The Dog Day Cicada, also known as the Tibicen canicularis, is a species of cicada that is commonly found in North America, particularly in the United States and Canada. These insects are known for their distinctive songs, which are often heard during the summer months, and are a sign of the warm weather that typically occurs during this time. The Dog Day Cicada is one of the most common species of cicadas found in North America, and is often encountered in urban and rural areas alike.
Life Cycle and Behavior
The Dog Day Cicada has a unique life cycle, which consists of three main stages: egg, nymph, and adult. The female cicada lays her eggs in the ground, usually in the fall, and the eggs hatch into nymphs after a period of several weeks. The nymphs then feed on the roots of plants and trees, growing and developing over a period of several years. Once the nymphs have reached maturity, they emerge from the ground and undergo a process called ecdysis, in which they shed their skin and emerge as adult cicadas.
Adult Characteristics
Adult Dog Day Cicadas are relatively large, with a body length of approximately 2-3 inches (5-7.5 cm). They have a distinctive green or brown coloration, with a black stripe that runs along their back. The males are known for their loud, buzzing songs, which are used to attract females and establish territory. The females, on the other hand, do not produce sound, but are instead attracted to the songs of the males. The adult cicadas are also characterized by their large, compound eyes, which are made up of thousands of individual lenses, giving them excellent vision.

Ecological Importance
The Dog Day Cicada plays an important role in the ecosystem, serving as a food source for a variety of animals, including birds, bats, and spiders. The cicadas are also an important part of the nutrient cycle, helping to break down plant material and recycle nutrients. Additionally, the cicadas are an indicator species, helping to monitor the health of the environment and detect any changes or disturbances.
Predators and Prey
The Dog Day Cicada has a number of natural predators, including birds, such as the Common Grackle and the American Robin, as well as bats, such as the Little Brown Bat. The cicadas are also preyed upon by spiders, such as the Golden Orb Weaver, and other insects, such as the Praying Mantis. In turn, the cicadas feed on the sap of plants and trees, helping to regulate the growth and development of these organisms.
