John Bennet Hearsey

Lieutenant-General Sir John Bennet Hearsey KCB FLS (21 January 1793 – 23 October 1865) was a British military officer who was colonel of the 21st Hussars and of the 3rd Bengal Light Cavalry.

He and another Indian sepoy—who had refused to arrest Pandey—were later hanged, despite Pandey's pleas that he had been under the influence of opium and bhang at the time of his actions.

[5] Prophalangopsis obscura, a winged insect species found North India, was identified in 1865 by Francis Walker from Hearsey's specimen.

[9] His collection was a significant source for John O. Westwood's illustrated book Cabinet of Oriental Entomology; Being a Selection of Some of the Rarer and More Beautiful Species of Insects, Natives of India and the Adjacent Islands (1848).

[10] Hearsey's entomological and botanical diary (1838–46) is held at the Oxford University Museum of Natural History.
