When he was less than 19 years old, he determined to study insects. Later, he obtained a master's degree and a doctorate in natural sciences through self-study. In 1880, he used a small amount of money he had saved to buy an old house on wasteland near the rural town of Serignan to further study live insects. His plan was about to become a reality. He was in a good mood and gave this residence a funny nickname in the local Prosven language - Barren Stone Garden. Year after year, he guarded his beloved Barren Stone Garden and worked hard at his best. , tirelessly engaged in unique entomological research, and wrote the fruits of his labor into volumes of "Insects". In this way, he spent the remaining 35 years of his life peacefully, lonely, joyful, and miserable.

The main content of "Insect Diary" focuses on entomological issues. It also includes some biographical articles about experiences and memories of the past, some discussions on solving theoretical problems, and a small amount of texts with popular science knowledge. 1910 Law In the preface to the publication of the ten-volume hardcover version of "Insects", Bull said: "It is a pity that I am forced to interrupt these studies now. You must know that engaging in these studies is the only comfort I have received in my life. I have read all over the world. , I know that insects are one of the most colorful groups. Even if I can gain some more strength, and maybe even live a few more long lives, I still can't fully understand the benefits of insects."

One day in November 1915, this giant who played the vibrato of human destiny with insects as his piano passed away.
