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.
Types of Orange Beetles — Identification Guide With Pictures
Let’s look in detail at the most common kinds of orange beetles and how to identify them.
Common Red Soldier Beetle (Rhagonycha fulva)
The common red soldier beetle is a small reddish-orange beetle with a distinctive black marking on its wing tips. Identifying features of the slender oblong beetle are its flat body, black and orange antennae, shiny orange head and thorax, and orange and black legs.
The common red soldier beetle measures 0.3” to 0.4” (8 – 10 mm) long. Due to its dark orange, sometimes red color, the beetle is called the bloodsucker beetle. However, this harmless reddish-orange beetle doesn’t bite humans and doesn’t suck blood. In addition, unlike many species of flying beetles with hard wing cases, this one has a soft body.
This orange beetle is considered a beneficial insect because it feeds on aphids and insect larvae. The orange-colored beetle is active in summer, where its primary habitat is grasslands.
Orange beetle identification
The common red soldier beetle is identified by its elongated shape, orange head, thorax, legs, and reddish-orange elytra.
Red Pumpkin Beetle (Aulacophora foveicollis)
The red pumpkin beetle is recognized by its oval orange-red or orange-yellow elytra, shiny head, and two black pinhead eyes. In addition, this small dark orange beetle has slightly rounded wing cases, slender filiform antennae, and a black abdomen. The beetles and their larvae can destroy crops.
The red pumpkin beetle measures 0.2” to 0.3” (5 – 8 mm) long. It’s a type of leaf beetle because of its appetite for vegetation. The orange beetle feeds on plants in the gourd family, especially pumpkins — hence the name pumpkin beetle. But they also feed on plants like cucumbers, squash, watermelon, and muskmelon.
Orange beetle identification
The red pumpkin beetle’s identifying characteristics are its orangey-red oval wing cases, shiny red thorax and head, and two pronounced big black eyes on the side of its head.
Goldenrod soldier beetle (Chauliognathus pennsylvanicus)
The goldenrod soldier beetle is a slender orange insect commonly found in North America. The orange beetle has a distinctive black patch on each wing cover, a black mark on its orange thorax, and a black head. In addition, the black and orange beetle has long black legs.
Goldenrod soldier beetles measure 0.62” (15 mm) long. The flying beetles have orange soft wing covers, and the black oval patches make them easy to recognize during summer when they are most active. During the fall, the beetles and their larvae live in the soil.
Also called the Pennsylvania leatherwing, you will find goldenrod soldier beetles in grassy fields, meadows, and woodlands. They are common on goldenrod flowers and other late-flowering plants. These omnivores also feed on caterpillar eggs and aphids, making them beneficial beetles.
