Technology for most invertebrates is limited by their relatively small size; but our 0.2g tags now make tracking of many more species possible. Local movements of the small species are still best served by traditional VHF beeper tags. However, if trying to record the migration of insects past a migration point, or if recording presence/absence (visits to a colony or time that pests spend in a crop) then Coded VHF tags can help prevent missing events. For more information about the advantages of Coded VHF, please see "Coded Tags or Beeper Tags?" on our FAQ page.
