His body horror masterpiece 'The Fly' (1986) uses insect transformation as a profound exploration of disease, decay, and loss of human identity.

In 'The Silence' (1963), insects and biological imagery symbolize human alienation and the breakdown of communication in society.

His films frequently employ insects and nature as metaphors for human disconnection and existential anxiety, particularly in 'L'Avventura' (1960) and 'Blow-Up' (1966).
