Most Cerambycidae larvae feed within dead, dying or even decaying wood, but some taxa are able to use living plant tissue. Girdlers (adults of the Onciderini, larvae of genera in the tribes Methiini, Hesperophanini and Elaphidiini) sever living branches or 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.Most adult cerambycids, particularly the brightly colored ones (such as the bright red beetle featured here), feed on flowers and pollen, and as such can be important pollinators of some flowering plants. Other species consume sap, leaves, blossoms, fruit, bark or fungi.
