1. What Are Lantern Flies?
Lantern flies, or spotted lanternflies ( Lycorma delicatula ), are invasive planthoppers native to Asia that have become a significant concern in the United States, particularly in states like Pennsylvania and New Jersey. They are not true flies but belong to the order Hemiptera, known for their piercing-sucking mouthparts used to feed on plant sap. According to research from Penn State Extension in July 2025, spotted lanternflies pose a threat to various agricultural and horticultural industries.
1.1. Identification
Identifying spotted lanternflies is essential for effective management and control. Adults are approximately 1 inch long and 0.5 inches wide, with distinctive markings. The forewings are gray with black spots, while the hindwings have patches of red, white, and black. Nymphs (immature stages) undergo several instars, starting as black with white spots and developing red patches as they mature.
1.2. Life Cycle
Understanding the life cycle of lantern flies is crucial for targeting management strategies. The life cycle consists of four stages:
- Egg: Eggs are laid in masses covered with a mud-like substance on trees, rocks, and other surfaces.
- Nymph: Nymphs hatch in the spring and go through four instars, each with distinct color patterns.
- Adult: Adults emerge in late summer and early fall, focusing on feeding and reproduction.
- Reproduction: Females lay eggs in the fall, which overwinter and hatch the following spring.
1.3. Host Plants
Lantern flies feed on a wide range of host plants, but they have a particular affinity for the tree of heaven ( Ailanthus altissima ), an invasive tree species. Other host plants include fruit trees, grapevines, hardwood trees, and ornamental plants. This broad host range contributes to their ability to thrive and spread in new environments.
