These little black and orange bugs are called boxelder bugs. They get their name from their close association with boxelder trees. I’ve come across these bugs many times in my gardening and landscaping work, and they are quite fascinating creatures.
Boxelder bugs are native to the western states but can be found in other regions as well, including eastern Canada and the eastern United States. They can also be found as far west as eastern Nevada. Their distribution is closely tied to the presence of boxelder trees, as these bugs rely on the tree for food and shelter.
The coloration of boxelder bugs is what makes them stand out. They have a distinctive combination of black and orange markings on their bodies, which makes them quite eye-catching. The black coloration serves as a protective mechanism, helping them blend in with the dark bark of the boxelder tree. The bright orange markings, on the other hand, act as a warning signal to potential predators, indicating that the bugs are not safe to eat.
I remember one particular encounter with boxelder bugs while working on a landscaping project near a boxelder tree. As I was pruning some branches, I noticed a cluster of these bugs gathered on the trunk. It was fascinating to see how they moved in unison, almost like a synchronized dance. Their bright orange markings really stood out against the dark bark, and it was a sight to behold.
Boxelder bugs are part of the true bug family, known as Hemiptera. They have a distinct body shape with a triangular or shield-like structure. They have a pair of wings, but only the fully developed adults can fly. The nymphs, or young boxelder bugs, do not have wings and are smaller in size.
These bugs are primarily herbivores, feeding on the seeds, leaves, and sap of boxelder trees. They have specialized mouthparts that allow them to pierce through the plant tissues and extract the nutrients they need. While boxelder bugs primarily feed on boxelder trees, they can also be found on other related trees such as maple and ash.
One interesting behavior of boxelder bugs is their tendency to gather in large numbers, especially during the fall. They seek shelter in protected areas, such as cracks and crevices in buildings, to overwinter. This behavior can sometimes lead to infestations in homes and other structures, as the bugs find their way indoors in search of warmth and protection.
To manage boxelder bug populations, it’s important to take preventive measures. Sealing up cracks and gaps in the exterior of buildings can help prevent these bugs from entering. Additionally, removing boxelder trees or treating them with insecticides can also help reduce the presence of boxelder bugs in the vicinity.
These little black and orange bugs are boxelder bugs, which are commonly found on and around boxelder trees. Their striking coloration and interesting behaviors make them a unique and intriguing insect to observe. Whether you encounter them in your garden or find them seeking shelter in your home, understanding their habits and taking preventive measures can help manage their populations effectively.
