On a hot summer day, stepping outside to water a maple tree can lead to an unexpected discovery. Imagine noticing an unusual insect resting on a branch, its gray wings covered with small black spots. At first glance, it may look harmless, but its distinctive appearance could be a clue that you have spotted an invasive pest.

One insect that matches this description is the spotted lanternfly, an invasive species native to parts of Asia. It has grayish forewings decorated with black spots, while its hindwings feature striking red, black, and white markings. When its wings are folded, the insect can blend surprisingly well with tree bark, making it easy to overlook.

Spotted lanternflies feed on plant sap by using their mouthparts to pierce plants and draw out their fluids. They can gather in large numbers on trees and other plants, weakening them over time. As they feed, they also release a sugary substance called honeydew, which can encourage the growth of black sooty mold and attract other insects.

Although maple trees may attract spotted lanternflies, the insects are known to feed on many plant species, including grapevines, fruit trees, and ornamental plants. They are considered a serious agricultural and environmental concern in areas where they have become established. However, not every gray insect with dark spots is a spotted lanternfly, so identification is important before taking action.

If you discover a suspicious insect in your yard, take a clear photograph and compare it with images from your local agricultural extension or plant-health authority. If you confirm or strongly suspect a spotted lanternfly, follow local reporting guidelines, as recommendations vary by region. A simple afternoon spent watering the garden can become an opportunity to discover something fascinating—and potentially help protect the plants growing around your home.
