Part four in a series of ten to twelve which will cover the 2,000 species of Victorian moths. This is the second book of geometrids, covering the Emeralds and allies, adults of the familiar looper caterpillars. They range from small and day-flying to robust and intricately patterned creatures of the night. With 180 species and over 700 images, this book presents every known Victorian moth in these two groups for the first time. A CD-ROM provides over 380 additional pages which contain biology and distributions for each species together with checklists, identification tips and more.
