William Miles Maskell

[6] 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.

[3] Maskell's personal collection of Coccoidea specimens which was regarded as scientifically significant and was acquired by the New Zealand Department of Agriculture.

He helped Albert Koebele of the United States Department of Agriculture collect vedalia "ladybird" beetles (Rodolia cardinalis), a predator of cottony cushion scale, which had become a devastating pest of Californian citrus farms.

[10] 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.
