Why is this scientist famous?

Maria Sibylla Merian was a naturalist and artist who raised and observed insects, recording their life cycles and relationships with plants. Her illustrated books, especially her work on Suriname, helped readers see insects as living organisms with connected stages of development.

Merian combined repeated observation, specimen rearing and detailed illustration. Her plates documented relationships among insects, food plants and habitats, linking careful pictures to natural-history evidence. Her work is also a reminder that European science in the colonial era depended on knowledge and labour from Indigenous people and enslaved communities.

Maria's story

Learning to draw and observe

Maria Sibylla Merian was born in Frankfurt in 1647 into a family connected with printing and publishing. After her father died, her mother married the artist Jacob Marrel, in whose workshop Merian learned painting, watercolour and copperplate techniques. By her early teens she was collecting caterpillars and watching them change. Rather than relying on stories that insects appeared spontaneously from mud or decay, she reared specimens and recorded what emerged from them.

Caterpillars as a subject of study

Merian’s early books brought together drawings and descriptions of caterpillars, pupae, moths, butterflies and their food plants. She observed that different caterpillars produced different adult insects, and that the insects fed on particular plants. Some pupae produced parasitic wasps or flies rather than the butterfly she expected, an observation she described as a “false change.” Her books made the sequence from egg or larva to adult visible to readers through repeated, carefully arranged studies.

A scientific journey to Suriname

In 1699, aged 52, Merian travelled to the Dutch colony of Suriname with her younger daughter Dorothea. She wanted to observe tropical insects and plants where they lived, rather than study only specimens brought back to Europe. The journey was difficult; after illness, the pair returned to Amsterdam in 1701. Merian’s field notes and watercolours became the basis of her best-known book, Metamorphosis Insectorum Surinamensium, published in 1705.

Pictures that showed relationships

The book contained large hand-coloured engravings of insects alongside the plants and settings associated with them. One plate could show a plant, feeding insect and different stages in a life cycle together. This arrangement was visually striking but also informative: readers could see that insects were connected to particular foods and habitats. Her observations were not all correct by modern standards, but much of her work was unusually careful and many details were later confirmed.

Collaboration and colonial context

Merian’s Suriname research depended in part on knowledge and labour from Indigenous people and enslaved people living in the colony, who collected specimens and helped identify them. The Rijksmuseum notes that Merian also recorded the mistreatment of enslaved people by the Dutch. Her work should therefore be understood both as a major contribution to natural history and as research made possible within a colonial society. Her books were admired by European collectors, and the Russian tsar Peter the Great’s family acquired several volumes in 1716–1717, just before and after her death. The images remain valuable as both scientific records and works of art.

What did they discover?

Insect life-cycle observation

Raised caterpillars and other insects to document their transformations rather than relying only on preserved specimens or inherited accounts.

Host-plant recording

Connected insects with the plants they fed on and the habitats where they were found.

Suriname natural history

Recorded insects, plants and other animals during the 1699–1701 expedition, later publishing the observations in a major illustrated book.

Scientific illustration

Combined accurate observation with watercolour, engraving and hand-coloured printing to communicate natural history to readers.

Observation of parasitism

Recorded cases where pupae produced wasps or flies instead of the expected butterfly or moth, an early account of insect parasitism.

Amazing facts

01

Merian began observing caterpillars as a teenager and later described how she collected and reared them to find out what adult insects emerged.

02

She learned watercolour and copperplate techniques in her stepfather Jacob Marrel’s art workshop.

03

Her book Metamorphosis Insectorum Surinamensium was published in 1705 and contained 60 hand-coloured engravings.

04

The book’s images often placed an insect’s life stages together with the plant it used for food or habitat, a visual way of showing ecological relationships.

05

Merian and her daughter made the journey to Suriname in 1699, when Merian was 52; the trip was unusually independent for a European woman of her period.

06

The expedition ended early after illness, and they returned to Amsterdam in 1701.

07

Merian recorded “false changes” when a pupa produced parasitic flies or wasps instead of the butterfly or moth she expected.

08

The Rijksmuseum records that Indigenous and enslaved people in Suriname collected specimens and helped her identify and name them.

09

Merian’s book could be bought with its accompanying text in either Dutch or Latin.
