Acridomyia is a genus of flies in the family Anthomyiidae, established by Stackelberg in 1929. The genus is native to Eurasia and contains parasitic species that attack grasshoppers (Acrididae). A. sacharovi has been investigated as a potential biological control agent for grasshopper populations in North America.
Devia prospera
Devia prospera is a rove beetle (Staphylinidae: Aleocharinae) described by Erichson in 1839. The species has a Holarctic distribution, occurring naturally across northern Eurasia from Europe through Russia to Japan, and has been introduced to North America where it is now established across Canada and the northern United States. As a member of the diverse rove beetle family, it inhabits various terrestrial environments where these beetles are typically found.
Himacerus apterus
tree damsel bug
Himacerus apterus, commonly known as the tree damsel bug, is a predatory hemipteran in the family Nabidae. It is native to Eurasia and was first recorded in North America from eastern Nova Scotia between 1943 and 1989. The species exhibits wing polymorphism, with most individuals being brachypterous (short-winged). It is a generalist predator of small arthropods and has been considered for biological control applications, though cannibalism complicates mass rearing efforts.
