- Brood X will appear in 14 states. When the soil about eight inches below the surface reaches 64 degrees this spring, cicadas from Brood X will start to claw their way towards the light.
- Brood X is a muse. Back in 1970, three cycles ago, Brood X’s buzz-saw-like calls inspired Bob Dylan to write the song “Day of the Locusts.” Dylan heard the cicadas while receiving an honorary degree from Princeton University and the insects inspired these lyrics
- Cicadas are not locusts. Dylan and Nash shared the misapprehension that the periodical cicada is a type of locust. It is not. Locusts are a type of short-horned grasshopper and belong to the order Orthoptera along with all other grasshoppers and crickets, while cicadas are Hemipterans which are considered “true bugs” and include aphids and planthoppers.
- Cicadas have one of the longest insect lifespans. The 13- or 17-year lifespan of periodical cicadas is one of the longest of any insect, but only a tiny fraction of that time is spent above ground.
In Australia, cicadas are preyed on by the Australian cicada killer wasp (Exeirus lateritius), which stings and stuns cicadas high in the trees, making them drop to the ground, where the cicada hunter mounts and carries them, pushing with its hind legs, sometimes over a distance of 100 m, until they can be shoved down into its burrow, where the numb cicadas are placed onto one of many shelves ...
Magicicada cicadas come out once every 17 or 13 years. Brood X is every 17 years. There are 12 Broods of 17 year cicadas, and 3 Broods of 13 year cicadas. Mathematically speaking, each year there is an approximately 78% chance a Brood is emerging somewhere in the US. If we’re taking about other types of cicadas, they’ll be around late ...
- The next major emergences are Brood XIII (17-year) and Brood XIX (13-year) in 2024. The last time these broods co-emerged was 1803.
- Cicadas “eat” plant sap, specifically xylem. So, technically they don’t eat anything, they drink it. Bacteria in their gut digests it into nutrient...

The superfamily Cicadoldea is split into two subfamilies: Tettigarctidae (aka hairy cicadas), which are mostly extinct save two extant species that occur in southern Australia and Tasmania, and Cicadidae, which can be found on every continent except Antarctica. They thrive in warm environments — especially the tropics — which makes Latin America, A...
That cicadas are often called locusts is deceiving, as they hail from the taxonomic order Hemiptera (true bugs) and locusts belong to the order Orthoptera with grasshoppers. A few behavioral and physical attributes could be the culprit of the misnomer. Firstly, cicadas share a suborder with other "hoppers" of the leaf and frog variety, even though ...
An annual cicada can live between two and five years, and a periodical cicada can live for up to 17 years in the larva stage. That's not quite as long as queen termites are thought to live(50 to 100 years), but it's far more impressive than the average life span of a housefly (15 to 30 days). Cicadas, like most insects, live the majority of their l...
A leading hypothesis for why there are both annual and periodical cicadas, and why the life spans of periodical cicadas vary, is that some broods — located east of the Great Plains in the U.S. only — developed extremely long juvenile stages during the glaciated Pleistocene Epoch.That northern broods tend to remain underground for longer than southe...
Cicadas hatch above ground, about six to 10 weeks after the eggs are laid in cracks and holes in trees. They promptly drop to the ground and burrow up to a foot into the soil, where they remain for up to 17 years. While they're below ground they molt, rather than pupate, through five instars (growth cycles). The most mortality occurs during those e...
It's unclear how many cicadas are included in a single brood, but experts estimate that there are billions. Their portly bodies blanket backyard tree trunks. Their collective songs impede outdoor conversation. Cicadas are known swarmers, but their synchronized emergence is actually a deliberate survival strategy called predator satiation.When an an...
The exact moment when cicadas emerge en masse is very calculated. It happens only when the ground eight inches below the surface reaches 64 degrees Fahrenheit — and not one degree higher of lower.When that temperature is finally reached, the nymphs know it's time to begin their upward journey via a chimney of mud. This usually happens soon after su...
While underground, cicada larvae aren't hibernating; rather, they spend up to 17 years just feeding on trees. They have special straw-like mouths used to suck liquid from plant roots. What they're really after is xylem, a botanical vascular tissuethat helps conduct water and dissolved minerals from the roots. Because xylem tissue is mostly water, c...
In the few short weeks she spends aboveground, the female cicada lays 400 to 600 eggs. She uses her egg-laying organ, the ovipositor, to make rows of pockets in twigs. She'll then lay about 25 eggs in each pocket, and a single twig can hold up to 20 pockets, sometimes creating what looks like long, parallel slits. Tree species popular for cicada eg...
While experts hypothesize that periodical cicadas only emerge every 13 or 17 years to evade repeat predators, because they're slow to mature, and due to the historical necessity of extended juvenile periods, the insects' time-tracking methods have long remained a mystery. Findings from one study indicated that they may use more than just their biol...
Sep 28, 2021 · What do cicadas look like? There are around 3,400 cicada species, of which seven are periodical cicadas (three 17-year cicada species and four 13-year cicada species), according to Scientific ...
Jun 12, 2017 · 1. Cicadas are essentially tiny violins with wings. The body of a cicada is similar to that of a violin or a guitar, in that much of it consists of empty, air-filled spaces that act like a resonating chamber and amplify the sound they generate. "The loud noise we hear is the male's mating call — females are silent," Hall says.

The shrill thorntree cicada (Brevisana brevis), found in Africa, is thought to be the loudest insect in the world. Exceeding 106 decibels, the males’ songs are nearly as loud as a chainsaw (110 decibels). Male cicadas produce loud noises by vibrating membranes (tymbals) near the base of the abdomen. Males of each species typically have three ...
