When many solitary phase locusts are present, these locusts undergo physiological changes and produce offspring of gregarious phase. The gregarious locusts have a black and yellow or orange coloration in a pattern and they gather in a large group. These types of locusts are very active and they have high metabolic rates.
After producing a dense population of locusts, the majority of the local population shifts to gregarious migratory phase. Again, the gregarious phase locusts produce an offspring of solitary locusts. The formation of gregarious phase locusts is a physiological response of locusts to violent fluctuations in the environment. The long distance dispersal of locust swarms occurs with the help of the front winds of the storms or high-level jet stream winds.
Figure 2: Locusta migrotoria gregarious phase. The control of the locust plague is almost impossible. Still, by applying insecticides, using insecticidal baits and hopperdozers and destroying egg masses, the plague can be controlled. The gregarious phase locust is shown in figure 2.
Cicadas are a type of insects, whose male insects make buzzing and clicking noises by flexing their tymbals. The tymbals are drum-like organs found in the abdomen of the insect. The smooth muscles connected to the tymbals pull the tymbals in and out rapidly, making a noise.
The noise is intensified by the abdomen of the insect. The majority of cicadas are found in the family Cicadidiae. The cicadas are the actual cousins of crickets. The cicadas have a beak, which can be used to suck fluids in the xylem of plants.
The female cicadas produce rice-shaped eggs. Once the eggs hatch, the cicada that comes out looks like a small white ant. Amy Jorgensen has ghostwritten more than articles and books on raising and training animals. She is also an amateur dog trainer.

Names of Crop-Eating Insects. This is a fabulous piece, Jen. It was very well done, and answers many questions? Now, where did the mention of the year locust come from? This is very interesting, well organized, and filled in some details that I need to know. If I am not mistaken, the fascinating outer covering of the cicada was what we would delight in finding around our property in the late summer.
Would that be correct? Hi Jen this is a very interesting and informative article, some of this information i did not know before, thanks for helping learn more about these little critters.
