The state of Missouri is on the verge of a major periodical cicada emergence.
Periodical cicadas emerge earlier and are different from the more familiar dog-day cicada, which come out later in the Summer. The periodical cicadas have dark bodies and reddish eyes and wings, and are smaller, while dog-day cicadas range from brown to green with black and white markings. When a brood emerges, as many as a million noisy male cicadas can gather in trees over a single acre and join in a piercing chorus of mating calls. Though the roar produced by these cicadas is powerful enough to drown out lawnmowers and chainsaws, Joe Jerek, spokesperson for the Missouri Department of Conservation, says the cicadas don't pose any real threat. The cicada chorus is likely to begin tuning up early next month, and taper off in June. The Missouri Department of Conservation does not recommend the usage of pesticides to keep the cicadas off of small trees, though light mosquito nets or mesh, no thicker than a quarter of an inch, can be effective.
