Darwin met Leonard Jenyns whilst studying here at Christ's College. Although Blomefield was older than Darwin by about ten years, the two of them shared a common interest in natural history – Blomefield later described Darwin as “a most zealous Entomologist” – and thus they became great friends. After graduating, Jenyns became vicar of Swaffham Bulbeck, and Darwin continued to visit him, as Jenyns recalls in his autobiography:
“...we made Entomological excursions together, sometimes in the Fens—that rich district yielding so many rare species of insects and plants—at other times in the woods and plantations of Bottisham Hall. He mostly used a sweeping net, with which he made a number of successful captures I had never made myself, though a constant resident in the neighbourhood.”(Blomefield, Leonard Jenyns : Chapters in my life : Bath, 1887)
