We identified 4 colonies of Cerceris Wasps in close proximity to the property.  The wasp watchers have been  steadily collecting beetles (42 from all of the colonies) that the wasps have been bringing back to their nests.  The wasps become active every sunny day around 11:00 a.m. EST with their orientation flights around the nest entrance.  Very soon after leaving they start bring back beetles to their nests, where the wasp watchers are waiting to catch and release the wasp unharmed but leaving a beetle in the bottom of the insect net.  The beetles are sent to our state's coordinator for this project Claire Rutledge at the Connecticut Agricultural Experiment Station.
