Bombay Hook National Wildlife Refuge

This is a summary of bee data from 4 fields from Bombay Hook National Wildlife Refuge, Delaware collected in August 2008. Each field was sampled with 5 fluorescent yellow, 5 fluorescent blue, and 5 white 3.25 ounce bowl traps.

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 a brief site description followed by a table of results.

A set of high quality bee fields. Note that there are 3 species of Melissodes present along with one of their uncommon nest parasites (Triepeolus cressonii). Again we have the refuge bee Ptilothrix bombiformis here on the refuge, reflecting the native mallows in the brackish and fresh water portions of the marshes. Number of individuals and species totals fall within what would be expected from the region.
