This volume treats one of the more neglected families of Heteroptera in Denmark. The 77 presently known species are dealt with in detail, and the book is illustrated throughout with beautiful colour photos. Distribution maps to all species are given. Introductory chapters deal with: historical background, evolution history; systematics and nomenclature; habitus; life cycle; food; enemies & defence; habitats; status & distribution; how to study these bugs; and the Danish families. This is the first ever complete study of the Danish Lygaeidae.
