Do Deer Eat Cicadas? (ANSWERED)

As a passionate nature lover and avid deer enthusiast, I often find myself curiously wondering about the dietary habits of these magnificent creatures. One question that has piqued my interest as of late is: do deer eat cicadas? Join me on an exploration of this topic as we delve into the upcoming cicada emergence and the potential feeding frenzy it may bring for our antlered friends.

Deer are known to have a varied diet that changes with the season. While they primarily feed on leaves, fruits, and grasses, they also consume insects, especially during the summer months. Cicadas are believed to be one of the insects that deer may eat. However, there is limited research on the topic, and more studies are needed to confirm their consumption of cicadas. Nonetheless, it is plausible that given the abundance of cicadas, deer may include them as part of their diet during this period.

Do Deer Eat Cicadas?

Deer are not picky eaters when it comes to their diet. They consume various types of plant-based food, fruits, crops, and insects, especially in the summer. Despite their herbivore reputation, deer have been known to consume insects such as beetles, crickets, and grasshoppers.

During the emergence period, cicadas can be found in large quantities and are accessible to predators, including birds, reptiles, mammals, and other insects. This sudden availability of food could cause wildlife populations to increase in short-term or have an impact on breeding patterns. Let’s take a closer look at the impact of the emergence of cicadas on wildlife and their diet.

Therefore, it is possible that they could eat cicadas as well. However, there is limited research on the topic, and more studies are needed to confirm whether deer feed on cicadas or not. Nonetheless, with the billions of cicadas emerging soon, it is plausible that deer might include cicadas as part of their diet during this period.Cicadas are not only a possible food source for deer but also feed for several wildlife species.

Timing of the Cicada Emergence

The emergence of Cicadas largely relies on the soil’s temperature, which must hit around 64 degrees Fahrenheit. Cicada aficionado, Dan Mozgai, explains that these insects tend to make their appearance when the soil is at an ideal temperature. Thus, the timing of their emergence can vary based on weather conditions, but it usually falls between the months of May and June, differing depending on the region and localities.

Regions and Specific Areas of the Emergence

Brood X is set to emerge on a grand scale, spanning from the southernmost tip of the Carolinas to the lush Hudson Valley in New York. However, the emergence’s extent can vary within each state, and its exact time can differ from place to place. Renowned research scientist John Cooley from the esteemed University of Connecticut opines that the Brood X emergence will transpire in ample numbers during May and June.

Approximate Timeline of the Emergence

The emergence of cicadas is expected to take place from mid-to-late May to early July. The emergence could vary depending on the climate conditions, so it is advisable to monitor cicada emergence sightings to get detailed forecasts.

Impact on Wildlife

The cicada emergence can have a considerable impact on wildlife, affecting species that prey or get preyed on by insects. The increase in the population of cicadas can impact many wildlife species positively and negatively. The short-term effect could result in increased population of wildlife species, nest, or brood survival.

Effects on Birds, Reptiles, Mammals, and Other Insects

Cicadas can impact wildlife species positively and negatively. In the short term, it could cause a boost in population or nest and brood survival. Birds, reptiles, mammals, and other insects are among the species that can be positively or negatively affected by the emergence of cicadas. Different species have different interactions with cicadas.

Role of Cicadas in the Food Chain and Food Web

Cicadas are an essential part of the food chain and food web of several wildlife species. The abundance of cicadas is essential in providing alternative food and prey to many species. Cicadas are also essential in predator satiation.

Possible Changes in Breeding Patterns of Affected Species

The temporary surge in cicada numbers can alter the breeding habits of various wildlife species. For instance, certain songbird varieties tend to produce more nests, greater quantities of eggs, and start reproducing earlier thanks to the overwhelming food supply. Research also suggests that short-tailed shrew populations can spike up by four times during a cicada emergence year.

Human Observation of Cicadas

People can easily observe cicadas emerging from the soil or singing in trees. Cicadas are known for their loud, wavy, and constant calling, making them easy to locate.

Cicada enthusiasts can observe, document and even photograph cicadas.Overall, cicadas‘ emergence impact on deer‘s diet is still not clear-cut, but it is plausible that they might feed on cicadas given their rich availability. The emergence of cicadas has a short-term impact on wildlife and breeding patterns, and the sudden boost of food supplies can increase populations of several wildlife species, including deer.

Tips on How to Observe Safely and Responsibly

When observing cicadas and wildlife that interact with them, it is important to do so safely and responsibly. Here are some tips:

  • Wear long sleeves and pants to protect your skin from cicada exoskeletons, which may cause irritation or allergic reactions for some people.
  • Use insect repellent with DEET to deter biting insects, such as ticks and mosquitoes, that may also be present during the cicada emergence.
  • Stay on the trails and avoid trampling on vegetation or cicada emergence holes, as they may be important to local ecosystems.
  • Be respectful of other observers and their equipment, especially if you are in a crowded observation site.
  • Do not disturb or harm cicadas or other animals for close-up photos or observations. Wildlife needs space to carry out their natural behaviors.

By following these tips, you can minimize any negative impacts on the environment and maximize your own safety while observing cicadas and other wildlife.

Equipment Needed for Observation

Observing wildlife during the cicada emergence can be a rewarding and fun experience. Here are some useful equipment and tools to bring along on your observation trips:

  • Binoculars or a spotting scope can help you see details of wildlife that may be far away or in trees.
  • A camera or smartphone for taking photos or videos can allow you to share your experiences with others.
  • A field guide or online resource for identifying cicadas and other insects can be helpful in learning more about them.
  • A notebook or smartphone app for recording your observations can help you keep track of what you see and where you see it.
  • A backpack or shoulder bag to carry your equipment and supplies can keep you organized and comfortable.

Remember to pack lightly and only bring what you need for a safe and enjoyable experience observing cicadas and wildlife.


What is the purpose of cicadas being underground for 17 years?

During the majority of their lives, cicadas remain hidden from sight underground. They stay in this state of hibernation for up to 17 years, emerging only for a brief period of time before returning back underground. While below the surface, they feed on the sap of tree roots and make tunnels through the dirt. This avoidance of predators and prolonged underground habitation allows the cicadas to survive, until they are finally ready to emerge in masses for their once-in-a-lifetime reproductive cycle.


So, do deer eat cicadas? The answer is, we’re not entirely sure. While there is evidence to suggest that deer may consume cicadas during their emergence, more research is needed to confirm this. However, with the mass emergence of cicadas this spring, we may soon have an answer to this question.

Regardless of whether or not deer choose to indulge in some cicada snacking, the upcoming emergence is sure to be a feeding frenzy for many animals. From birds to squirrels to even our pets, the cicada emergence is a unique opportunity for animals to feast on this once-in-a-lifetime bounty. So, grab a lawn chair, sit back, and see for yourself who comes to the cicada buffet.
