What Is a Spotted Lanternfly?

The spotted lanternfly (Lycorma delicatula) is an invasive insect native to Asia, specifically China, India, and Vietnam. It was first identified in the United States in 2014 in Berks County, Pennsylvania [source]. It is an invasive pest that poses a serious threat to various plants in North America.

This insect is not a true fly; rather, it’s a planthopper belonging to the order Hemiptera, which includes true bugs, aphids, and cicadas. The spotted lanternfly is quite distinctive, growing up to an inch long and featuring large, brightly colored wings. Although these insects can fly, they often prefer to jump and glide [source].

Spotted lanternflies can cause significant damage to plants. They feed on a wide range of plant species, including fruit, ornamental, and woody trees, with the tree-of-heaven being one of their preferred hosts [source]. As they feed on the sap of plants, they excrete a sticky substance called honeydew, which promotes the growth of sooty mold, negatively affecting plant health and fruit production.

Keep in mind the spotted lanternfly is an invasive species, and it’s essential to take appropriate measures to control and eradicate it. If you ever encounter these insects, follow the recommendations of experts to report and control them effectively [source].

Lifecycle of the Spotted Lanternfly

The lifecycle of the Spotted Lanternfly starts with egg masses. Female lanternflies lay their eggs on various surfaces, such as tree trunks and outdoor furniture. These egg masses are covered in a muddy-looking substance to protect them during the winter. In the spring, nymphs hatch from these eggs and begin their journey to become adults¹.

Nymphs go through four developmental stages, known as nymphal stages². In the early stages (1st-3rd instars), they have black bodies, legs, and bright white spots. They’re a few millimeters in length and grow to around 1/4 inch as they age¹. These young nymphs are strong jumpers, showcasing this ability when prodded or frightened¹.

As nymphs progress to the 4th instar, their appearance transforms. Their bodies acquire a red coloring in addition to the black and white spots they already have. Once they reach the final nymphal stage, they’re not long away from becoming adults².

Adult Spotted Lanternflies might look like moths when their wings are spread, but they’re actually planthoppers belonging to the order Hemiptera, making them more closely related to cicadas, brown marmorated stink bugs, aphids, and leafhoppers². The entire life cycle of the Spotted Lanternfly takes roughly one year, with adults living long enough to mate and lay eggs before dying².

In summary, the Spotted Lanternfly’s life cycle consists of the following stages:

• Egg masses: Laid by females on various surfaces, protected by a muddy-looking substance.
• Nymphs: Hatch from eggs, go through four nymphal stages, starting with black bodies, legs, and white spots, then progressing to a red, black, and white appearance.
• Adults: Resemble moths when wings are spread, but are actually planthoppers related to cicadas and other Hemiptera insects.

By understanding the life cycle of the Spotted Lanternfly, you can better identify and manage this invasive species.
