Frank H. Hennemann (born 1 July 1978 in Ludwigshafen) is a German entomologist and taxonomist who works in the field of biodiversity research on the systematics and biogeography of stick insects (Phasmatodea).

In 1990, for example, he acquired additional species of stick insects at a meeting of phasmid friends at the Palatinate Museum of Natural History in Bad Dürkheim, so that he soon had an entire room full of breeding cages and terrariums.

From 2001 onwards, with his long-time friend Oskar V. Conle, he undertook collecting trips and expeditions to Brazil, Peru, Ecuador, French Guiana, Costa Rica and Panama, as well as to Texas, to obtain stick insects for biodiversity studies and to observe them in their habitats.

One of these trips was a multi-week expedition to the biological research station Panguana in the lowland rainforest of Peru in 2004, in which he took part together with employees of the Bavarian State Collection of Zoology.

[10][11] Among the stick insects he discovered or described, there are several species that are very common among breeders in Europe, such as Peruphasma schultei from Peru, Myronides glaucus from Peleng, Oreophoetes topoense from Ecuador, Haaniella gorochovi from Vietnam, and the walking leaves Phyllium philippinicum and Phyllium ericoriai from the Philippines or the Obriminae Trachyaretaon bresseeli, Sungaya aeta and Sungaya ibaloi, which also come from there.
