Life Cycle of Spruce Zebra Beetle
Egg The egg of spruce Zebra Beetle is typically oval and minute. It's deposited in a secure environment where it remains until hatching. Color might blend with the substrate to evade predators.
Larva Upon hatching, larvae of spruce Zebra Beetle bore into wood. They undergo several molts, growing considerably in size. Initially, they are legless and pale but darken and develop a hardened exoskeleton over time.
Pupal The pupal stage occurs within the wood. During this phase, spruce Zebra Beetle is immobile, and significant reorganization occurs as tissues differentiate, developing structures characteristic of adult insects.
Adult Emerging from the pupa, the adult spruce Zebra 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 Spruce Zebra Beetle Through Different Life Stages
The larvae of spruce Zebra Beetle are commonly found in the inner wood of oak trees as they prefer to feed on the decaying or weakened wood tissues during their development. Searching for larvae involves peeling back bark or examining trees with signs of damage or disease. Adults are typically spotted on or near the host trees, often on the bark or leaves, during warm months. They are also attracted to lights at night. To find them, one should inspect the trunks and branches of oak trees, especially in the evening or at night when adults are more active and visible.

How and Where Can You Find Spruce Zebra Beetle at Different Life Stages
Larva Larvae of spruce Zebra Beetle are typically found within dead or decaying wood. To find them, inspect logs, stumps, or trees that show signs of damage or disease. Carefully split or peel back the bark on infested wood to reveal the larvae without harming them.
Pupal Pupae of spruce Zebra Beetle are usually hidden inside the wood where larvae developed. Finding them involves carefully cutting into the wood or waiting for adults to emerge.
Adult Adult spruce Zebra Beetle are most often found on or near their host trees. Look for them on the bark, leaves, and flowers, especially during the morning or late afternoon when they are most active. Using light traps at night can also attract adult spruce Zebra Beetle.

Forestry Pest

Larvae of spruce Zebra Beetle bore into coniferous tree stems, disrupting water and nutrient flow. Minor infestations may cause growth deformities, while severe cases result in tree death. This can lead to forest health decline and may affect timber industries and ecosystems reliant on coniferous forests.
