Scientific art may be presented either through final publications or within the pages of scientists' field notes. The latter often serve as the basis for more formal publication illustrations or provide details upon which authors may base their written descriptions of species or environments. In many cases, they help reveal new insights into an organism's physiology, morphology and ethology.
Entomologists Maria Sibylla Merian and Robert E. Silberglied offer excellent examples of the importance of art in scientific investigation.
Maria Sibylla Merian, born on this day (April 2) in Frankfurt in 1647, is recognized as one of the most significant contributors to the field of entomology. Raised within a family of artists, Maria developed a fascination with insects, especially moths and butterflies, at an early age. By observing and sketching the silkworms that fed on the mulberry in her yard, she discovered that the silkworms turned into moths. She soon expanded her investigations to include as many caterpillars as she could, realizing that each of them metamorphisized into various butterflies and moths.
At the age of 28, Maria published her first book of botanical illustrations in 1675, entitled Neues Blumenbuch. In 1699, she was awarded a grant by the then-governor of the Dutch colony of Suriname to travel with her daughter, Dorothea, to South America to explore and illustrate local animals and plants. She spent two years traveling around Suriname, including what later became known as the French, Dutch and British Guianas, illustrating wildlife with particular attention to capturing insect metamorphosis. In 1705 she published her work in Metamorphosis Insectorum Surinamensium with 60 plates depicting the full life cycle of many Suriname insects.
Maria's illustrations were important and revolutionary for a number of reasons. The observations and evidence they displayed helped overturn the prevailing theory of the time that insects spontaneously generated from mud. Additionally, Maria drew her subjects from life in their natural environments. Most naturalists of the day illustrated species from dead, preserved specimens, which contributed to a lack of knowledge about the true life cycle and origin of insects. Finally, Maria also portrayed the host plant for the species she studied and even illustrated the damage the insects left on the plants.
Sadly, Maria's Suriname expedition was cut short by an illness that forced her to return to the Dutch Republic. In 1715 she suffered a stroke which left her partially paralyzed and affected her ability to work. She died two years later in 1717 and was listed in a local registry as a pauper.
While Maria's sex and lack of formal education resulted in her work largely fading into obscurity for many centuries after her death, she was rediscovered in the twentieth century, and today we properly recognize her significant contributions to science and how art enabled her to reveal new truths about the natural world.

Several centuries after Maria's lifetime, entomologist Robert E. Silberglied was making his own discoveries about butterflies using another artistic medium: photography.
Silberglied's work was chiefly focused on Lepidoptera, and he was especially interested in insect vision, ultraviolet reflectance in butterflies, and courtship, mating and reproductive behavior. As a previous post by Emily Hunter describes, photography was an integral part of Silberglied's investigations into these topics. He used photographs to capture transient butterfly behaviors such as courtship displays, which allowed him to study the activities in more detail. But perhaps more revolutionary than this, he used photography to "see what a butterfly sees."

Maria Sibylla Merian and Robert E. Silberglied used art to capture important data and discover new truths about insect behavior and life cycles. These two incredible individuals illustrate the powerfully impactful intersection between art and science and demonstrate how the convergence of distinct disciplines can open new doors, overturn false notions, and excite a whole new era of scientific discovery.
