Asian Long-Horned Beetle
Asian long-horned beetles (ALB) are shiny black with white spots. The antennae are long and have alternating bands of black and white. The antennae are usually 1 to 2 times greater than the length of the body. The upper sections of the legs are whitish to blue.
The larvae are yellowish-white, wormlike, cylindrical and fleshy, with a varied texture on the underside.
The pupae are off-white to light brown and appear like an immature version of the adult with legs and antennae compressed against the body.
The ALB should not be confused with the cottonwood borer, a native long-horned beetle. The adult cottonwood borer has a more even mix of black and white patterns on its body and has solid black antennae.
