Spencer, K.A. 1990. Host Specialization in the World Agromyzidae (Diptera). Kluwer Academic Publishers, Dordrecht, the Netherlands. xii + 443 pp.

Phytophagous insects represent a very particular group of organisms. Firstly, their number amounts to more than one quarter of all recent species (excluding fungi, algae and microbes) and together with the green plants on which they feed they form almost one half of all living species described so far. Secondly, their overwhelming majority shows very narrow host plant specialization, that is they feed only on one or a few, mostly closely related plant species, a characteristic that led J. H. Fabre to elaborate the notion of the 'insects' botanical instinct' a century ago.
