This will translate this blog to speech.

A blog that will gradually post the results of a study of the bees found by refuge biologists and volunteers using bee bowls traps on USFWS Region 5 National Wildlife Refuges in the Northeastern United States.

Parker River NWR

This is a summary of data from 6 fields from the Parker River NWR Complex during late August 2008.

A complete table of the data is available from Leo Shapiro (lshapiro@umd.edu), Sam Droege (sdroege@usgs.gov), or the refuge biologist.

Below is a table of the site numbers and the brief site description.

Interpretation of the results: The bees here indicate a classic dune/deep sand site. There are two species that rarely occur outside of deep sand areas: A. splendens, and L vierecki and there are several species that are restricted to dune sites such as L. marinum and L. JG_3. L. marinum is a well known species that occurs in dune sites along the Atlantic and Gulf Coast seaboards.

collection localities



L. JG_3 is an undescribed species that Jason Gibbs at York University discovered hiding among specimens we had collected from the end of Long Island and at Chincoteague NWR. Only 4 or so specimens were known before so this is a significant addition to what is known about that species (and a state record) and we have sent several specimens to Jason for DNA extraction.

The other species found at this site are around regionally, but some, such as L. pilosum, H. leavitti, and M. brevis tend toward drier sites. Heriades leavitti is potentially a state record too and we have also found them on Assateague Island, but the females are difficult to ID and there is controversy about it possibly be the same as H. variolosus so we will likely send it off too for DNA barcoding. So, the fields in this refuge represent some high quality dune habitats that are nice to see.
