Pic's from an auletes site here in NC!

We collected hundreds of casts from oaks and filled containers with molts picked up from the ground.

We also collected Sunday the 26th ~8:00 pm & again Monday evening the 27th; the numbers of auletes were unbelievable.

Although auletes is a very common cicada locally - and across the South, I have never seen anything like the density and activity for auletes here off Lake Wheeler Rd.

Sunday evening, we arrived a little before 8:00 pm and the chorus was ear blasting. We managed to catch only 2 with an extension net. The following evening, my assistant, Evie, and I left the museum around 5:00pm and arrived shortly after. She and I collected shells, dead specimens, and scanned the trees for adults, but we couldn't see nor did we hear any among the branches. Approx. 7:30pm, Evie and I heard the occasional flutter of wings, squawk of a male and spotted a few move from tree to tree. There was an occasional random short burst as though a male was gearing up to call, but then would fall silent ... seemed a bit strange. Most impressive was what followed! As the last rays of sun shone through the upper most branches several steady buzzes began to be heard...then at 7:47 pm on Monday, 27 August - as the sun slipped below the horizon - a single male auletes started to call from an old growth post oak - within fractions of a second - the roar of ensuing calls moved from tree to tree in a wave. I have observed this phenom among taxa within the pruinosus group, but never in auletes. Then again, I have never seen auletes in these densities! I managed to collect 5 specimens in 18 minutes of available light ... after which we could no longer pinpoint them in the dark - made collecting impossible; however, the males continued to call 30 to 40 minutes more - well after dark.
