Ophiocordyceps is a genus of parasitic fungi known for infecting insects, particularly ants. These fungi manipulate the behavior of their hosts, causing them to climb vegetation before dying. Once the host is in an ideal location, the fungus grows and releases spores to infect other insects. This unique life cycle has made Ophiocordyceps a subject of scientific interest, especially in studying parasitism and ecological interactions. Some species, like Ophiocordyceps sinensis, are also valued in traditional medicine and are researched for potential health benefits.
