The Meimuna Cicada (Meimuna opalifera) is a member of the order Hemiptera and the family Cicadidae. It is a familiar summer insect found throughout East Asia, including South Korea, Japan, and eastern China. Although slightly smaller than the Giant Cicada, it is well known for its clear, melodious song that fills forests and parks during the summer months. Like other cicadas, it has a unique life cycle, spending several years underground as a nymph before emerging as an adult for only a few weeks. The species also plays an important role in maintaining healthy forest ecosystems.

In this article, we’ll explore the Meimuna Cicada’s characteristics, habitat, behavior, diet, reproduction, and ecological importance.

What Is the Meimuna Cicada?

The Meimuna Cicada belongs to the order Hemiptera and the family Cicadidae.

It is distributed mainly throughout South Korea, Japan, and eastern China, where it inhabits deciduous forests, parks, gardens, and tree-lined urban streets.

Adult Meimuna Cicadas typically measure:

• Body Length: Approximately 30–40 mm (1.2–1.6 inches)
• Wingspan: Approximately 70–90 mm (2.8–3.5 inches)
• Weight: Approximately 1–2 g (0.04–0.07 ounces)

Adults generally live for 2–4 weeks, while the underground nymph stage lasts approximately 3–5 years before the insects emerge and undergo their final molt.

Characteristics of the Meimuna Cicada

1. Clear and Melodious Song

The Meimuna Cicada is famous for its bright, rhythmic song, one of the characteristic sounds of East Asian summers.

Male cicadas rapidly vibrate specialized sound-producing organs called tymbals located on the abdomen to attract females and establish breeding territories.

2. Transparent Wings and Well-Camouflaged Body

The Meimuna Cicada has two pairs of transparent wings and a brown to olive-brown body.

Its coloration blends well with tree bark, providing effective camouflage against predators.

3. Long Underground Nymph Stage

The Meimuna Cicada spends the majority of its life underground.

Its nymphs feed on sap from tree roots for several years before emerging during summer. After climbing onto a tree trunk or another vertical surface, they molt one final time and transform into winged adults.

Behavior

The Meimuna Cicada is a diurnal insect that is most active during the daytime.

Its typical behaviors include:

• Living primarily in trees
• Only males producing mating calls
• Being highly active during daylight hours
• Laying eggs in tree branches after mating
• Emerging mainly during the summer season
• Spending several years underground as nymphs

Females use their ovipositors to make small slits in tree branches where they deposit their eggs. After hatching, the young nymphs fall to the ground and burrow into the soil to begin their long period of underground development.

Diet and Habitat

The Meimuna Cicada is a herbivorous insect that feeds exclusively on plant sap.

Its primary food sources include:

• Tree sap
• Oak tree sap
• Maple tree sap
• Zelkova tree sap
• Willow tree sap

Nymphs feed on sap from tree roots, while adults obtain nutrients by piercing tree trunks and branches to drink sap.

Preferred habitats include:

• Deciduous forests
• Mixed forests
• Parks
• Gardens
• Tree-lined urban streets
• Mountain forests

The species prefers environments with abundant mature trees and dense vegetation.

Ecological Importance

The Meimuna Cicada plays an important role in forest ecosystems.

Underground nymphs improve soil aeration and drainage as they tunnel through the ground. Both nymphs and adults serve as valuable food sources for birds, spiders, praying mantises, amphibians, and many other animals, helping maintain healthy food webs.

In addition, the shed exoskeletons left behind after molting become part of the natural decomposition process and provide temporary shelter for small organisms.

Relationship with Humans

The Meimuna Cicada is harmless to humans.

It does not bite, sting, or transmit diseases and is widely appreciated as one of the signature sounds of summer.

Because it is commonly observed in parks, forests, and urban green spaces, it is frequently used in environmental education and nature observation. It is also regarded as an indicator of healthy green ecosystems.

The Meimuna Cicada is one of East Asia’s most familiar summer insects, admired for its clear song and remarkable life cycle. After spending several years developing underground, it emerges as an adult for only a brief period to reproduce, making its life history one of the most fascinating among insects.

With continued conservation of forests, parks, and urban green spaces, the Meimuna Cicada will continue to announce the arrival of summer with its beautiful song while contributing to healthy forest ecosystems for generations to come.
