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. •

Hybothecus flohri In 1884, Flohr accompanied American zoologist
Edward Drinker Cope in Mexico. 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. The wife of our Indian boatman was particularly acute in detecting these animals before either my friend or myself could see them. == Death ==
