Rambo Tribble (1273454) writes "At the same time that bee populations are crashing, researchers have found that another pollinator group, moths, is being adversely affected by chemicals in the air. The moths' ability to discern the floral species they need to target is diminished by other scents from a variety of human-imposed sources. These range from non-native plants to vehicle exhaust. As one researcher succinctly puts it, "The total combination of dynamic odors, including floral signature odors as well as anthropogenic pollutants, can affect the success of olfactory-based resource finding."
