"Synthesis: the mixing of different ideas, influences, or things to make a whole that is different, or new" (dictionary.cambridge.org/dictionary/english/synthesis). This is what Michael Samways set out to provide in this 500+ page volume. I guess this much space is required just to begin tackling a problem with millions of actors. Millions of actors that are now in the middle of an apocalyptic movie, one of those B-rated ones, where there is a lot of gore and blood. Try writing the script of this movie. Your job is to describe the fate of all the actors, to which you must give a name, describe how they make a living, and how they are related to each other. Now, create some threat, maybe global warming, maybe wipe out of entire nations. Quantify how many were sacrificed, but do not forget about the survivors. Describe what strategies were used to save them. Try to give a happy ending, so that people leave the theater with some sense of hope. Five hundred pages do not seem that much anymore, do they? Maybe an encyclopedia would be enough? Samways has been one of the strongest advocates for insect (and arthropod) conservation for many decades. Even before anyone cared for them, far from the current growing interest in the subject, he was already fighting for insects and other invertebrates. He was right there with Ed Wilson, Terry Erwin, Tim New, and the very few others who saw biodiversity for what it is, not for what it looks like. Why should the rest of us care about the "little things that run the world" (Wilson 1987)? This new book starts precisely there: tackling the perception problem. Describing the rise and fall of insects, their diversity, their roles in ecosystems, how important they are to us, and the scales at which we can move to take effective action. Particularly insightful is the philosophical aspect of insect conservation. If 99% of the species that ever lived are now extinct, why should we care about the current 1%? Will not new insect species, as for all taxa, just evolve and replace the disappearing ones? Samways argues that our sentience makes the difference. We know we are causing extinctions, and we know we can halt them. Insect conservation psychology (Simaika & Samways 2018) will play a major role in the future, and there is the need for advocates from all areas, from entomology to sociology, to pedagogy, to the arts.
