Life Cycle of Jewel Beetle
Egg The insect begins life as an egg, which is typically oval or round. The egg's color and texture can vary but is often designed to blend with the surrounding environment for protection.
Larva As larvae, they are significantly different from adults, often worm-like with a soft, elongated body. This stage is dedicated to eating and growth, and as they grow, they molt several times.
Pupal During pupation, the jewel Beetle undergoes a remarkable transformation within a protective casing. The creature is generally immobile, reorganizing its internal structures and developing adult features.
Adult Emerging from the pupa, the adult jewel Beetle’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Jewel Beetle Through Different Life Stages
The larvae of jewel Beetle typically reside within the wood of their host trees, burrowing under the bark and consuming the inner layers as they grow. When searching for larvae, you would inspect the trunks and branches of hardwood trees, looking for signs of tunneling or the larvae themselves deep within the wood. Adult jewel Beetle, on the other hand, can often be found on the outer surfaces of trees or in foliage, where they feed and mate. To find adults, one might search on leaves, flowers, or bark where they might be basking or feeding during warm, sunny days.

When is the Best Time to Observe Jewel Beetle
The best time to find adult jewel Beetle is during warm, sunny days when they are most active, especially during the late spring and summer months.
Rectangle
What is the Best Weather to Observe Jewel Beetle
Adult jewel Beetle are typically more active in dry weather conditions as high humidity can impact their flying capability.

How and Where Can You Find Jewel Beetle at Different Life Stages
Larva Larvae of jewel Beetle are found within wood, under the bark of trees, or in the soil. To locate them, examine decaying logs, dead trees, or woody debris. One may have to carefully split or peel bark or dig in soil near the roots of trees to find them.
Pupal Pupae of jewel Beetle generally continue to reside in the same habitat as the larval stage. Gentle excavation near the larval habitat can reveal pupae. They are often found within cocoons or pupal chambers in wood, so careful investigation is essential to avoid harming them.
Adult Jewel Beetle adults can be found on the surface of wood, on foliage, or flying in sunny areas. Observing the host trees during peak activity times, such as midday when the sun is strongest, can increase chances of sighting. Adults are attracted to certain types of trees or plants which can be identified through further research on jewel Beetle.

Hurt Plant

Jewel Beetle larvae bore into stems and roots, disrupting the plant's vascular system, often leading to weakened structure and vitality. Adult damage is less significant but can contribute to decline. The severity varies with the infestation level.
