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.

Erie National Wildlife Refuge

This is a summary of bee data from 5 sampling locations from Erie National Wildlife Refuge 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.

Note that field 5601 was a trial run and not part of the collection of the other 4 fields. Interestingly, this field has a bit of a different bee fauna than the cluster of sites for the main study, having a couple of the Eucerine species (P. pruinosa, and M. druriella) that did not show up in the other fields as well as 5 additional species that either did not show up at all in the other surveys or were at much lower numbers. So, your neighborhood appears to count when you are a bee.

Overall, a not unexpected group of bees from northwestern Pennslyvania. The one exceptional species is L. albipenne which is an uncommon and rarely seen sweat bee. Not much is know about it other than it seems to show up here and there. Numbers of bees are rather low compared to some of the other refuges, but, as always, there are always bees present.

Sam and Leo

To make a prairie it takes a clover

and one bee,--

One clover, and a bee,

And revery.

The revery alone will do

If bees are few.
