Dryobius

The species was initially described by Thomas Say, who named it Callidium 6-fasciatum. He placed it in the genus Callidium. In 1850, John Lawrence LeConte transferred the species to be the sole member of his newly-circumscribed genus Dryobius, making the name D. 6-fasciatus. LeConte emended the specific name from 6-fasciatus to sexfasciatus in 1859. In 1957, Earle Gorton Linsley coined the nomen novum Dryobius sexnotatus for this species as there was already a senior homonym with the same specific name used by a beetle described by Guillaume-Antoine Olivier prior to Say's description. The etymology of the generic name comes from the Greek words tree and to live. ==Distribution==

Most specimens of D. sexnotatus come from the Ohio River Valley, but it has been documented in at least fourteen states in the eastern United States. ==Biology==

Its larvae eat maple, beech, basswood, and elm trees. Its flight period ranges from early March through early September, but is most common from mid-June through mud-July. The pheromones produced by males include 1-(1H–pyrrol-2-yl)-1,2-propanedione and (R)-3-hydroxyhexan-2-one. ==References==
