(Aug 13, 2020) Curt Stager reports on a long-term study of flying insects in Germany that records an astounding 76% drop in the total biomass of flying insects entering their traps over the last 30 years. This is not a decline as happens in a single species, but appears to affect the whole spectrum of species. Martha Foley wonders if this could explain the decline in insect-eating birds that appear around her house, or the steep decline in bug spats Stager observes on his car compared to decades ago. Disturbing news from long-term study and anecdotal observations.
