Life Cycle of Ladder-marked longhorn beetle
Egg The egg stage begins with the female ladder-marked longhorn beetle laying her eggs, often on host plants. The eggs are small, oval, and may vary in color. This stage is relatively short and focused on protection and development of the embryo inside.
Larva After hatching, the larval ladder-marked longhorn beetle emerges as a grub-like creature, consuming plant material voraciously. Its primary function is to grow, which it does by molting several times. Each molt increases the larva's size; color and patterns may also change.
Pupal Having reached the prerequisite size, the larva enters the pupal stage, often encased in a cocoon or burrowed into plant material. Inside this protective chamber, the ladder-marked longhorn beetle undergoes remarkable transformation, reshaping its body and organs.
Adult Emerging from the pupa, the adult ladder-marked longhorn 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 and possibly feeding.

When is the Best Time to Observe Ladder-marked longhorn beetle
The best time to find adult ladder-marked longhorn beetle is usually from late spring to summer when they are most active. For larvae, the suitable time would be during their feeding period, which may vary but often occurs in the late summer to fall.
Rectangle
What is the Best Weather to Observe Ladder-marked longhorn beetle
Adult ladder-marked longhorn beetle are more active in warm, sunny weather, while larvae can be found in various weather conditions as they are usually burrowed in host trees or plant matter.

How and Where Can You Find Ladder-marked longhorn beetle at Different Life Stages
Larva Ladder-marked longhorn beetle larvae are typically found within the wood of their host trees. To find them, look for trees with signs of damage or boreholes and carefully remove sections of bark to inspect for larvae.
Pupal Ladder-marked longhorn beetle pupae are normally located inside the wood or under the bark of their host trees. Finding them requires peeling back the bark or cutting into the wood where larval activity has been noted.
Adult Adult ladder-marked longhorn beetle can be found on or near their host trees. Searching for them involves checking the trunks and branches of trees, especially during warm evenings when they might be most active or feeding on sap flows or fermenting fruit.

Forestry Pest

Ladder-marked longhorn beetle larvae bore into stems, disrupting the transport of nutrients. Mildly infested trees may show slower growth, while a severe attack can kill young trees. This pest poses indirect threats to industries relying on these trees.

Rectangle
Hurt Plant

The ladder-marked longhorn beetle can inflict mild to severe damage to a variety of host plants during its larval and adult stages. Larvae primarily bore into stems, disrupting the plant's vascular system, while adults chew on leaves, which can lead to defoliation and a decrease in the plant's photosynthetic capabilities.
