He wrote 45 scientific papers on Microlepidoptera and, later Diptera and described several new species including Coleophora glaucicolella, Coleophora sylvaticella and Stigmella confusella . The description of Stigmella confusella was a collaboration with his friend Thomas de Grey, 6th Baron Walsingham.
