Part seven in a series of ten to twelve which will cover the 2,000 species of Victorian moths. This part is the final of the geometrids covering the bark moths and others. The bark moths are often considered as 'typical' geometrids. The book reveals their intricate and subtle patterns that render them almost invisible against tree bark. With the addition of some small, related groups, this book presents over 100 species and 850 images. The included CD-ROM provides 250 pages with additional information on identification, distribution and biology for each species.
