Dryobius sexnotatus is a species of beetle in the family Cerambycidae. It is the only species in the monospecific genus Dryobius.
The species was initially described by Thomas Say, who named it Callidium 6-fasciatum. He placed it in the genus Callidium . [2] 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. [3] LeConte emended the specific name from 6-fasciatus to sexfasciatus in 1859. [4]
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 δρῦςtree and βιόωto live. [6]
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]
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]
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.
Pleocoma is the only extant genus of rain beetles and is endemic to the Pacific states of North America. Fossil remains of Pleocoma have been found in the Yixian Formation in China, suggesting beetles in this genus have existed in something like their present form since at least the Cretaceous period. There are 27 described species in Pleocoma.
The Boridae are a small family of tenebrionoid beetles with no vernacular common name, though recent authors have coined the name conifer bark beetles. The family contains three genera. Boros is native to North America and northern Eurasia, Lecontia is endemic to North America, while Synercticus is found in Australia and New Guinea. The larvae of Boros are found under bark and are especially associated with standing dead trees (snags), typically pines, found in old-growth forests. Lecontia larvae are found inhabiting damp parts of the root system of dead standing trees. Little is known of the life habits of Synercticus.
The Disteniidae are a small family of beetles in the superfamily Chrysomeloidea, traditionally treated as a group within the Cerambycidae.
Lepturinae, the lepturine beetles, is a subfamily of the longhorn beetle family (Cerambycidae), containing about 150 genera worldwide. This lineage is most diverse in the Northern Hemisphere. Until recently the subfamily Necydalinae was included within the lepturines, but this has been recently recognized as a separate subfamily. Nine tribes are usually recognized today, with a tenth, Caraphiini, created in 2016. A few genera are of uncertain placement within the subfamily.
Sternidius is a genus of flat-faced longhorns in the family of beetles known as Cerambycidae. There are at least 20 described species in Sternidius.
Brachysomida is a genus of beetles in the family Cerambycidae, containing the following species:
Stenocorus is a genus of beetles in the family Cerambycidae, containing the following species:

Aneflomorpha is a genus of beetles in the family Cerambycidae, containing the following species:
Meganoplium is a monotypic beetle genus in the family Cerambycidae described by Linsley in 1940. Its single species, Meganoplium imbelle, was first described by John Lawrence LeConte in 1881 as Elaphidion imbelle.
Trachyderini is a tribe of long-horned beetles in the family Cerambycidae. There are at least 140 genera and 650 described species in Trachyderini.
Tylosis is a genus of beetles in the family Cerambycidae, containing the following species:
Dorcasina matthewsii is a species of flower longhorn in the beetle family Cerambycidae. It is found in North America and was described by John Lawrence LeConte in 1869.
Typocerus deceptus is a species of flower longhorn in the family Cerambycidae. It is found in North America.
Ampedus is a genus of click beetles in the family Elateridae. There are currently 461 recognized species of Ampedus beetles. It has a cosmopolitan distribution, but is found mostly in the Holarctic region, primarily in North America, Europe, and Asia. The oldest known fossil from this genus was found in Eocene Baltic amber, estimated to be from 38.0–33.9 million years ago.
