Thousands of people indifferently pass by crawling, flying, jumping insects, painfully brushing them off, considering them worthless, harmful and useless. But there are people in the world who devote their whole lives to studying these creatures. They call these enthusiasts entomologists because entomology is the science of insects. Those who want to study the world of insects simply need to read the book of the famous French entomologist J.-A. Fabra, because it was a reference book of many famous zoologists N. Drozdov, J. Darrell, B. Grzhimek and others.
