Tillyard specialised in the phylogeny and classification of freshwater insects such as caddisflies, dragonflies, mayflies and stoneflies. Published many studies. Tillyard spent his entire entomological career living in New Zealand and Australia, and most of his work on the Elmo fossils was done with specimens collected by the Yale Peabody Museum and shipped to him in New Zealand. But he also took a number of trips to London and Europe, travelling by steamship to the west coast of the United States, then across the country by rail, and by steamship again from the east coast of the U.S.A. to London, then back by the same route.[https://doi.org/10.2317/0022-8567-85.4.353]
