A regular species that might be seen on almost any day during the spring, summer, and fall, this species appears to be most common in spring from May 20th-June 1st and from June 25th-July 10th during the summer. It is annual during the fall; however, sightings are not regular with records distributed evenly from mid-August to mid-October. The highest concentration of records is in the final week of August, though there is little displayed pattern. Many sightings are in conjunction with large storms, especially in late summer and fall, which are unpredictable as to timing.
