Larval: most spp. feed within dead/dying/decaying wood, but some can use living tissue. Girdlers (adult Onciderini, larval Methiini, Hesperophanini, Elaphidiini) sever living branches/twigs, with the larvae developing within the nutrient-rich distal portion. The larvae of a few species move freely through the soil, feeding externally upon roots or tunneling up under the root crown. Adult feeding habits variable; some take sap, leaves, blossoms, fruit, bark, and fungi, often unelated to larval hosts; others take little or no food(21); feeding biology summarized here(22)

Life Cycle
In temperate regions, typically 1‒3 yrs, but cycles of 2‒3 months to decades have been documented. Most of the lifetime is spent in the larval stage; the adults usually emerge, disperse, reproduce, and die within a few days to months. Cellulose digestion aided primarily by enzymes rather than symbiotic microorganisms. Cerambycidae are often primary borers that start the biorecycling.(21)
