Odo Reuter

Odo Morannal Reuter (28 April 1850 – 2 September 1913) was a Swedo-Finnish zoologist and poet. He was a specialist on the heteropteran bugs.

Early life
Reuter was born in Åbo on 28 April 1850, and died there on 2 September 1913. Reuter became a student at the University of Helsinki in 1867. He gained his master's degree in philology in 1873, followed by a doctorate in zoology in 1877, when he became an associate professor of zoology.

Career
Reuter was a hemipterist, a specialist in mirid plant bugs, becoming the world's leading expert in this group at his time. He coined the term "parasitoid" to describe the way of life of species such as many wasps which feed on but do not immediately kill their prey. He published nearly 445 papers by 1907 most dealing with the Hemiptera.

In addition to systematics, he took an interest in movement and nutrition in insects. He also wrote popular natural science works for the general public.

He was dismissed from his position in 1910 due to prolonged leave on account of illness. He formally retired in 1910 due to long-term health problems. His enthusiasm remained, and in 1911, despite his blindness, he published Nattens sånger (Night's Songs) describing the experiences of his latter years. He died on 2 September 1913 in Turku.

Works
Reuter's many publications on entomology include:

He also wrote literary criticism, travel guides and poetry. His last works were produced when he was blind.
