Injury first appears early in the spring on the emerging shoots. The 12-spotted beetles escape by flight. They may scoot over and hide on the other side of the stalk, may do the classic Chrysomelid drop to the ground, or may resort to secretions from defensive glands. The spotted asparagus beetle, Crioceris duodecimpunctata, looks very similar in appearance, but is not related. Crioceris, or asparagus beetle, is a genus of the family Chrysomelidae of beetles. The adult beetles are red, yellow, and black in colour and about 7 mm (almost 0.3 inch) long. They're a type of long-horned beetle from the Cerambycidae family. The common asparagus beetle is the first to wake up, and it also feeds on the lacy leaves, which can defoliate and weaken the plant, a perennial (no leaves = no photosynthesis = no food storage) and can make it susceptible to fungal infections. Sheaves of asparagus shiver on beds of ice in grocery stores, and foragers are anxious for those first stalks of “volunteer” asparagus to peek up along the roadsides. Identification.
