Image from The Chironomidae, or midges, of Illinois, with particular reference to the species occurring in the Illinois River by John Russell Malloch. John Russell Malloch (16 November 1875 – 1963) was a Scottish entomologist who specialised in Diptera and Hymenoptera.

Malloch was born at Milton of Campsie in Stirlingshire, Scotland. His widowed father had one son, James Malloch (born 1873) when he married John Russell's mother, Margaret Stirling, on 30 August 1875. He and several others of his family worked at a textile factory in the area, but he spent his spare time collecting insects in the fields. Malloch later described his Scottish household as "a moderate sized Scotch family of eight, three sisters and five brothers." In 1917, he published a seminal study listing and providing detailed categorization of the known Diptera order.
