Ampedus sanguinipennis
Ampedus sanguinipennis is a click beetle in the family Elateridae, native to eastern North America. The species name "sanguinipennis" refers to the blood-red wing coloration characteristic of this beetle. It is one of numerous Ampedus species distinguished by bright coloration, often in red or orange tones. Records indicate presence in eastern Canada and the northeastern United States.
Anthrax irroratus
Spotted Bee Fly
Anthrax irroratus is a bee fly (family Bombyliidae) widespread across North America, ranging from Alaska and northern Canada to Central America and the Caribbean. Adults are pollinators that frequent flowers, while larvae are parasitoids of solitary bees and wasps in at least five families. The species is one of numerous bee flies that exploit ground-nesting Hymenoptera as hosts.

Geodromicus brunneus is a species of rove beetle in the family Staphylinidae, subfamily Omaliinae. It is native to eastern North America, with documented records from Canada and the United States. The species was originally described by Thomas Say in 1823. Like other members of the genus Geodromicus, it is a ground-dwelling beetle typically found in forest floor habitats.
Harpalus faunus
Harpalus faunus is a species of ground beetle in the subfamily Harpalinae, first described by Thomas Say in 1823. It belongs to the large and diverse genus Harpalus, which contains numerous species across North America and other regions. Like other members of its genus, it is a ground-dwelling predator that inhabits open terrestrial environments. The species has been recorded from Canada and the United States, with observations documented in the northern parts of its range.
Harpalus herbivagus
Harpalus herbivagus is a ground beetle species in the family Carabidae, subfamily Harpalinae. First described by Thomas Say in 1823, this species is native to North America with documented occurrence in Canada and the United States. Like other members of the genus Harpalus, it is a ground-dwelling beetle typically found in terrestrial habitats. The species name 'herbivagus' suggests herbivorous or plant-associated feeding habits, though specific ecological details remain poorly documented.
Isorhipis ruficornis
false click beetle
Isorhipis ruficornis is a species of false click beetle in the family Eucnemidae. The species was described by Thomas Say in 1823. It is one of several North American species in the genus Isorhipis, which are being actively revised by entomologists. The specific epithet "ruficornis" refers to the reddish coloration of the antennae.
Lebia ornata
colorful foliage ground beetle
A small ground beetle in the genus Lebia, described by Thomas Say in 1823. The genus is known for its often bright metallic coloration. The species has a broad distribution across eastern North America, ranging from Texas and South Dakota east to Nova Scotia and south to Florida.
Leucotabanus annulatus
Leucotabanus annulatus is a species of horse fly in the family Tabanidae. It belongs to the tribe Diachlorini within the subfamily Tabaninae. The species was described by Thomas Say in 1823. It is found in the United States, though specific details about its biology and ecology remain poorly documented in available sources.
Loxocera cylindrica
rust fly
Loxocera cylindrica is a species of rust fly in the family Psilidae, first described by Thomas Say in 1823. It is one of the most frequently observed species in its genus, with over 1,100 documented observations on iNaturalist. The species belongs to a family commonly known as rust flies, though specific ecological details for this particular species remain limited in published literature.
Neoporus undulatus
Neoporus undulatus is a predaceous diving beetle in the family Dytiscidae. It is found in North America, with records from Canada (Alberta, British Columbia) and the United States. The species was first described by Thomas Say in 1823. As a member of the Hydroporinae subfamily, it belongs to a diverse group of small to medium-sized diving beetles that inhabit aquatic environments.
Pilaria tenuipes
Pilaria tenuipes is a crane fly in the family Limoniidae, first described by Thomas Say in 1823 under the name Limnobia tenuipes. It is a small, delicate nematoceran fly distributed across much of North America. The species is one of approximately 400 species in the genus Pilaria, which are typically associated with moist habitats. Despite its wide distribution, detailed biological information remains limited.
Pterostichus caudicalis
Pterostichus caudicalis is a species of ground beetle in the family Carabidae, described by Thomas Say in 1823. It is classified as a woodland ground beetle and occurs in North America, with distribution records from Canada and the United States. Like other members of the genus Pterostichus, it is a predatory beetle that inhabits forest floor environments. The species is part of the diverse Pterostichinae subfamily, which contains numerous ground-dwelling carabid beetles.
Sericoda obsoleta
Sericoda obsoleta is a species of ground beetle in the family Carabidae, occurring in North America. It is one of several species in the genus Sericoda, which are generally associated with riparian and wetland habitats. The species was described by Thomas Say in 1823. Available information on this species is limited, with most sources providing only basic taxonomic and distributional data.
Tabanus molestus
horse fly
Tabanus molestus is a species of horse fly in the family Tabanidae, first described by Thomas Say in 1823. It is distributed in the United States. Like other horse flies, females possess blade-like mouthparts adapted for cutting skin to obtain blood meals, while males have reduced mouthparts and do not blood feed. The species is part of the diverse genus Tabanus, which includes some of the largest biting flies in North America.
Thyreodon atricolor flavicornis
Thyreodon atricolor flavicornis is a subspecies of ichneumon wasp in the family Ichneumonidae, first described by Thomas Say in 1823.
