Jewel beetles, belonging to the family Buprestidae, are among the most visually stunning insects in the world. Known for their brilliant metallic colors and iridescent bodies, these beetles are found in a wide range of habitats, from tropical forests to dry woodlands. Their shimmering appearance often makes them easy to recognize, but identifying individual species can still be challenging due to their diversity.
This guide covers 25 different types of jewel beetles, highlighting their key identification features, habitats, behaviors, and life cycles. Some species are harmless and play a role in decomposition, while others are known pests that damage trees and crops. Whether you are a nature enthusiast, student, or researcher, this list will help you better understand and identify these fascinating beetles.
1. Agrilus planipennis
Agrilus planipennis, commonly known as the emerald ash borer, is a highly destructive jewel beetle famous for its metallic green color. Native to Asia, it has become an invasive species in many parts of the world, causing severe damage to ash trees.
Identification
- Small size, about 8–14 mm long
- Slender, elongated body shape
- Bright metallic emerald green coloration
- Elytra narrow and tapering toward the end
- Head relatively flat with large black eyes
- Underside may show a purplish or coppery tone
Habitat and Distribution
This beetle is native to northeastern Asia but has spread widely to North America and parts of Europe. It primarily inhabits areas where ash trees (Fraxinus species) are present, including forests, urban landscapes, and plantations. Infestations are often found in both natural and human-managed environments.
Behavior and Diet
Adults feed on ash leaves, causing minor damage. However, the larvae are the most harmful stage, boring into the inner bark and disrupting the tree’s ability to transport water and nutrients. This feeding behavior eventually leads to tree death. Adults are active during warmer months.
Life Cycle
Agrilus planipennis undergoes complete metamorphosis. Eggs are laid on the bark of ash trees. After hatching, larvae tunnel beneath the bark, creating distinctive S-shaped galleries. They overwinter inside the tree, pupate, and emerge as adults, typically completing one life cycle per year depending on climate.
2. Agrilus biguttatus
Agrilus biguttatus, commonly known as the two-spotted oak borer, is a jewel beetle recognized for its metallic sheen and association with oak trees. It plays a role in forest ecology but can become problematic when populations increase, especially in stressed or weakened trees.
Identification
- Medium size, about 8–13 mm long
- Slender, elongated body typical of jewel beetles
- Dark metallic green to bronze coloration
- Two distinct pale or whitish spots near the rear of the elytra
- Elytra smooth and slightly tapered toward the end
- Antennae short and serrated
Habitat and Distribution
This species is primarily found across Europe and parts of western Asia. It inhabits deciduous forests, particularly those dominated by oak trees (Quercus species). It is more commonly found in warmer regions and areas where trees are under environmental stress, such as drought-affected forests. The beetle prefers mature woodlands but may also appear in parks and managed landscapes.
Behavior and Diet
Adult beetles feed on oak leaves, usually causing minimal visible damage. The larvae, however, live beneath the bark of oak trees, where they feed on the inner tissues. This feeding creates winding galleries that disrupt the tree’s vascular system. While healthy trees can often tolerate low infestations, weakened trees may suffer significant damage, making this species an indicator of declining forest health.
Life Cycle
Agrilus biguttatus undergoes complete metamorphosis. Females lay eggs in bark crevices of oak trees. After hatching, larvae bore into the cambium layer and feed while creating tunnels. The larval stage can last one to two years depending on environmental conditions. Pupation occurs within the tree, and adults emerge through small exit holes, typically during late spring or summer.
3. Agrilus anxius
Agrilus anxius, known as the bronze birch borer, is a destructive jewel beetle that primarily targets birch trees. It is native to North America and is considered a serious pest, especially for ornamental and stressed birch species.
Identification

- Slender, elongated body
- Bronze to dark metallic brown coloration
- Elytra narrow and tapering toward the tip
- Head slightly flattened with noticeable eyes
- Exit holes are D-shaped, a key identification sign
Habitat and Distribution
This beetle is widespread across North America, particularly in regions where birch trees (Betula species) are common. It is frequently found in forests, urban landscapes, and residential areas where birch trees are planted. The species tends to infest trees that are stressed due to drought, poor soil, or environmental conditions.
Behavior and Diet
Adult beetles feed on birch leaves, causing only minor damage. The larvae are the primary threat, as they tunnel beneath the bark and disrupt the flow of nutrients and water. Infested trees often show signs such as dieback, thinning canopy, and eventual death. The beetle is especially harmful to non-native birch species.
Life Cycle
Agrilus anxius follows complete metamorphosis. Eggs are laid on the bark of birch trees. Larvae hatch and bore into the tree, feeding in the cambium layer and forming serpentine galleries. The larval stage may last one or two years. Pupation occurs within the tree, and adults emerge through characteristic D-shaped exit holes during warmer months.
4. Chrysochroa fulgidissima
Chrysochroa fulgidissima, commonly known as the jewel beetle or “tamamushi,” is one of the most visually striking species due to its brilliant iridescent colors. It has cultural significance in Japan, where its wing covers have been used in traditional art and decoration.

Larvae bore into dead or dying pine wood, creating tunnels as they feed. While they can occasionally infest weakened trees, they primarily target already compromised wood.
Life Cycle
Chalcophora virginiensis undergoes complete metamorphosis. Eggs are laid on bark, and larvae tunnel into wood, where they develop over one to two years. Pupation occurs within the wood, and adults emerge through oval exit holes, usually during late spring or summer.
