Brownheaded Ash Sawfly (BHAS) Update

—Dr. Robert Bauernfeind

While I had not intended to follow the progress of BHAS as I have done in previous years, I can’t seem to drive past the “busy beavers” without stopping to have a look. And so, within the past week, pinhole feeding has progressed to the tattered-appearance phase. Like ETC and EPS, BHAS activities are about a week ahead of where they were in 2014.
