Do Lantern Flies Have a Natural Predator

Do lantern flies have a natural predator? Yes, they certainly do, and some of these predators are unexpectedly effective.

It was a hot summer afternoon, and the grapevines were drooping under the weight of ripening fruit. 

Suddenly, a flurry of red and gray wings interrupted the stillness—a swarm of spotted lantern flies had arrived. 

Their appetite for sap and their numbers were daunting, but just as despair set in, a flash of green—a praying mantis—darted from a nearby bush, snatching a lanternfly out of the air. 

It was a reminder that nature has its own way of keeping balance. Let’s dive into it!

1. Spotted Lanternfly (Lycorma delicatula)

Do lantern flies have a natural predator: Spotted Lanternfly (Lycorma delicatula)

  • Origin: Native to China, India, and Vietnam, the spotted lanternfly has spread to other parts of Asia and more recently to North America, where it has become an invasive species. Its rapid spread outside of its native range has posed significant ecological and agricultural challenges.
  • Description: The spotted lanternfly is easily recognized by its gray forewings adorned with black spots and striking red hindwings. It is about 1 inch (2.5 cm) in length and has a distinctive polka-dotted pattern. The bright red hindwings are typically only visible when the insect is in flight, serving as a warning to potential predators.
  • Habitat: The spotted lanternfly prefers the Tree of Heaven (Ailanthus altissima), which is also an invasive plant species, but it is highly adaptable and feeds on a wide variety of plants. These include economically important crops such as grapes, maples, black walnuts, and apple trees. It is often found in woodlands, orchards, and vineyards, which are also areas where its presence can cause substantial damage.
  • Natural Predators:
    • Birds: Chickens and some wild birds such as gray catbirds and eastern bluebirds.
    • Praying Mantises: These ambush predators are capable of capturing and eating spotted lanternflies.
    • Spiders: Orb-weaving spiders catch them in their webs.
    • Wheel Bugs (a type of assassin bug): Prey on spotted lanternflies by immobilizing them with their sharp beak.
    • Entomopathogenic Fungi: Beauveria bassiana and Batkoa major are known to infect and kill them, providing effective biological control.

2. Peanut-Headed Lanternfly (Fulgora laternaria)

  • Origin: Found throughout the Amazon Rainforest in South America, this species is particularly common in countries like Brazil, Colombia, and Peru. It thrives in the humid and biodiverse environment of the Amazon, which provides ample food and shelter.
  • Description: This species is known for its large, elongated head that looks similar to a peanut or even resembles the head of a reptile. The wings are decorated with striking eye-like patterns, which are believed to deter predators by mimicking the eyes of larger animals, potentially making the insect seem more dangerous.
  • Habitat: The peanut-headed lanternfly lives in tropical rainforests and is often found resting on tree trunks, where its camouflaging colors blend well with the bark. It feeds on the sap of various tropical trees, using its piercing-sucking mouthparts to access nutrients.
  • Natural Predators:
    • Birds: Large birds may target these insects despite their intimidating appearance.
    • Spiders: Web-building spiders may capture these lanternflies when they are resting or moving along vegetation.

3. Lanternflies of the Genus Pyrops (Pyrops spp.)

  • Species: Includes species such as Pyrops candelaria.
    • Origin: Native to Southeast Asia, including countries like Thailand, Malaysia, and Indonesia. These regions provide the warm and humid conditions that these lanternflies need to thrive.
    • Description: Lanternflies of the genus Pyrops are known for their bright, colorful patterns that vary from species to species, typically involving shades of green, yellow, and red. They have a long, snout-like head projection that extends forward, giving them a unique and recognizable appearance.
    • Habitat: These lanternflies are typically found in tropical and subtropical forests, usually on tree trunks where they feed on tree sap. The forests of Southeast Asia provide an ideal mix of temperature and humidity for these insects.
    • Natural Predators:
      • Birds: Some small birds are known to eat these lanternflies, though the bright colors serve as a warning.
      • Lizards: Arboreal lizards occasionally hunt and feed on lanternflies found on tree trunks.

4. Zanna terminalis (Zanna spp.)

Do lantern flies have a natural predator: Zanna terminalis (Zanna spp.)

  • Origin: Native to parts of Africa and Southeast Asia, particularly in regions with dense forests. These areas provide the appropriate environment for their survival, including high humidity and abundant vegetation.
  • Description: Zanna terminalis has a more subdued coloration, typically brownish with intricate markings that allow it to blend in with tree bark. Its head is not as pronounced as some other lanternflies, but its body length is quite noticeable, which helps in distinguishing it from other species.
  • Habitat: Prefers tropical forests and is mainly found on tree trunks, where it blends well to avoid predators. The cryptic coloration helps it remain unnoticed by both predators and humans. It uses its piercing mouthparts to feed on the sap of a variety of host plants.
  • Natural Predators:
    • Praying Mantises: These generalist predators can catch Zanna species when they are still or moving slowly.
    • Spiders: Web-building spiders can catch these lanternflies, especially if they attempt to move through low vegetation.

5. Kalidasa lanata

Do lantern flies have a natural predator: Kalidasa lanata

  • Origin: Found in South Asia, particularly in India and Sri Lanka. The warm climate and presence of various host trees in these regions create ideal conditions for this species to thrive.
  • Description: Kalidasa lanata has a stout body with vibrant red and yellow tones. The contrasting wing patterns serve as a warning signal to potential predators, indicating that the insect might be distasteful or toxic. Its unique coloration makes it visually striking compared to other lanternflies.
  • Habitat: Usually found in subtropical forests and open woodlands, feeding on sap extracted from a variety of host trees. These forests provide both the climate and food sources necessary for its survival, allowing it to move freely between host trees.
  • Natural Predators:
    • Birds: Some birds are known to consume these lanternflies, though the bright colors and sudden wing flashes can sometimes dissuade them.
    • Frogs: Amphibians like frogs may prey on Kalidasa species when they descend to lower vegetation or ground levels.

6. Fulgora Lampetis

Do lantern flies have a natural predator: Fulgora Lampetis

  • Origin: Found in the Amazon Basin, including parts of Brazil and Colombia. The rich biodiversity and variety of plant life in the Amazon make it an ideal habitat for Fulgora lampetis.
  • Description: This species is brightly colored, featuring a mix of red, yellow, and black. The enlarged head is reminiscent of a lantern, although it does not emit light. The bright colors likely serve as a deterrent to predators, signaling that the insect may be dangerous or unpalatable.
  • Habitat: Found in tropical rainforest canopies, typically feeding on the sap of tall trees. The canopy layer provides both protection from ground-based predators and access to food sources rich in nutrients.
  • Natural Predators:
    • Tree-Dwelling Frogs: Feed on lanternflies in the canopy.
    • Birds: Small rainforest birds target these lanternflies as a food source.

7. Spotted Lanternfly Natural Control in Native Range

In their native regions (Asia), spotted lanternflies face pressure from natural predators such as Dryinus browni, a parasitic wasp that lays its eggs inside the lanternfly. 

This natural parasitism helps control their populations but is not found in areas where they have become invasive. 

This addresses the question: Do lantern flies have a natural predator? Yes, they do, especially in their native regions where specific predators have evolved alongside them.

Summary

Lanternflies are visually fascinating but can be problematic pests, especially in non-native environments.

They have various natural predators that help regulate their populations. Birds, insects like praying mantises and wheel bugs, and certain fungi (such as Beauveria bassiana) are effective in keeping them in check.

In tropical and subtropical environments, these predators, alongside biological control methods, help manage lanternfly populations and limit their impact on the environment.
