Calvert County (MD) Dragonflies and Damselflies: Part Three - Richard Orr & the Maryland Biodiversity Project Database

In researching dragonflies I came across a Maryland database that tracks species according to occurrence in each of the counties. Richard Orr has created a database of county records for dragonflies and damselflies in Maryland and Washington DC (see www.marylandinsects.com). He updates the database regularly and the records are also reflected in the Maryland Biodiversity Project (www.marylandbiodiversity.com). His county records are also incorporated for the Maryland Eastern Shore counties in Appendix 4&5 of the book “Natural History of DelMarVa Dragonflies and Damselflies” by Hal White. The iNaturalist database has a long way to go to catch up with county records that are consistent with Richard Orr’s records. The outstanding feature of the iNaturalist database (besides the incredible ID tools) is the ability to access individual observations that include specific locations and timepoints, invaluable aids for those wanting to observe firsthand a particular species. As more entries are made into the iNaturalist program, eventually the various databases will be consistent with one another. Until the start of D&D season is upon us in April (maybe March?), I hope to spend some time examining the occurrence of the various species in the southern Maryland counties of Calvert, Charles, and St. Marys as reflected in the databases and incorporate some of that information in upcoming posts. Once the dragonflies and damselflies emerge, hopefully I will be out photographing and adding my observations to the iNaturalist database.
