Black and Orange Bugs (Pictures) – Insect and Bug Identification
Black and orange bugs are a common sight in gardens and landscapes. These creepy crawlies come in various shapes and sizes. Some bugs with black and orange bodies, like ladybugs and beetles, can be beneficial insects. In contrast, other black and orange bugs can be nuisance pests that can bite, destroy plants, or stink when squished. Sometimes, the colorful bugs and insects can invade homes.
Identifying black and orange bugs is essential for understanding their impact on your garden. It’s also vital to know if small critters with orange and black coloration can be dangerous in the house.
This article provides pictures and descriptions of black and orange bugs to help with insect and bug identification. You can learn about the different species of bugs that have black and orange markings, including beetles, weevils, stink bugs, and other insects.
How to Identify Black and Orange Bugs and Insects
Identifying black and orange bugs requires observing their color, size, shape, and markings. For accurate identification, you can also pay attention to characteristics like their wings, antennae, legs, and body structure. Also, comparing the black and orange bugs with pictures can help identify individual insects or arachnid species.
Some people use the term “bug” as an all-encompassing term for any small insect. However, not all annoying insects with black and orange bodies are bugs in the scientific sense. “True bugs” are six-legged insects belonging to the order Hemiptera. These arthropods have piercing mouthparts to bite and suck the juice from plant tissue.
The article refers to all types of six-legged insects as bugs, whether classified in the order Hemiptera or not.
Types of Orange and Black Bugs (With Pictures) — Identification Guide
Let’s look in more detail at various types of bugs, beetles, and insects with black and orange coloration.

The best way to get rid of boxelder bugs is to prevent their access into homes in late summer and fall. Therefore, you should seal around window frames and doors, remove wood piles and debris near your home, and use window and door screens. Additionally, you could remove boxelder trees from your property to stop the nuisance pest from laying eggs where boxelder nymphs live.
