The maps and tables of periodical cicada emergence are limited to the main emergence of the broods and do not reflect these spurious broods regardless of their size. These individuals are often referred to as stragglers.

These are small groups of individuals emerging 1 or more years early or late. While periodical cicada broods are predictable and can be forecast decades into the future, there is a bit of uncertainty with a relatively small number of periodical cicadas emerging in off years. Emergence of Kentucky Periodic Cicada Broods through the Year 2033 Encounters with periodical cicadas can be unnerving to some but these insects cannot sting and do not harm humans, livestock, and pets. These clumsy fliers often stay in the upper canopy of trees while they are active from late April thru June. Periodical cicadas have black bodies, red eyes, and red-orange wing veins in two pairs of clear wings that are held roof-like over the abdomen. Songs of the different species are distinctive and include calling and courtship sounds. Males fly to high, sunlit branches and sing together in choruses that attract females. They are produced by males using specialized structures on the abdomen. The emergence of millions of these insects in an area provides a striking visual image and the sounds they produce can be deafening. Representatives of both occur in the Commonwealth. Spectacular broods of periodical cicadas, designated by Roman numerals, emerge at predictable intervals (13- or 17-years) across the eastern US.

Adult cicadas do not feed on leaves, and may suck juices from tender twigs. Habitat, Food Source(s), Damage: Male cicadas rest on tree trunks and branches and “sing” to attract females, producing a periodic whine by means of two special vibrating membranes in the sides of the abdomen.

Adult cicadas emerge from this last nymphal stage through a crack along the back, leaving the light brown cast skin behind. The nymphs climb onto tree trunks, low plants or other objects. Under some conditions, the exit hole is associated with a mud cone or chimney 3 to 4 inches high. Fully developed nymphs burrow out of the ground at night, leaving a 1/2-inch hole behind them. As they molt through several growth stages (instars), they may burrow several feet down. They burrow into the soil, seeking tree roots. In 6 to 7 weeks, small nymphs hatch from the eggs and drop to the ground. Female cicadas insert clusters of eggs into the twigs and small branches using a saw-like egg laying structure (ovipositor). Life Cycle: The common dog-day cicadas (sometimes called the annual cicadas or locusts) appear in late summer and have life cycles of 2 to 5 years. Adults emerge from April through July, depending upon species and locality. The periodical cicada species that do occur in Texas complete their life cycles in 13 years, although some emerge almost every year. The smaller periodical cicada, Magicicada septendecim (Linnaeus), completes its life cycle in 17 years, and emerges in large numbers (broods) in large geographical areas. Nymphs resemble wingless adults, are brown and have strong front legs well developed for tunneling in the soil. The larger species are about 1-5/8 inch long and 1/2-inch wide with brown or green, black and white body markings. All have prominent bulging eyes and semi-transparent wings held roof-like over their large bodies. Photo by Drees.ĭescription: Adults vary in size and color according to species.
