Anthophylax viridis
Green Flower Longhorn
Anthophylax viridis is a species of flower longhorn beetle in the subfamily Lepturinae. It is found in eastern North America, including the northeastern United States and southeastern Canada. Adults are associated with flowers and are known to visit a variety of blooming plants. The species is one of several in the genus Anthophylax, which are characterized by their flower-visiting behavior and relatively small size among longhorn beetles.
Asemum australe
Asemum australe is a species of longhorned beetle in the family Cerambycidae, described by John Lawrence LeConte in 1850. It is native to North America, with documented occurrences in the United States and Canada including Québec. The species has a brown, oval-shaped body. As a member of the genus Asemum, it belongs to a group of wood-boring beetles whose larvae develop in coniferous wood.
Brachysomida atra
Brachysomida atra is a species of longhorn beetle in the subfamily Lepturinae, described by John Lawrence LeConte in 1850. It occurs in western North America, with records from Alberta and British Columbia in Canada, and the United States. As a member of the Rhagiini tribe, it belongs to a group of flower-visiting longhorn beetles, though specific biological details for this species remain poorly documented.
Byrrhus americanus
pill beetle
Byrrhus americanus is a species of pill beetle in the family Byrrhidae, first described by John Lawrence LeConte in 1850. Pill beetles in this family are characterized by their rounded, compact body form that allows them to curl into a ball when disturbed—a defensive behavior that gives the group its common name. The species is recorded from North America with specific locality records from Canadian provinces including Labrador, Manitoba, and New Brunswick.
Dichelotarsus puberulus
Dichelotarsus puberulus is a species of soldier beetle in the family Cantharidae, first described by John Lawrence LeConte in 1850. The species is recorded from multiple Canadian provinces, suggesting a boreal or transcontinental distribution pattern. Like other members of Cantharidae, it is likely associated with vegetation and flowering plants where adults feed on pollen and small insects. The genus Dichelotarsus is characterized by particular antennal and tarsal structures that distinguish it from related genera.
Dichelotarsus punctatus
Dichelotarsus punctatus is a species of soldier beetle in the family Cantharidae, first described by John Lawrence LeConte in 1850. It is a small to medium-sized beetle found in eastern North America, where it inhabits forested and open habitats. Like other cantharids, it possesses soft, flexible elytra and is likely active during the warmer months, though specific biological details remain poorly documented.
Laccornis conoideus
Laccornis conoideus is a species of predaceous diving beetle in the family Dytiscidae. It is known from North America, with records from Alberta and British Columbia in Canada. As a member of the tribe Laccornini, it belongs to a group of small to medium-sized diving beetles. The species was first described by LeConte in 1850.
Lebia divisa
Lebia divisa is a species of ground beetle in the family Carabidae, first described by John Lawrence LeConte in 1850. It belongs to the diverse genus Lebia, commonly known as colorful foliage ground beetles, which are recognized for their small size and often bright metallic elytra. The species is documented from North America, with distribution records from both the United States and Canada. Like other members of its genus, it is likely associated with vegetation and may be attracted to lights at night.
Michthisoma heterodoxum
Michthisoma heterodoxum is a small cerambycid beetle in the tribe Saphanini, first described by LeConte in 1850. The species is known for its remarkable morphological resemblance to small workers of the carpenter ant Camponotus pennsylvanicus, representing a case of myrmecomorphy (ant mimicry). This mimicry appears to be an evolutionary adaptation to avoid predation. The species has a restricted geographic range, occurring primarily in the southeastern Coastal Plain of the United States. Despite its distinctive appearance, the species appears to be rarely encountered in the field.
Nephus ornatus
ornate lady beetle
Nephus ornatus is a small lady beetle species in the family Coccinellidae, commonly known as the ornate lady beetle. It is classified among the dusky lady beetles, a group characterized by generally subdued coloration compared to the brightly patterned lady beetles more familiar to the public. The species was described by John Lawrence LeConte in 1850 and is known to occur across North America.
Phyllophaga futilis
lesser June beetle
Phyllophaga futilis, commonly known as the lesser June beetle, is a species of scarab beetle in the family Scarabaeidae. It is found in North America, with distribution records spanning across the United States and southern Canada. Like other members of the genus Phyllophaga, it is commonly referred to as a May beetle or June beetle. The species is part of a large genus containing over 400 species in North America, many of which are difficult to distinguish without examination of genitalia.
Platycerus depressus
Aspen stag beetle (eastern)
Platycerus depressus is a species of stag beetle in the family Lucanidae, described by Joseph LeConte in 1850. It is one of the smaller stag beetles in North America and is associated with aspen and other deciduous trees. The species is widely distributed across boreal and temperate regions of Canada and the northern United States. It is commonly known as the eastern aspen stag beetle due to its association with Populus tremuloides and related host trees.
Priognathus
Priognathus is a genus of dead log beetles in the family Pythidae, established by LeConte in 1850. The genus contains a single described species, Priognathus monilicornis. Members of this genus are part of the small family Pythidae, which is associated with decaying wood habitats. Information on the biology and ecology of Priognathus remains limited due to its rarity and the scarcity of observations.
Saperda moesta
Saperda moesta is a species of longhorn beetle in the family Cerambycidae, described by LeConte in 1850. It belongs to the subfamily Lamiinae and tribe Saperdini. The species is recognized as valid by major taxonomic databases including GBIF and NCBI, though Catalogue of Life lists it as a synonym. Distribution records indicate presence in Canada and the contiguous United States.
Saperda moesta moesta
A North American subspecies of longhorn beetle in the family Cerambycidae. Adults are characterized by elongated bodies with exceptionally long antennae typical of the family. The subspecific status indicates geographic variation within the broader species Saperda moesta, which belongs to a genus known for wood-boring larvae that develop in living or stressed trees.
Silis difficilis
Hardy Soldier Beetle
Silis difficilis is a species of soldier beetle in the family Cantharidae, distributed across North America. The species was described by LeConte in 1850. Two subspecies are recognized: Silis difficilis difficilis and Silis difficilis flavida. Soldier beetles in this family are generally soft-bodied, predatory or omnivorous beetles commonly found on flowers and foliage.
Tylosis maculatus
Spotted Tylosis
Tylosis maculatus is a species of longhorn beetle in the family Cerambycidae, described by John Lawrence LeConte in 1850. It belongs to the tribe Trachyderini, a group known for often striking coloration patterns. The species is recognized by its spotted pattern, as indicated by its specific epithet 'maculatus'. It occurs in North and Middle America, with records from the United States and Mexico.
Tylosis oculatus
Tylosis oculatus is a species of longhorn beetle (Cerambycidae) described by John Lawrence LeConte in 1850. The specific epithet "oculatus" refers to eye-like markings, suggesting the species bears distinctive ocular patterns on its body. As a member of the subfamily Cerambycinae and tribe Trachyderini, it belongs to a group of robust, often strikingly marked longhorn beetles. The genus Tylosis is native to the Americas, with species distributed across North and Central America.
Xestoleptura tibialis
flower longhorn beetle
Xestoleptura tibialis is a species of flower longhorn beetle in the family Cerambycidae. It was originally described as Leptura tibialis by LeConte in 1850. The species is found across North America, with records from Canada including Alberta, British Columbia, Labrador, and Manitoba. As a member of the subfamily Lepturinae, it belongs to a group commonly known as flower longhorns that are frequently associated with flowering plants.
