So in summary, although both locusts and cicadas belong to the order Hemiptera, they differ in several ways such as their loud buzzing sound (produced by cicadas only), antennae length (longer in cicadas) and feeding habits (locusts form swarms while cicadas are solitary). In addition to this diet, some species of cicada feed on nectar or small insects like aphids and leafhoppers. They mainly feed on plant sap which they extract from tree roots or stems using their proboscis. Unlike locusts, cicadas are generally solitary insects and do not form large swarms like locusts do.Ĭicadas are found all over the world in both tropical and temperate climates. Cicadas also have two long antennae that can be seen extending out of their head. This sound, which can reach up to 100 decibels, is much louder than the noise produced by locusts. The term ‘cicada' is derived from the Greek word ‘kikaros' meaning “buzzing insect”.Ĭicadas produce a very loud buzzing sound by vibrating two membranes located on their abdomen called tymbals. The term ‘locust' is derived from the Latin word ‘locusta', meaning grasshopper. They are noted for their distinct buzzing sound and for the large swarms they form when feeding on crops and other vegetation. Locusts, also knon as cicadas, are a type of insect belonging to the order Hemiptera. The Connection Between Locusts and Cicadas Cicadas feed primarily on sap from trees and shrubs, which typically does not result in the same kind of destruction as a locust swarm. On the other hand, cicadas are not known for causing the same level of destruction as locusts. A swarm of locusts can consume enough vegetation in an area to cause significant damage and crop loss. Locusts are a type of grasshopper that travels in swarms and feed on a variety of plant life. When it comes to destruction of crops and other plant life, locusts are far worse than cicadas. Smaller trees may be vulnerable though, so it is recommended that netting is used for protection against both types of pests if needed.Ĭomparing the Severity of Cicadas and Locusts It is also important to note that in some areas people call cicadas ‘locusts' due to the similarities in appearance between these two insects, but this is incorrect since cicadas cannot eat crops like locusts can and only drink from trees instead. Locusts will often fly away when disturbed while cicadas will remain still if left alone or move slowly away from the disturbance if approached directly. In terms of behavior, cicadas tend to be more passive while locusts tend to be aggressive when disturbed or confronted by humans or animals. Their heads are not as large as those of locusts, and they do not possess powerful mandibles for biting into plants. Cicadas are generally smaller than locusts and their bodies measure up to 1 inch in length. They have an enlarged head with powerful mandibles used for biting through plant material. Locusts tend to be larger, with bodies that measure up to 2 inches long. The physical differences between these two insects are also important to consider when distinguishing between them.
