I don’t know how it is where you live, but people around here don’t know the difference between a cicada and a locust. It seems trivial, I know, but it’s really like comparing nuns to Nazis. So let me spell it out for you.
Locusts are basically identical to grasshoppers when alone, but when a bunch of them get together they form a swarm and devastate crops as they migrate over huge distances. They’re destructive pests, and nobody has ever considered them friends (check the Bible if you doubt me).
Cicadas, however, have a completely different story. There are many different varieties of cicadas. They all live underground for most of their lives, but each species stays buried for a different number of years (5, 7, 11, 17, etc.). I’ll use the 17-year cicada as an example of how they live. Try to stick with me…it’s not quite as boring as it may sound.
In mid-late June, adult female cicadas plant their eggs deep in the 2-3 year old shoots of a host tree. They continue to move down the stem planting more eggs in rows for quite a while. These eggs hatch in August and the newly emerged nymphs drop to the soil and burrow in to the ground near the tree where they feed on roots for the next 17 years.
Around April of the emergence year the nearly mature nymphs will tunnel to the surface once the soil has thawed and warmed. Then they will go back down about a foot for another month. The purpose of tunneling to the surface in April is to construct an emergence hole while the soil is still moist, because they know they can’t count on the ground being soft when the time is right. In early June the nymphs emerge in large numbers and crawl up onto any available surface. There they will shed their skin, dry out their new wings, and consider themselves adults.
Male cicadas “sing” in the evenings for most of the summer. They don’t make their music by rubbing their legs against their wings like locusts or grasshoppers do. Instead, they force air through a specialized organ in their abdomen.
Cicadas carry out a highly specialized “job”. Their life cycle actually benefits healthy trees by providing a natural pruning of their branches and roots every 17 years, and aerates the soil in the process.
So lets think about this for a second. Remember that if any individual part of this life cycle wasn’t inherent in the very first cicada ever, it would have died immediately and never been able to reproduce. This is just further evidence that macroevolution is a fantasy. There is virtually no evidence to support it…merely a dogmatic adherence to Darwin’s theory -- which, by the way, he himself admitted could not stand on its own and would have to be supported by fossil evidence that had not yet been discovered. Well, 150 years later we’ve found millions of new fossils that simply complicate his lack of evidence. There are many more types of prehistoric creatures than he had surmised, and none of them represent transitional forms or show the broadening of species variation over time. In fact, we basically see all major phyla appearing suddenly in the fossil record with no explanation as to where they came from.
Ummm…so anyway…all I was really trying to say is that a locust is nothing like a cicada. I guess that post got a little out of hand.
