Around 1873, Maskell became interested in
entomology and wrote a book,
An Account of the Insects Noxious to Agriculture and Plants in New Zealand, which mostly concerned pests in the
Coccoidea family. Later, as his work became more well known, he was sent insect samples from a variety of locations, including Asia,
Fiji, Hawaii and the Americas, which resulted in him proposing over 330 species names. In 1906, at the request of Dr C.L Marlett, Assistant Chief of the United States Bureau of Entomology, the collection was loaned to the Bureau for study by
Emily R. Morrison. The collection was returned to the New Zealand Department of Agriculture in 1922 and is now housed at the
New Zealand Arthropod Collection. Maskell particularly liked studying the internal
anatomy of insects, probably due to his fascination with
physiology and
microscopy, and his work was also unique in that he studied immature stages of males and females as well as the mature females. In its native Australia this pest was kept in check (so
F. S. Crawford found) by a dipterous fly
Cryptochetum iceryae which injected its eggs into the scale insect, which was then devoured by the resultant
larvae. Maskell also studied
arthropods,
protozoa and microscopic
algae, publishing more than 70 research papers on these topics. He was also a strong opponent of
Darwinism and his arguments helped to shape several scientific debates of the time. ==Death==
