What is "hermarchus"

Hermarchus or Hermarch (, "reign of Hermes"; c. 325-c. 250 BC), sometimes incorrectly written Hermachus , was an Epicurean philosopher. He was the disciple and successor of Epicurus as head of the school. None of his writings survive. He wrote works directed against Plato, Aristotle, and Empedocles. A fragment from his Against Empedocles, preserved by Porphyry, discusses the need for law in society. His views on the nature of the gods are quoted by Philodemus.

Hermarchus is a genus of very large stick insects within the order Phasmatodea and the tribe of Pharnaciini. Females are often 200 to 240 mm long (body length), depending on species. There are 14 known species, which occur in Papua New Guinea, Fiji, Australia, Philippines and New Caledonia. The males are winged, while wings are lacking in the larger females. They feed upon the leaves of plants such as eucalyptus, guava, bramble and acacia.
