Alright, get ready for a rerun this year. The exhibit of insects kicks off as early as April. This year, broods XIII and XIX of cicadas are predicted to emerge from the ground to mate and lay eggs. It is unusual for them to emerge in the same year. It was the last recorded instance in 1803. The cycle of Brood XIII lasts 17 years. The Midwestern states of Illinois, Iowa, Wisconsin, and Kentucky are home to them. There is a 13-year cycle for Brood XIX. They will appear in a region that stretches southeast from Indiana and Illinois to the southern states of Georgia and Alabama.
More than a trillion cicadas are predicted by scientists to emerge in a few limited regions where the two broods are adjacent to one another. When the earth reaches a temperature of approximately 18 degrees Celsius, the insects will start to emerge from the ground. Thus, as early as April, they will be observed in warmer southern regions. Before the cicadas appear in Wisconsin, Indiana, and other Midwestern states, summer will arrive, maybe in June. Cicadas are big, loud insects that range in length from 2.5 to 5 centimeters. They have wings, just like most insects. They also have large eyes that bulge. Worldwide, there are thousands of different species of cicadas.
When it’s time for mating, male cicadas make a thrumming sound with their wings on their bodies. Women find the “singing” appealing. After mating, the insects deposit their fertile eggs on trees. The resulting young break out of their shells and fall to the ground. They burrow into the earth and spend years there, consuming the liquid that is produced by tree roots. North America is home to seven of the nine recognized species of periodical cicadas. One type is located in India, and the other is exclusive to the island nation of Fiji.
