Attached is a file showing all the state of Maryland county records for bee species I have vetted to date. This is not, by any means a complete list, as there are many museums and publications with Maryland records yet to be investigated as well as jars of specimens from several projects by other researchers I have yet to sort. However, the list is maturing and general patterns of rareness and commonness are now apparent at the level of the state. Feel free to use these data, but be aware that almost all counties “should” have more than 200 species in them. Clearly there is much field work to do compared to the well-organized affinity groups for birds, herps, Odonates, and butterflies in the diverse state of Maryland.
I am indebted to the many collectors, investigators, and photographers who have contributed their records and look forward to receiving more information from them in 2013.
The following people and institutes contributed records for 2012
Droege and Devalez
MD Department of Agriculture
Thomas of Baltimore
The species total is approximately 390 (several species need some further confirmation). There are now 2339 Records county records. The table below documents the total number of records for each county and the number that were new for 2012.
District of Columbia
There were 26 ”New” State Records
Andrena gardineri – Female - May 22 2012 – Garrett County - Sam Droege – Several specimens netted in a wet meadow - A largely southern species, it is near the northern edge of its range here; occurs throughout the southern Appalachians and the Piedmont
Bombus terricola - Female - July 8 2012 – Garrett County - Fred Paraskevoudakis – One specimen collected in a bog- A largely northern and declining species, most species to the south were collected in the Smokies
Cemolobus ipomoeae – Female - July 12 2012 – Caroline County – Steve Westre – One specimen collected in a glycol trap in a sandy open field next to the Choptank River (Thank you Mike Price for lending your field) – A very rarely collected species, a specialist on native morning glories (Ipomoeae)
Coelioxys moesta – Female – June 23 2002 – Garrett County – Maryland Department of Agriculture – One specimen collected in an Allison – Pike trap – An uncommon northern species
Epeoloides pilosula – Male – May 7 1909 – Montgomery County - W.L. McAtee – Plummer’s Island, specimen located in the National Collection at the Smithsonian – Only a handful of specimens have been collected in the last 10 years
Holcopasites heliopsis – Female – September 9 2012 – Anne Arundel County – Jelle Devalez – Netted in an old sand pit along the Patuxent River – An amazing record of a prairie nest parasite of Calliopsis species whose nearest record is from Illinois, interestingly, the host as reported by Hurd is Calliopsis nebraskensis, there are no known records of this host species in Maryland, however, there are records from northern NJ, NY, and Connecticut from what appear to be the New York City area so this species should be looked for regionally on Verbena, pictures are up on our Flickr site
Hylaeus georgicus – Male – April 15 2012 – Dorchester County – Sam Droege – Netted off of willow alongside the road – One of only a few recent records of this very rare species east of the Mississippi, pictures up on our Flickr site
Lasioglossum abanci – Female – March 16 2012 – Prince George’s County – Sam Droege- A difficult to identify species, with likely more specimens to be found as we learn to identify them
