Book Recommendation: Micro ladybirds of Britain and Ireland

One day all field guides will be this good.

In many ways micro ladybirds ("inconspicuous ladybirds") are a perfect group for a field guide. With around 50 ladybird species in Britain, half of these are the familiar spotted ladybirds. The remaining 25 species, the "inconspicuous ladybirds", are the subject of this book. The illustrations are excellent, the descriptions of the identifying features clear and concise and the comparison plates of similar species particularly useful. A microscope is not required to use this guide, all you need is a 10x hand lens, which will reveal most of the structural features of importance.

A real gem of a book and at a bargain price. You'd be daft not to buy it:
