Neotibicen

Cicadas of the genus Neotibicen are large-bodied insects of the family Cicadidae that appear in summer or early fall in eastern North America and formerly Bermuda.^[1] Common names include cicada, harvestfly, jar fly,^[2] and the misnomer locust.^[3]

Taxonomy

In 2015, these species were moved from the genus Tibicen (now genus Lyristes Horvath, 1926),^[4] which was redefined in the twenty-first century to include only a few European species, while species from the Western United States and Mexico are now placed in a separate genus, Hadoa.^[5] In addition, several former Neotibicen species have been moved to the genus Megatibicen.^[6][7]

Description

Neotibicen cicadas are 1–2 inches (25–51 mm) long, with characteristic green, brown, and black markings on the top of the thorax, and tented, membranous wings extending past the abdomen.^{[citation needed]} The fore wings are about twice the length of the hindwings. Adults feed using their beak to tap into the xylem of plants; nymphs feed from the xylem of roots.^[8]

Neotibicen species are the most commonly encountered cicadas in the eastern United States. Unlike periodical cicadas, whose appearances aboveground occur at 13- or 17-year intervals, Neotibicen species can be seen every year, hence their nickname "annual cicadas". Despite their annual appearances, Neotibicen probably take multiple years to develop underground, because all cicada species for which life cycle lengths have been measured do so, except when growing as agricultural pests.^[9] Their annual reappearance is presumably due to overlapping generations.

Communication

Like other members of the subfamily Cicadinae, Neotibicen species have loud, complex songs, even (in many cases) with distinct song phrases.^[10]

Males produce loud calls in the afternoon or evening (depending on the species) to attract females. These sounds, distinctive for each species,^[11] are produced by specialized tymbal organs on the abdomen as in most cicadas. These calls range from a loud buzz to a long rattling sound, sometimes with a pulsating quality.^[11]

Predators

Many animals feed on cicadas, which usually occurs during the final days when they become easy prey near the ground. One of the more notable predators is the cicada killer, a large wasp that catches the dog-day cicada. After catching and stinging the insect to paralyze it, the cicada killer carries it back to its hole and drags it underground to a chamber where it lays its eggs in the paralyzed cicada. When the eggs hatch, the wasp larvae feed on the paralyzed, but still living, cicada.
