Monochamus carolinensis
Carolina Pine Sawyer
Monochamus carolinensis is a longhorn beetle in the subfamily Lamiinae, commonly known as the Carolina Pine Sawyer. It is a significant vector of the pinewood nematode Bursaphelenchus xylophilus, the causative agent of pine wilt disease. The species is native to North America, occurring in Canada and the United States, and has been detected in China. Adults are attracted to blacklights and are associated with pine forests.
Monochamus clamator
spotted pine sawyer
Monochamus clamator, the spotted pine sawyer, is a species of longhorn beetle in the family Cerambycidae described by LeConte in 1852. The species exhibits several recognized subspecies across western North America and has been documented in pine woodland habitats. Research indicates host plants serve as a selective pressure driving genetic divergence in this species. Adults have been observed at blacklights and on stressed or dead pine trees.
Monochamus clamator latus
Spotted Pine Sawyer
Monochamus clamator latus is a subspecies of the spotted pine sawyer, a large longhorned beetle in the family Cerambycidae. Adults are active during summer months and are attracted to blacklights. The species breeds in dead, dying, or stressed coniferous trees, particularly pines. Adults have been observed on trunks of stressed Pinus ponderosa, with males exhibiting mate-guarding behavior.
Monochamus clamator nevadensis
Spotted Pine Sawyer
Monochamus clamator nevadensis is a subspecies of the spotted pine sawyer, a longhorned beetle in the family Cerambycidae. It belongs to a genus of large woodboring beetles that infest coniferous trees, particularly pines. The subspecies was described by Dillon & Dillon in 1941 and is distributed in western North America, including Nevada and surrounding regions. Like other Monochamus species, it develops in dead, dying, or stressed coniferous wood and is attracted to blacklights at night.
Monochamus clamator rubigineus
Spotted Pine Sawyer (for species complex)
Monochamus clamator rubigineus is a subspecies of longhorned beetle in the family Cerambycidae, described by Bates in 1880. It belongs to the Spotted Pine Sawyer species complex, which are large woodboring beetles associated with coniferous forests. Adults are active during summer months and are attracted to blacklights. The species breeds in dead, dying, or stressed pine trees.
Monochamus maculosus
spotted pine sawyer
Monochamus maculosus, the spotted pine sawyer, is a longhorned beetle native to North America. It was formerly known as Monochamus mutator. Adults are attracted to monochamol, a sex-aggregation pheromone produced by males. The species breeds in stressed or recently dead conifers, with larvae tunneling in phloem and sapwood. It is a primary vector of the pinewood nematode, the causal agent of pine wilt disease.
Monochamus notatus
northeastern pine sawyer, notable sawyer
Monochamus notatus is a large longhorned beetle (Cerambycidae) native to North America, occurring in Canada and the United States east of the Rocky Mountains. Adults are active from late spring through summer and are attracted to dead and dying conifers, particularly pines. The species is notable for its pronounced sexual dimorphism: males possess antennae up to twice their body length and elongated forelegs with expanded tarsi, while females have shorter antennae and unmodified legs. Like other Monochamus species, it responds to the aggregation pheromone monochamol and male-produced 2-(undecyloxy)-ethanol for mate location.
Monochamus titillator
Southern Pine Sawyer
Monochamus titillator is a large longhorned beetle native to the United States, commonly known as the southern pine sawyer. Adults are notable for their elongated antennae, particularly in males, which may exceed body length. The species develops in pine trees and has been documented to respond to kairomones produced by bark beetles, suggesting ecological interactions with these forest pests. Larvae produce distinctive acoustic signals detectable in the 1000-2800 Hz range, a trait that has been explored for detecting southern pine beetle infestations.
