Re: [beemonitoring] PA/NJ Lithurgus chrysurus update.
I can add negative results from 4 sites in Berks County and one in Pike County. The Berks County blooms were also near railroad lines, but the one in Pike County was on a section of I-84. Blooms at two ramps plus a section nearby with safety fencing.
A lot of bumble bees (not yet identified) and a few honey bees, but nothing at all like Lithurgus.
