Types of Orange Beetles (With Pictures) – Identification Guide

Types of Orange Beetles (With Pictures) - Identification Guide

Orange beetles are unusual insects due to their various orange shades and black markings. It’s not uncommon to find orange-colored beetles in gardens scurrying over foliage or running across the ground. You may also come across beetles with orange bodies in your home. The most common type of orange beetle is probably tangerine-colored ladybugs. However, orange soldier beetles, scarab beetles, and longhorns are all common garden insects.

Most varieties of orange beetles are harmless creatures. And some varieties of orange-bodied beetles are beneficial because they feed on garden and household pests. However, a few kinds of orange beetles can give a harmless bite if they feel threatened.

There are several types of orange beetles, each with their own unique characteristics. Knowing what type of orange beetle you’re dealing with can help you determine its behavior and identify other similar species.

This identification guide includes pictures of different types of orange beetles along with information on where to find them.

Orange Beetle Identification

Orange beetles are identified by their size, markings on their wing cases (elytra), type of antennae, pronotum (thorax), and body shape. Some orange beetles have spotted backs, whereas others have stripes or irregular markings. Like all beetle species, orange beetles have six legs, a pair of antennae, and wings.

Orange beetles — like all species of beetles — are arthropods belonging to the insect order Coleoptera. Beetles are grouped into genera and species to help identify specific kinds. There are over 400,000 species of beetles, a few of which have distinct orange and black colors.
