Description:
Ventral views of the abdomens’ of both H. pakistanae and H. balciunasi showing the morphology of the external male genitalia. Note the cruciate or crossed macrochaetae in both species, a configuration that is not found in native Hydrellia species. The primary difference between the two introduced species is the size and shape of the macrochaetae. In H. pakistanae, the macrochaetae are smaller and needle-like in comparison to H. balciunasi where the macrochaetae are larger and spoon-shaped at the ends
