Fly By Day

People often question whether midges and mosquitos serve any useful purpose on the planet (the same is sometimes said of wasps). There is, however, an interesting correlation between the spraying of neonicotinoid insecticides (the chemicals that seemingly endanger bees in the UK) in rice paddy fields and collapsing stocks of fish and eels that live in these locations (https://www.theguardian.com/environment/2019/oct/31/fishery-collapse-confirms-silent-spring-pesticide-prophecy). The fact that the fish largely feed on insects suggests that they may be being starved into declines.
