RECOGNITION
A cosmopolitan family of beetles, characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family the antennae are quite short and such taxa can be difficult to distinguish from related beetle families. Body length in America, north of Mexico is 3-60 mm. However, worldwide taxa may be 3-150 mm.
Body Length
3-60 mm.

BIOLOGY
Food
Larval habits: Most species feed within dead, dying or even decaying wood, but some taxa can use living plant tissue. Girdlers 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. Many adults (especially the brightly colored ones) feed on flowers. Adult feeding requirements are variable, with some species taking nourishment from sap, leaves, blossoms, fruit, bark, and fungi, often not associated with larval hosts; others take little or no nourishment beyond water.
Development
The life spans in temperate regions typically range from 1 to 3 years, 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 appears to be aided primarily by enzymes rather than symbiotic microorganisms. In many cases, Cerambycidae are primary borers, providing a vital "first step" in the biorecycling of wood.
Distribution
Worldwide from sea level up to 4,200 m elevations, subject to host plant availability.
