George McGavin is an entomologist, explorer and broadcaster, who has spread the word about the importance of insects to audiences in their millions.

Born in Glasgow, he grew up in Edinburgh where he studied zoology at university. Following a PhD in entomology, he went on to teach and research at the University of Oxford. He gave up his post as the assistant curator of the university’s Museum of Natural History after 25 years to follow his dream of becoming a television presenter.

He has presented documentaries from far-flung locations including Borneo, Guyana and New Guinea. He has made it his life’s work to uncover the mysteries of the largely uncatalogued world of invertebrates which he says makes up close to 80% of life on earth.

In 2018 he was diagnosed with a rare form of skin cancer and the following year he turned the camera on himself to present a very personal programme about his diagnosis and treatment.
