From the Agricultural Research Service's weekly news report comes this story about the arrival of the Old World hunter fly (Coenosia attenuata) here in the U.S. The fly was first discovered in New York back in 1999, but no one is quite sure how the species got here. As its name indicates, the Old World hunter fly is a predator, dining upon a variety of other fly species, as well as leaf miners and leafhoppers. Interestingly, some scientists are taking the "glass half full" point of view here, looking at the fly as a potential biological control for greenhouse pests. I want to know what else this thing is eating.
