![]() ![]() A Cicada is much more similar to an aphid, and a locust is a short-horned grasshopper. ![]() The following are some of the ,major differences between a cicada and a locust. Most damage occurs when too many eggs are laid on the branches, resulting in problems for the young trees. However, the risk of plants and trees being destroyed is very small. Although there is a large number of periodical cicadas this may be a bit threatening. The adults can come out from the ground on schedule, mainly in the month of May and June but annual cicadas, emerge from the ground every year in the latter parts of the warm season. Also these cicadas come out every 13 to 17 years. There are various types of species of periodical cicadas that emerge at different times. The insects mature underground at depths of to 2 feet or more. Periodical cicadas come out only at a given time. Periodical cicadas are also typically black or dark in colour. They have wings that can be easily identifiable because the membranes running through them are clear. They have stout bodies and their eyes are large, even too large for their big heads. The mouths of cicada are designed to suck juices from the plant for sustenance. Cicada mouths are designed to eats plants. The females lay their eggs in woody twigs before they die after mating.Īll types of cicadas are members of the Homoptera order of insects. However, the male cicadas sing, and produce a high pitched, droning sound, that attracts the silent female partners. Emerging cicada nymphs can shed their outer skins and spend their adult lives to mating. Periodical cicada nymphs can stay below the ground surface for up to 17 years before they can emerge in great numbers and climb up trees and other vegetation. Annual cicada nymphs can live for one or three years underground, surviving on the juices of plant roots. The eggs hatch, and nymphs, or immature cicadas, show up and burrow into the ground. Immature cicadas spend a lot of their time in the ground before they can emerge for a brief life as an adult. Despite their differences in appearance, periodical cicadas are normally called 17-year locusts. All of their legs are about the same length unlike those of locusts and grasshoppers. Cicadas, just like locusts and grasshoppers, have three pairs of legs. Periodical cicadas have red eyes, and annual cicadas have dark eyes. Periodical cicadas, however, are usually smaller than annual cicadas. Both these cicadas are dark, stout insects with very large heads and transparent wings. There are two types of cicadas, which are the annual cicadas that belong to many insect species, and the periodical cicadas. The two insects share some similarities, plus the names have been improperly used interchangeably for a long time. The colonists assumed that large clouds of insects emerging from the ground periodically were swarms of destructive locusts. Since the periodical cicadas can only be found in North America, the colonists did not know how to classify the insects. ![]() The confusion between cicadas and locusts can be traced back to the early colonists. ![]()
