Are Silver Princess Cicadas Harmful To Trees And Plants

This article explores whether the Silver Princess cicadas pose harm to trees and other vegetation. It explains their biology and life cycle, clarifies how their feeding affects landscape plants, and offers practical guidance for gardeners and homeowners.

Overview of Silver Princess Cicadas

Silver Princess cicadas are sizeable insects that emerge in summer months. They are noted for their pale metallic wings and for a loud chorus produced by male adults.

These insects live on many trees and shrubs, and they can appear in urban and rural settings. They rely on a life cycle that spans several years in the soil and a brief period of above ground activity for reproduction.

Life Cycle and Behavior

Life begins when female cicadas insert eggs into tiny slits in tree bark. The eggs hatch into nymphs that drop to the soil and spend years feeding on root fluids.

After the subterranean phase the nymphs crawl out, molt into winged adults, and form seasonal populations.

Adult Silver Princess cicadas emerge during warm periods, sing to attract mates, and die within a few weeks. During this time they are commonly seen on tree trunks and in open spaces.

Feeding Habits and Plant Impact

Adults pierce plant tissues and feed on sap with their specialized mouthparts. Nymphs feed on fluids from plant roots while they develop underground.

Feeding by adults leaves small punctures on leaves and bark, but it rarely damages mature trees. Many trees recover quickly from these marks, especially when conditions are favorable.

Effects on Trees and Shrubs

For established trees the overall harm from a single emergence is usually minimal. The punctures from feeding are typically minor and late season growth is not significantly affected.

Young or stressed trees may suffer more noticeable injuries from oviposition as females insert eggs into twigs. This can cause twig dieback or minor cracking in some cases.

Seasonal Timing and Vulnerable Hosts

For the Silver Princess cicadas the timing of emergence is tied to local climate and seasonal warmth. This pattern varies by region and year and is influenced by rainfall and soil temperature.

Seedlings, saplings, fruit trees with new growth, and other stressed plants are more likely to show damage during the emergence window. The overall impact depends on tree health, weather, and the density of the cicada population.

Management and Prevention

Home gardeners can protect landscapes by focusing on tree health and avoiding unnecessary chemical interventions. Maintaining vigor in trees reduces the risk of lasting damage during cicada emergence.

Practical steps include physical barriers for young trees, timely irrigation, and careful planning related to pruning and lawn care.

Practical steps for homeowners during cicada emergence

• Use tree guards or light netting to deter female oviposition on young branches.

• Water deeply during dry spells to keep trees resilient.

• Avoid broad spectrum insecticides unless directed by local extension services.

• Do not prune during the emergence period and minimize pruning of stressed trees.

• Inspect trees after emergence and remove any dead or damaged limbs promptly.

• If edible crops are at risk, cover them with lightweight mesh or row covers during peak emergence.

These actions reduce risk of serious branch damage while preserving ecological benefits. Homeowners should plan ahead and coordinate with local extension services for current guidelines.

Ecological Role and Benefits

Cicadas are an important food source for birds, small mammals, and predatory insects during their above ground phase. This feeding supports local food webs and can influence predator populations in woodland and garden ecosystems.

In addition to providing prey the seasonal emergences can help aerate soils as nymphs move and die and can enrich the soil as bodies decay. These processes contribute to nutrient cycling and soil dynamics in nearby landscapes.

Common Myths and Misconceptions

One common myth is that cicadas will wipe out mature trees in a single season. In reality established trees are generally capable of withstanding cicada activity.

Another belief is that all cicadas must be eliminated with pesticides. In fact broad spectrum chemicals can harm beneficial insects, pollinators, and natural enemies without significantly reducing cicada populations.

Conclusion

Overall the Silver Princess cicadas are not usually harmful to healthy trees and most landscape plants. They cause little lasting damage and can be part of a balanced ecosystem.

Gardeners who support tree vigor and use careful observation can minimize isolated problems during emergence and still enjoy the ecological contributions of these insects.
