Colorado, with its stunning mountain landscapes and diverse ecosystems, is home to a wide array of insects. But are cicadas among them? The answer is both yes and no. While Colorado does have cicadas, they are not the periodical cicadas famous for their synchronized emergences in the eastern United States. Let’s delve into the world of these fascinating insects and discover the types of cicadas that call Colorado home.
Understanding Cicada Life Cycles
Cicadas are classified into two main groups: annual cicadas and periodical cicadas. Annual cicadas, as their name suggests, emerge every year, typically in the late summer months. Their life cycles are much shorter than their periodical counterparts, usually lasting two to five years.
Periodical cicadas, on the other hand, have incredibly long lifespans, spending 13 or 17 years underground before emerging in massive numbers. These emergences are synchronized, meaning that all the cicadas in a particular brood emerge at the same time. This strategy helps to overwhelm predators and ensure the survival of the next generation.
Cicadas You Might Encounter in Colorado
While Colorado does not experience the dramatic emergences of periodical cicadas, the state is home to several species of annual cicadas. These cicadas are often less conspicuous than their periodical relatives, emerging in smaller numbers and with less fanfare. However, their distinctive buzzing calls are a familiar sound in Colorado summers.
One common species found in Colorado is the dog-day cicada, named for its emergence during the hottest days of summer. These cicadas are typically green or brown and have black markings on their wings. They are found throughout the state, often in wooded areas or near streams.
Why No Periodical Cicadas in Colorado?
The absence of periodical cicadas in Colorado is likely due to the state’s climate and geography. Periodical cicadas thrive in areas with warm, humid summers and cold winters. Colorado’s high altitude and dry climate may not provide the ideal conditions for these insects to complete their long life cycles.
The Allure of Cicadas
Despite their sometimes deafening calls, cicadas play a vital role in the ecosystem. Their emergence provides a feast for predators, enriching the food chain. Additionally, their underground burrows help to aerate the soil, benefiting plant life.
Witnessing the Wonder of Cicadas
While you may not encounter the spectacle of a periodical cicada emergence in Colorado, the state’s annual cicadas offer a unique opportunity to observe these fascinating insects up close. Keep an ear out for their buzzing calls during the summer months, and you might be lucky enough to spot one perched on a tree trunk or flying through the air.
