` Although this is an expensive book, it is well produced and has a fabulous colour photograph of a black and yellow liriomyza sp. on the cover. Spencer must be congratulated in producing a book that will become a bible for students of the Agromyzidae and will be widely read by those still to be converted to an appreciation of these most fascinating of files.

' This is a superlative monograph....The drawings...are particularly attractive and useful. One should be extremely grateful for this invaluable combination of world-wide collection, able systematics and plant-host relationships together with the careful assessment of the data collected.
Finally one most congratulate Ann Spencer for her drawings...for once one cam be well satisfied with the Index. Every entomological library, public and private, must quickly obtain a copy. '

' This is the first modern monograph of the Agromyzidae that, besides a vast number of the host plant data, also critically summarizes all main results of the taxonomic research on this group. It should be useful for those who are intersted in furthur research on the taxonomy and ecology of these insects, and also for appliedentomologists. '

' This book should be dipped into by entomologists, chemist and botanists alike. It should be on the library shelf of all institutions interested in plant-insect relations. There is nothing else like it ' Kew Bulletin Herbarium 47:1 1992
