It's worth noting that data was collected by amateurs in the sense that they're doing this on their spare time but some of them are highly regarded in their field. Quote from http://www.sciencemag.org/news/2017/05/where-have-all-insects-gone http://www.sciencemag.org/news/2017/05/where-have-all-insect... Members of the Krefeld society have been observing, recording, and collecting insects from the region—and around the world—since 1905. Some of the roughly 50 members—including teachers, telecommunication technicians, and a book publisher—have become world experts on their favorite insects. Siegfried Cymorek, for instance, who was active in the society from the 1950s through the 1980s, never completed high school. He was drafted into the army as a teenager, and after the war he worked in the wood-protection division at a local chemical plant. But because of his extensive knowledge of wood-boring beetles, the Swiss Federal Institute of Technology in Zurich awarded him an honorary doctorate in 1979. Over the years, members have written more than 2000 publications on insect taxonomy, ecology, and behavior.
