    From all over the Southwest, the surveys seem to point generally to the presence of Common Green Darners and the absence of Variegated Meadowhawks at this time

      Based on general observations and no good survey data in central New Mexico, it does seem that the Variegated Meadowhawks have a burst of breeding activity

        Based on general observations and no good survey data in central New Mexico, it does seem that the Variegated Meadowhawks have a burst of breeding activity early in the season (April-May), then become scarcer during mid-summer, then another upswing in late summer and fall (August or Sep to Oct). It seems when I see the most skimmers at ponds in June-July, I see the fewest VMs (but maybe my observations are biased). Are VMs deterred by very high temperatures? Or is there a within-season breeding cycle accounting for radical changes in numbers of adults?
         
         
        Thanks,
        Jim
