Blinded Sphinx

Hi Caleb,
This is a Blinded Sphinx,
Paonias excaecatus, and we have posted numerous photos submitted in the past week from all over North America.  According to BugGuide, the Blinded Sphinx ranges over:  “all of United States and southern Canada.”  It is curious that despite varied local weather conditions, we have received reports from so many different locations this week.
