Scientific name: Ephemera vulgata Linnaeus, 1758
Common name: Drake Mackerel Mayfly
Description: This specimen label does not directly link it to Leonard Jenyns. However, Jenyns donated much of his collection to form the Cambridge Philosophical Society museum. This material was offered to Cambridge University in 1865 and is now housed here as part of the University Museum of Zoology. Therefore, the Cambridge Phil. Soc. label means there is a high chance that this is one of Jenyns' specimens, especially as Jenyns lists this species in his notebook. The notebook entry for this species reads: 'Abundant in Spring in the neighbourhood of water. ~'
