Method Notes:
11/06/14: The revised 2014 Cerceris Wasp Survey Protocol is available in the References section below. In addition, a 2014 version of the Cerceris Letter has been posted as well. Please use these documents in future surveys.

04/17/14: For the 2014 survey season and beyond, for Cerceris surveys, you will now need to ensure that the appropriate host species (Ash for Agrilus planipennis and Oak for the other three Agrilus targets) is within a 200 meter (650 foot) radius of the sampling site.

02/27/13: When reporting data into NAPIS, use the NAPIS code 00581 - Trap;Prism;Purple (No Lure). By using this code for A. biguttatus, you are stating that you have conducted both a visual survey (as described above) and have used a purple prism trap.
