Ludwik Franciszek Młokosiewicz (August 25, 1831 – 1909) was a Polish explorer, zoologist and botanist, who studied extensively in the Caucasus Mountains and discovered various species of plants and animals.

[1] At his father's request, from 1842 he attended the cadet corps in Brześć, however, not interested in a military career, he returned to Warsaw in 1846 and continued his education privately.

[1] At the age of twenty-two, when he had to do his compulsory military service in the Imperial Russian Army, he voluntarily joined its Caucasian Division, and in 1853 he was sent to Lagodekhi, on the south-eastern slopes of the Caucasus, in Georgia.

In 1876 after restrictions had been lifted Młokosiewicz explored the mountains of Dagestan, and two years later returned to Persia, travelling as far as Balochistan.

[4] Species that he discovered and that were named after him include the Caucasian black grouse (Tetrao mlokosiewiczi) and the golden peony (Paeonia mlokosewitschii).
