I wasn't confident that we'd see an emergence as far north as Champaign, so I was excited when my father-in-law reported the Brood XIX cicadas had crawled up from the soil around Lake Sara in Effingham. When we arrived for a family holiday this past weekend, the first thing we noticed was the constant drone of the cicadas in the towering oaks. Much lower in tone and less modulating than the annual cicada, the singing of the Brood XIX cicadas is almost pleasant to experience. Throughout the weekend, we tried to discover a fitting description for their song. Some thought it sounded like the song of frogs; others found it reminiscent of water running through a narrow pipe. At times, it sounded like low-budget sound effects from a B-rate monster movie.
During both days we were at the lake, I took time to walk through the woods and along the shore to photograph these amazing creatures.
After spending a couple of days marveling at these insects, whose appearance is simultaneously magestic and alien, I keep coming back to the unusual nature of their life cycle. I wonder what evolutionary advantage is provided by feeding below the surface for so long, only to emerge as teenagers for a few short weeks of mating and egg laying. Come to think of it, maybe it's not all that different than Spring Break in Daytona Beach.
