1900s: The collections were extended during the early 1900s by the acquisition of the Malcom Burr collection of Dermaptera and the work of the Imperial Institute of Entomology.
1945: Sir Boris P. Uvarov established the Anti-Locust Research Centre (ALRC) at the Museum. Between 1945-2001 many ALRC acridologists were based at the museum and their work further enhanced the collection.
1952 – 1990: During this period the Orthoptera collections were the responsibility of David R. Ragge, and were expanded by first his work on African Tettigoniidae, and then his studies of the songs of Western European Orthoptera.
1996: The ALRC, which eventually became the Natural Resources Institute, donated a large collection (over 82,000 specimens) of mainly identified material to the Museum.
A computerised catalogue of the species and type specimens in the orthopteroid collection was begun in Paradox for DOS by the Curator of Orthopteroidea at that time, Judith Marshall, and this was completed by her a few years later. From 2004 to 2008 the information in this database was carefully edited by Judith and her successor, George Beccaloni, and the taxonomy and higher classification of the species was updated.
2003: Work began to prepare the collection to be moved into a new building. Specimens from 312 store boxes and 700 sub-standard drawers were moved into new drawers with unit trays during the next few years.
2004: The current curator, George Beccaloni, transferred this database - correcting the data and updating the taxonomy and higher classification of the taxa.
2005: Collection moved from old Entomology building to temporary storage in Origins gallery, whilst old building is knocked down and a new building constructed.
2009: The collection was completely rearranged and moved into the new Darwin Centre 2 building where it is housed in compactorised metal cabinets in a climatically controlled store room.
The databased was migrated to the Museum's new collections management system, KE EMu, allowing researchers outside the Museum explore the Museum’s collection for themselves.
The termite collections index is still to be added which will be done soon after Krishna, Engel & Grimaldi's world catalogue of termites is published.
