The Arthropods Division is active in the Biodiversity research (Biogeography and Ecology, Phylogeny and Phylogeography) of the ground/soil and saproxylic groups of Coleoptera (Carabidae, Tenebrionidae, Cerambycidae, Scarabaeoidea, Buprestidae, etc.), Orthoptera, Coleoptera of Forensic interest (Histeridae, Dermestidae, Silphidae, κλπ.), Scorpions and Pseudoscorpions, ground Spiders (Gnaphosidae, etc.), Harvestmen, as well as Centipedes/Millipedes. Specimens from Crete and the southern Aegean (± 60%), mainland Greece (± 30%) and eastern Mediterranean countries comprise the main part in the above collections (> 2.5 million specimens).
The Arthropod Division also maintains Type material (± 200 Holotypes & Paratypes), complete collections and voucher specimens of isopods, ants, springtails, amphipods, diptera, lepidoptera and other groups of Arthropods that do not fall in the current research of the department. These collections are the subject of donations by various researchers or amateurs to the Museum, products of revisions of a Taxon or Fauna in the context of taxonomic dissertations that have been completed in the Museum, products of collaboration with scientific institutions that do not maintain collections, etc.
As a University Museum, taxonomic/biogeographical/phylogenetic research in the Arthropod Division is largely based on the academic contribution of undergraduate and postgraduate students, as well as PhD candidates completing their dissertation in one of the offered courses. The contribution of citizen scientists is also welcomed. Respectively, postdoctoral fellowships and other researchers from Greek or international institutions, cooperate with the department if their taxa of interest are available in the collections.
Arthropod collections include wet (70-96% alcohol) and dry specimens of most of the Insect orders, Isopods, Myriapods and Spiders of Greece and the Eastern Mediterranean. The total number of specimens today exceeds 2.5 million, while digital cataloguing* of most of the groups (except Coleoptera and Spiders) has been completed. Indicatively, Orthoptera (wet + dry) exceed 50,000 registered specimens, Myriapoda > 63,000, Opiliones > 16,000, Isopoda > 38,000, etc., according to the January 2022 census.
*All catalogued specimens include complete sampling data (location, date, numbers of individuals, researcher who collected them and/or identified them, etc.), divided into Classes, Families and/or Species, depending on the group and the availability of taxonomists. All entries are databased, so taxa of interest are traceable via simple procedures (PC).
