Explanation of Names
(κεραμβυξ), a type of horned beetle; may be derived from karabos
(καραβοσ) 'beetle' + keras
~1000 spp. in 300+ genera in our area, ~10,300 spp. in almost 1900 genera in the Western Hemisphere and >30,000 spp. in >5000 genera worldwide(3)(1)(4)
Overview of our fauna
, except that we keep the Disteniinae as a subfamily. * –taxa not yet in the guide, with links to Bezark’s Catalog(5)

Tribe Disteniini Elytrimitatrix
Tribe Parandrini Parandra
; in our area, 3-60 mm(6)
Keys and visual guides:
(good for most se. US spp.)
worldwide from sea level up to 4,200 m elevations, subject to host plant availability(1)
Larval: Most species feed within dead, dying or even decaying wood, but some taxa can 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.(1)
Many adults (esp. the brightly colored ones) feed on flowers.(6)
Adult feeding habits variable; some species take nourishment from sap, leaves, blossoms, fruit, bark, and fungi, often not associated with larval hosts; others take little or no food(1)
Feeding biology summarized here(19)
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.(1)
