Can You Keep a Cicada as a Pet
Keeping a cicada as a pet is generally not practical or recommended, because most species spend the majority of their lives underground and have very short adult lifespans. Annual cicadas may live several years as nymphs before emerging for only a few weeks, while periodical cicadas emerge in synchronized broods but live only 4–6 weeks as adults. In captivity, adult cicadas struggle to survive beyond a few days without the specific host plants their nymphs depend on, they do not thrive in standard insect enclosures, and they provide limited opportunity for long-term interaction. This overview explains their lifecycle, legal and welfare considerations, housing challenges, and responsible alternatives for observing cicadas.
Lifecycle and Timing
Cicadas are best understood as soil-dwelling nymphs for most of their lives, with a brief adult stage focused on reproduction. Annual cicada nymphs develop in the soil for 2–5 years, feeding on root fluids, before climbing vegetation to molt into adults. Adults emerge primarily to mate and lay eggs; they do not feed solid food and rely on tree fluids early on, but their mouthparts are not adapted for hand-feeding. Periodical cicadas spend 13 or 17 years underground as nymphs, then emerge in massive synchronized broods, mate, and die within 4–6 weeks. Because pet keeping implies ongoing interaction, the naturally short adult window and subterranean juvenile phases make cicadas unsuitable as companion-style pets.
Adult Longevity in the Wild
Adult cicadas typically live 2–6 weeks depending on species and conditions. During this brief period, their energy is directed toward flight, calling, mating, and egg-laying. They are not built for sustained handling or routine care, and they seldom survive more than a week once removed from their host-tree resources. Captive attempts to feed adults often fail because they require xylem-rich fluid from trees or shrubs, not standard artificial diets used for many pet insects.
Nymph Development Period
Below ground, cicada nymphs molt through several instars over years, feeding on root sap. Because they are soil-burrowers, they require deep, stable substrates with appropriate moisture and host-root access. Reproducing these conditions at home is difficult, and removing nymphs from their native soil can harm local populations and disrupt ecosystems. For these reasons, large-scale or long-term 'keeping' of cicadas is not practiced by insect enthusiasts or researchers.
Legal and Welfare Considerations
In many regions, collecting wild cicadas may be restricted by local wildlife or insect collection regulations, especially for protected species or in conservation areas. Removing nymphs or adults from natural habitats can affect population monitoring, research, and ecosystem functions such as soil aeration and nutrient cycling. Ethically, cicadas are not domesticated animals and do not seek or benefit from human handling; their welfare is best supported by allowing natural life cycles to proceed in the landscape. Responsible observation in the wild or through habitat-friendly practices is strongly preferred.
Housing and Survival Challenges
Cicadas require specific conditions that are hard to replicate in typical pet enclosures. Adults need vertical space, secure perches, and access to suitable host plants for oviposition and early nymph survival. Humidity, temperature, and ventilation must be carefully balanced to prevent desiccation or disease. Mesh enclosures designed for flying insects can allow escape, and handling increases stress and decreases survival time. These factors, combined with their brief adult lifespan, mean that housing a cicada long-term offers little practical feasibility for a pet.
Temperature, Humidity, and Light
Stable warmth and moderate humidity are important for cicada activity and molting success. Outdoors, they experience daily and seasonal cycles that influence behavior and development. Indoors, artificial heat and lighting can disrupt natural rhythms and reduce longevity. Providing appropriate host material for egg-laying is especially complex; many twig-laying species require fresh twigs from their preferred trees, which is difficult to maintain consistently in captivity.
Flight and Stress Management
Cicadas are strong fliers and can become stressed in confined or turbulent air conditions. Stress can lead to rapid declines, torn wings, or inability to feed. Because they are not social in the way that ants or bees are, keeping multiple individuals together can increase aggression or competition for space. Netted outdoor observation cages can allow temporary viewing but are not designed for permanent captivity.
Ethics and Responsible Observation
Observing cicadas in their natural habitat supports conservation awareness and allows you to witness behaviors such as calling, molting, and egg-laying without harm. If you wish to study or photograph them, use quiet approaches, minimal handling, and release individuals promptly. Cultivating native trees and shrubs that support cicada nymphs can create long-term habitat benefits. Avoid collecting nymphs or adults for confinement, as this can deplete local populations and is often discouraged by ecological guidelines.
Realistic Alternatives
If your interest is in long-term insect companionship or observation, consider species that are more suitable for captivity, such as certain beetles, mantises, or stick insects that are bred in captivity and have manageable care requirements. For cicada-specific engagement, focus on seasonal observation in gardens or parks, participation in citizen science projects mapping emergence, or creating cicada-friendly landscapes with appropriate host plants. These approaches provide educational value and enjoyment without the welfare and logistical challenges of keeping cicadas as pets.
