An illustrated, practical survey of Australian insect fauna that combines accessible descriptions of anatomy, life cycles, and habitats with taxonomic keys and notes on economic significance. It reviews major orders and families, includes fossil evidence, and offers guidance on collecting, preserving, and studying specimens. Hundreds of plates and figures aid identification while chapters discuss species habits, host plants, nests and galls, and pest control considerations. The text also summarizes museum holdings, type specimens, and relevant literature, aiming to serve both general readers and students by balancing popular exposition with scientific detail.
