Yes. Both the common and spotted asparagus beetle can cause the damage you describe. They begin feeding as the plants emerge in spring and produce a second generation that feeds on the greenery and causes defoliation. Control these pests by handpicking and dropping the beetles and their worm-like larvae into a container of soapy water. Use insecticides as a last option. These chemicals also kill the parasitic wasp that helps control these pests. Handpicking along with weed control and fall cleanup is usually sufficient to minimize damage.
