You might have noticed the Google tribute to Maria Sibylla Merian (2 April 1647 – 13 January 1717) who was a nature illustrator who also contributed to our knowledge of insects and plants, especially the life cycle of Lepidoptera.
According to Wickepedia: Merian worked as a botanical artist. She published collections of engravings of plants in 1675, 1677, and 1680. She collected and observed live insects and created detailed drawings to illustrate insect metamorphosis. In her time, it was very unusual that someone would be genuinely interested in insects, which had a bad reputation. Merian also described many other details of the evolution and life cycle of the insects she observed. She could, for example, show that each stage of the change from caterpillar to butterfly depended on a small number of plants for its nourishment. She noted that as a consequence the eggs were laid near these plants.Merian was one of the first naturalists to observe insects directly. This approach gave her much more insight into their lives and was contrary to the way that most scientists worked at the time.
