Thrips remain a mysterious group of insects because up to now they have been studied by only a few specialists. A factor limiting their appeal has been the problem of identification. Some species are genuinely difficult to separate, but others can be named fairly easily and some can even be recognised alive in the field. The keys in this book have been designed to enable anyone with access to a good microscope to overcome the taxonomic hurdle in order to explore the unusual natural history and behaviour of thrips.
