Life Cycle of Long-horned beetle
Egg During the egg stage, the long-horned beetle remains encapsulated, typically adhering to a surface within its environmental niche. The egg is minute and initially displays a translucent quality, with changes in coloration as development proceeds.
Larva After hatching, the larva of long-horned beetle exhibits an elongated, soft-bodied form, lacking fully developed wings and reproductive structures. The larva molts several times, significantly increasing in size and occasionally altering in color with each instar.
Pupal Transforming into the pupal stage, long-horned beetle becomes immobile and forms a protective casing around itself. The organism undergoes significant internal reorganization, with its size remaining constant but the body progressively taking on the adult’s characteristics.
Adult Emerging from the pupa, the adult long-horned beetle is characterized by a hardened exoskeleton, functional wings, and reproductive organs. Its size and coloration are now definitive, and the insect's behavior transitions to focus on dispersal, mating, and oviposition.

How and Where Can You Find Long-horned beetle at Different Life Stages
Larva Long-horned beetle larvae bore into dead or dying wood, particularly in cacti. To find them, search for infested plants by looking for entry holes or sawdust-like frass around the base of cacti.
Pupal Long-horned beetle pupae remain inside their larval feeding chambers within the host plant. Locating pupae involves carefully cutting into the wood of infested plants while avoiding damage to the pupae.
Adult Long-horned beetle adults can be found on or near their host plants, particularly at night. They can be located by searching with a flashlight or by setting up light traps that attract the insects.

Hurt Plant

Long-horned beetle can cause a range of damage from mild to severe. Both adults and larvae feed on plant tissues, primarily stems and leaves, without a preference for plant type. As a result, affected plants may show chew marks, defoliation, and weakened structural integrity.
