Epizoic symbioses present a form of symbiosis in which one or more species exist on the surface of an animal. As opposed to those in aqueous media, land epizoic symbioses are not well-studied and are yet to be properly systemized. The main objective of this thesis was to create a review of both published and unpublished instances of epizoic symbioses on land. Available scientific literature was perused for the purpose of cataloguing published instances while photographs on iNaturalist, Flickr and those acquired directly from authors were scrutinized in search of instances that are not published. The majority of occurrences were recorded on arthropods, with pygmy grasshoppers of the family Tetrigidae being the most common hosts. Epibionts include both photosynthetic and non-photosynthetic organisms and comprise of algae, fungi, lichens and mosses. Nearly all of the instances were documented in the tropics; humidity and water retention on the hosts' surface were recognized as significant factors in survival. DNA barcoding and metagenomics are important methods used for identification of epibionts and creation of archives of epibiont DNA sequences, respectively, which in turn allows for the examination of host-epibiont cophylogeny. Cophylogeny in conjunction with an adequate model of symbiosis provides detailed insight into complex ecology and evolution of symbiotic relationships.
