[5] Flohr retired from day-to-day banking in 1877 and devoted himself to the study of insects, especially beetles.

Interest in comparative anatomy remained high following the publication of Darwin's On the Origin of Species, and Flohr's field work was cited extensively in the Biologia Centrali-Americana encyclopedia.

[3][4] Between 1878 and 1885, British naturalist Henry Walter Bates named several species of North American beetle for Flohr, including

Cope wrote:I am indebted to my excellent friend, Dr. Julius Flohr, of the city of Mexico, for a canoe excursion on the lake Xochimilco [...] Here I had an opportunity of seeing the botany and zoology of the very irregular shores, which are so curiously constructed by the art of the natives [...] The ends and shores of the piers are the resting place of innumerable snakes, which can be readily observed from a canoe.
