April showers bring May flowers. What do May flowers bring? June bugs!
And would you not know it; entomology, the scientific study of insects, began in the 16th century, it was not recognized as a specific branch of science until the 1800s. At the turn of the last century only 20,000 have been identified and classified. Now there are upwards of 1.3 million species. They consist of two thirds of all known life forms and scientists find new ones every day. There are quintillion insects in the world, at last count.
To think these men in knickers and trousers hunched over the ground dually scribing and illustrating with painstaking detail of each bug they came across. Perhaps you ponder, why on earth would one study these creepy crawlers? There is actually sound logic, I assure you. Societies are compelled out of necessity to study these organisms to protect themselves from illness, to prevent crop related destruction, alleviate themselves from the irritation of them, track the ecosystem of a place, and possible healing or profitable properties (such as crushed insects to create dyes for textiles.). Of course, it really begins to satisfy a curiosity about the world around us. At some time in the life of a child, s/he is going to take a stick and poke a bug. It just happens.
