Eric LoPresti By Jake Buehler Some plants may use an odd, yet simple defensive tactic against insect herbivores: sand. New research suggests that some plants use sand grains as an unappetizing and abrasive armour. Psammophorous (“sand-carrying”) plants have sticky surfaces to which sand adheres. The coating was thought to somehow protect the plants against herbivorous insects, but this was only formally tested in 2016. Eric LoPresti of the University of California, Davis and his colleagues confirmed that plants with a coating of sand are eaten less (Ecology, doi.org/chmj). However,
