Dryobius sexnotatus is a species of beetle in the family Cerambycidae. It is the only species in the monospecific genus Dryobius.

Taxonomic history

[edit]

The species was initially described by Thomas Say, who named it Callidium 6-fasciatum. He placed it in the genus Callidium.[1] 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.[2] LeConte emended the specific name from 6-fasciatus to sexfasciatus in 1859.[3]

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.[5]

The etymology of the generic name comes from the Greek words δρῦς tree and βιόω to live.[6]

Distribution

[edit]

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.[7]

Biology

[edit]

Its larvae eat maple, beech, basswood, and elm trees.[7]

Its flight period ranges from early March through early September, but is most common from mid-June through mud-July.[7]

The pheromones produced by males include 1-(1H–pyrrol-2-yl)-1,2-propanedione and (R)-3-hydroxyhexan-2-one.[8]
