Emma Sarah Hutchinson (1820–10 December 1905)[1] was a British, Victorian, lepidopterist who authored the 1879 book Entomology and Botany as Pursuits for Ladies and published in The Entomologist's Record and Journal of Variation.

She reared butterflies and moths from eggs and her work contributed to understanding of the Lepidoptera life cycle.

The summer form of the Polygonia c-album butterfly species, known as the comma, is named hutchinsoni in her honour.

Born as Emma Sarah Gill in 1820, she married Thomas Hutchinson (1815-1903[2]),[a] the vicar of the parish of Kimbolton, Herefordshire, England, in 1847 and spent most of her life there.

Hutchinson had studied the habits of the comma for 50 years and put forward the thesis that its decline in Kent was due to the burning of the hop vine after harvest, destroying the larvae and pupae.

[5] Her son Thomas (died 1916), a solicitor, was also a noted naturalist and eventually President of the Woolhope Society.
