Elizabeth A. Bernays

Elizabeth A. Bernays (1940 – 5 March 2024) was an Australian entomologist who was a Regents Professor at the University of Arizona. She was known for studies of physiological, behavioural, and ecological interactions between plants, herbivorous insects and their predators. Bernays worked on the feeding behaviour of a variety of insects including aphids, grasshoppers, and hawkmoths. She was known for championing the idea that predation drove many insects to specialise on a few species of hostplants, rather than specialisation being solely the outcome of a chemical arms race between plant and insect herbivores.

Early life Educated at the University of Queensland, Australia, she moved to London to teach high school students; she subsequently studied for a PhD there. Prior to moving to the University of Arizona, she was a professor at the University of California, Berkeley. Her research into the feeding behaviour of insects helped guide interventions designed to minimise crop pest damage.

Academic honours In 1986, she received the Vatican's highest scientific honour, the Pius XI Gold Medal of the Pontifical Academy of Sciences. Late career activities After retirement, Bernays studied for a master's degree in creative writing at the University of Arizona. Her second memoir, Across the Divide: The Strangest Love Affair, describes her personal and creative relationship with her wife Linda Hitchcock which included collaborating on children's nature books and travelling the southwestern U.S.

Personal life She was married to the English entomologist Reginald Frederick Chapman until his death in 2003. She met Linda Hitchcock, photojournalist in 2004 and subsequently married in 2018 .
