Types of Green Beetles (With Pictures) – Identification Guide

Green beetles are fascinating insects with smooth bodies, six legs, and two antennae. Some stunning green beetle species have iridescent colors and glittery metallic green bodies. Green June beetles (Cotinis nitida) are green-bodied beetles with a lustrous green body and bronze markings. They are the most common green-bodied beetles. Despite the fact that most beetles are harmless, beetle larvae have the potential to harm lawngrass, attractive plants, and even soft furnishings inside homes.

The phylum Arthropoda and the order Coleoptera are home to beetle species. Beetles have six legs, a three-part body with a head, thorax, and abdomen, and two antennae, as do all insects. Green beetles with elytra, which are their hardened wing cases, are also common.

The tiniest beetle is about 0.15” (4 mm) long, while the biggest is approximately 2″ (50 mm). Beetles with iridescent green colors, such as the mint leaf beetle or Japanese beetle, are easy to see in a landscape because of their stunning iridescence. Other green beetles that do not have a lustrous green abdomen, such as the pale green weevil, may be more difficult to distinguish in a garden because they blend in with foliage.

This article aims to help differentiate between several species of green beetles by providing an identification guide. You’ll get precise descriptions to aid identify the green bug you discovered on plants or in your home, in addition to pictures of green beetles.

Green Beetle Identification

Green beetles are distinguished by their habitat, antennae type (clubbed or serrated, pincers or mandibles near their mouth), and green color. The two hard green wing covers, which mean the wings won’t be visible from up close, may be seen. The beetle species’ body form makes it easy to distinguish in some situations.

Green, brown, and black beetles are not insects in the scientific sense, despite how many people refer to them as such. The order Hemiptera contains the true bugs. Shield bugs and stinky bugs, for example, seem to be pale green beetles. True bugs, on the other hand, do not belong to the beetle order Coleoptera.

Types of Green Beetles (With Pictures) — Identification

Let’s take a closer look at some of the green beetles with lustrous metallic green bodies, including ones. Others, on the other hand, have dull dark green wing cases.

Green June Beetle (Cotinis nitida)

Green June beetles have antennae that split at the end and a bronze gold body with emerald green highlights. The elytra of the green beetles, which are iridescent green and brown on the underside, and green on top, are also gold-colored. The green insects have short, dark brown antennae that split near the tip, which you may also see.

Green June beetles are a 1″ (25 mm) long and 0.5″ (13 mm) broad beetle that can be found in large numbers. These active mid-summer flying green beetles have a name that says it all. Fruit like apples, pears, peaches, plums, and nectarines are eaten by metallic green beetles.

They are sometimes known as fig-eaters because they prefer figs. The figeater beetle (Cotinis mutabilis) is, nonetheless, a distinct but related species. Green June beetle larvae are cream-colored and grow to be up to 2 inches (5 cm) long. When they feed on roots, the fat, C-shaped grubs may harm lawns, turfgrass, and decorative plants.

Green beetle identification

The velvety green body with dull bronze or gold edges and shading are distinguishing characteristics of the green June beetle. In mid to late summer, green beetles may be seen flying or crawling on the ground or plants.

Green Fruit Beetle (Cotinis mutabilis)

The green fruit beetle, sometimes known as the western green beetle or figeater beetle, has a huge metallic green body with bronze edges and clubbed antennae. The horn-like protrusion on the head, huge legs, and enormous size are additional identifying traits of the green fruit beetle.

The length of the green fruit beetle ranges from 0.75 to 1.3 inches (20 to 34 mm). Adults will frequently eat sweet, soft-skinned fruits. Grape, peach, pear, tomato, and figeater beetles are among the fruit types that feed on them. Because of their sweetness, they are also attracted to fermenting or ripening fruit. The larvae of green fruit beetles and June beetles are different in that they don’t harm lawns. As a result, instead of being an invasive pest, green fruit beetles are merely regarded a minor nuisance in residential gardens.

Green beetle identification

The dull, metallic green body, brilliant iridescent underside, and black clubbed antennae distinguish the green fruit beetle from other scarab beetles.

Japanese Beetles (Popillia japonica)

Each side of the Japanese beetle has white tufts with iridescent green and copper hues. The unique five white tufts along the base of a Japanese beetle’s abdomen are an instantly noticeable characteristic. The invasive Japanese beetle is distinguished from similar-looking June beetles by its white markings.

The Japanese beetle is 0.3 to 0.4 inches (8 to 11 mm) long and wide, with a maximum width of 0.27 inch (7 mm). Lawns and tree and plant foliage are devastated by iridescent green bug populations. Plant foliage skeletonized by adult Japanese beetles can make trees and shrubs look unsightly in a matter of minutes.

Moreover, Japanese beetle larvae feed on lawn grass roots and survive in the soil. The larvae emerge and grow from Japanese beetle eggs placed in the earth. Eventually, when they’ve grown up, Japanese beetles climb out of the earth to cause havoc. Unfortunately, eradicating Japanese beetles and preventing them from destroying your lawn is made difficult by their beetle life cycle.

Green beetle identification

The bright green and bronze abdomen, green thorax, and white tufts on the sides of the Japanese beetle distinguish it from other beetles.

Green Tiger Beetle (Cicindela sexguttata)

The metallic-green beetle with blue-green legs and serrated antennae may be recognized by its long legs and six white markings on the rear body. Because of the conspicuous cream-colored spots on its elytra, the common green ground beetle is also known as the six-spotted green tiger beetle.

Its long spindly legs and huge mandibles are other identifying characteristics. The 0.55″ (14 mm) large, swift-moving reflective green tiger beetle is an adult. It feeds on little arthropods such as caterpillars, spiders, and ants and is typically found in deciduous woods. The green tiger beetle’s speed is another behavioral habit. It can fly if necessary and is one of the quickest ground beetles.
