Cicadas. Cicadas form the Cicadoidea superfamily of insects.
Katydids and crickets are excellent examples of nighttime noise-making insects. These insects, which belong to the same Order (Orthoptera) make noises in similar ways: by rubbing their wings together. These insects usually make their high pitched chirping noise at night to attract mates or to warn off predators.
An African cicada, Brevisana brevis, is the Worlds loudest insect. Its loudest song is almost 107 decibels when measured at a distance of 20 inches (50 cm) away.
Cicadas are famously known for their buzzing, which often rises and falls in both pitch and volume. In summers when cicadas populations are very high, the effect can be quite startling, with insects seemingly calling and responding to each other across the treetops. But did you know that only males produce sound?
The truth is, in most cases, they do not. Most of the time when you hear an insect at night it is a cricket or katydid. However, there are a few cases when cicadas will sing at night: In the presence of artificial light sources, like streetlights & floodlights, or a full moon.
Some of the larger species of Australian cicadas can produce sounds measuring over 120 decibels and at close range can be uncomfortably loud. Many cicada species call in chorus, timing their individual drones in sync with others around them, resulting in a deafening 'mexican wave' of sound moving through the forest!
Australia is the cicada capital of the globe with more than 700 species, many of which are yet to be described. Most of a cicada's lifespan is spent underground, which Emery says is likely another reason the invertebrates are more abundant in some years than others.
Cicadas are not harmful to humans, pets, household gardens, or crops. Periodical cicada adults are about 1-1.5 inches long and have a wingspan twice that length. They have black bodies, large red-brown eyes, and membranous wings with orange veins. Cicadas are often noticed due to adult males' loud courting sounds.
Myth: Cicadas will harm you or your pets
Cicadas have been around since the age of the dinosaurs. And they can't hurt you, said Elizabeth Barnes, exotic forest pest educator at Purdue University. People tend to worry that cicadas will bite, but they don't have the mouthparts to do that, she said.
The Common Garden Katydid is frequently seen in Sydney and most cities in Australia throughout the year.
Sevin Insect Killer Concentrate, used with a pump-style sprayer, is ideal for treating lawn areas and small trees and shrubs at risk for cicada damage. Spray all plant surfaces thoroughly to kill cicadas by contact and protect against cicadas for up to three months.
The Krakatoa volcanic eruption: Not only did it cause serious damage to the island, the eruption of Krakatoa in 1883 created the loudest sound ever reported at 180 dB. It was so loud it was heard 3,000 miles (5,000 km) away.
Whales: 230db
But the loudest is the sperm whale. It makes a series of clicking noises that can reach as high as 230 db making it the loudest animal in the world. The click lasts for only 15 to 30 milliseconds and can stay audible to a sperm whale as much as 10 miles away.
Katydids, crickets, and cicadas are the three types of bugs primarily responsible for those classic summery insect noises you hear at night. Whether you find them calming, irritating, or either one depending on the scenario, here's the story behind the loud chirping noises bugs make.
The Greater Sooty Owl is native to the south-eastern forests of Australia and is nocturnal, spending its days in tree hollows, caves and under rock overhangs. Its typical call is known as a 'falling bomb whistle', a short, descending screech or shriek that can be heard over long distances.

Stop squishing bugs, they feel pain! With the recent advancements of technology, new and compelling evidence shows that insects feel pain. This also includes chronic pain, which lasts long after an injury or trauma.
Cicadas obtain sustenance by drinking tree fluids, which are relatively watery compared to human blood. Drinking human blood would probably kill a cicada. Caution: Don't hold cicadas in a closed fist — you can hurt the cicadas, and they might try to drink from your hand meat.
But the bugs have no real interest in people: After 17 years of munching on roots underground, the brood emerges to hastily mate and lay eggs.
Male cicadas have sound boxes in their abdomens. They make their sound by expanding and contracting a membrane called a tymbal. They use their sound to attract females, which make clicking noises when they are ready to mate. The hotter the day, the louder the male cicadas make their sounds.
Cicadas live an average of 10-20 years total, with very little of their life spent above ground. After spending sometimes more than a decade underground, some cicadas live a brief time above ground that measures in weeks.
No, they just might seem like it when they are flying into you. Cicadas have five eyes, according to Cicada Mania. Cicadas have two obvious compound eyes and three ocelli, which are believed to detect light and darkness.
There are more than 200 Australian species of cicadas, most of which belong to the one large family, the Cicadidae. Cicadas are sometimes known as locusts in Australia, but that term is more correctly applied to certain migratory species of grasshopper.
Not only do they tend to sing at night but also during hot weather, and as a pack. Why? To escape predators. A single, singing cicada is extremely vulnerable.
The peak Cicada season is November and December.
