In 1879, Jean-Henri Fabre wrote a book about insects called Souvenirs entomologiques. Today it’s considered a classic of entomology. An English translation, with some absolutely beautiful illustrations like the cicadas pictured above, was published in 1921.
You can read the full book online for free. Yes, both versions. The original French work is available at Gallica. Meanwhile, you can read the full English version at Google Books. Very neat!
