Yes, there is a difference between a cicada and a locust. Cicadas and locusts are in fact different insects. They aren't even from the same order. Locusts swarm, and periodic cicadas are often thought to swarm.
Is there a difference between a locust and a grasshopper?
Locusts and grasshoppers are the same in appearance, but locusts can exist in two different behavioural states (solitary and gregarious), whereas most grasshoppers do not. When the population density is low, locusts behave as individuals, much like grasshoppers.
Is a locust and a grasshopper the same thing?
Locusts are certain species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious.
Technically cicadas don't bite or sting; they do however pierce and suck. They might try to pierce and suck you, but don't worry, they aren't Vampires nor are they malicious or angry — they're just ignorant and think you're a tree. Just remove the cicada from your person, and go about your business.
The cicadas will have four-to-six weeks to mate and lay eggs before they die. For the next several weeks, their mating calls will be quite loud. In July, however, it gets quite bleak for the bugs. They all die.
When the branches die and leaves turn brown, it is called flagging. Once the cicada hatches from the egg it will begin to feed on the tree fluids. After the long 2 to 17 years, cicadas emerge from the ground as nymphs. Nymphs climb the nearest available tree, and begin to shed their nymph exoskeleton.
Despite what you might have heard, cicadas are not blind. Their red eyes see fine. They do not bite, although, if very thirsty, one may probe you a bit with its tiny beak in search of moisture. Periodical cicadas are not one species.
The many cicada species all have one thing in common. Their lifespan above ground is much shorter than their underground lives. Depending on the species, a cicada might emerge as often as annually or as infrequently as every 17 years, but they expire approximately five to six weeks later.
The seven periodical cicada species are so named because, in any one location, all of the members of the population are developmentally synchronized—they emerge as adults all at once in the same year. This periodicity is especially remarkable because their lifecycles are so long—13 or 17 years.
The cicada's purpose in terms of critters: Cicadas provide a link in the food chain between trees and critters, which I'll define as any animal that will eat a cicada. Critters love cicadas, and a 17 year cicada emergence is the single greatest feast of their lives.
Periodical cicadas are found only in the United States east of the Great Plains. The 17-year cicadas are found mainly in the northern, eastern, and western part of their range. The 13-year cicadas predominate in the South.
The cicada isn't as bad as its reputation. David Rothenberg, in his book, quotes a 1936 article from The New York Times that reminded readers "that cicadas are not locusts, they do not eat crops, they do not sting babies to death, and they will not harm your fruit flies excessively."
No, but people call them locusts, and have since the 1600's. Grasshoppers, Crickets and Katydids are often confused with cicadas because they are relatively large, singing insects. There are many differences between cicadas and Orthopterans, but the easiest way to tell them apart is Orthopterans have huge hind legs.
If you're used to hearing cicadas sing at night, you may be interested to know that these creatures actually qualify as one of the loudest insects to be found anywhere in the world. Cicadas make their clicking and chirping noises quite intentionally, and they serve a very specific purpose. The songs are a mating call.
People, pets, rodents, marsupials, reptiles, birds, fish, insects, arachnids — virtually any creature will eat them. Some insects are known for specifically preying on cicadas, for example, Cicada Killer Wasps are well known for capturing cicadas for their larvae to eat them.
Cicadas make a variety of sounds, including very loud buzzing sounds. The males have tymbal organs that include rib-like bands on a membrane that can be vibrated very rapidly by a special muscle. The sounds include courtship calls and squawking sounds when the cicada is handled or disturbed.
Cicada 3301 is a nickname given to an organization that on three occasions has posted a set of puzzles to possibly recruit codebreakers/linguists from the public. The first internet puzzle started on January 4, 2012, and ran for approximately one month.
2004 is the year of Brood X—a group of cicadas that emerge from the soil every 17 years to molt and mate. Other types come out every 13 years. This prompted one listener from Washington, D.C., to wonder why these insects have such odd-numbered life cycles.
The cause for all that chirping is nature's oldest, Hughes said. Cicada males make sounds to attract nearby females, who respond by snapping their wings. The male hears this and responds to by moving closer.
Cicadas “eat” / drink something called xylem (sap), which is a watery tree fluid containing amino acids and minerals. Cicadas drink rather than eat. People probably ask “what do cicadas eat” because they are afraid that cicadas will eat their flowers and garden fruits and vegetables.
Towards the eastern coast, in sub-tropical, sub-humid and temperate environments, cicadas are conspicuous in open forests and woodlands. Like the acacias of the west, eucalypts support a high diversity of cicadas in the east. Most of these habitats support 15 to 25 species at any given location.
The adult insect, known as an imago, is 2 to 5 centimetres (1–2 in) in total length in most species, although the largest, the empress cicada (Megapomponia imperatoria), has a head-body length of about 7 centimetres (2.8 in), and its wingspan is 18 to 20 centimetres (7–8 in).
