Spilomena occidentalis is a species of solitary aphid wasp in the family Crabronidae (subfamily Pemphredoninae). It was described by R. Bohart in 1995. The species is known from North America, with records from Canada including Alberta. Like other members of its genus, it is a predator of aphids, provisioning its nests with paralyzed prey for its larvae.
Tenuiphantes zebra
Zebra Thin Sheetweaver
Tenuiphantes zebra is a species of sheetweb spider in the family Linyphiidae, a group known for constructing flat, horizontal webs. First described by Emerton in 1882, this small spider is found in North America, with records from the United States and Canada. As a member of the dwarf spider family Linyphiidae, it contributes to terrestrial arthropod diversity in its range, though detailed ecological studies remain limited.
Timarcha intricata
Intricate Leaf Beetle
Timarcha intricata is a species of leaf beetle in the family Chrysomelidae, first described by Haldeman in 1853. It is found in North America, with distribution records from Canada (Alberta and British Columbia) and the United States. The species is commonly known as the Intricate Leaf Beetle. Like other members of the genus Timarcha, it belongs to a group of leaf beetles that are primarily associated with feeding on plant foliage.
Trichalophus alternatus
Trichalophus alternatus is a species of broad-nosed weevil in the family Curculionidae, first described by Say in 1831. It is a member of the subfamily Entiminae, which comprises the so-called 'true' weevils characterized by their elongated snouts. The species has been documented across western North America from Alaska to Colorado.
Tricholochmaea cavicollis
Cherry leaf beetle
Tricholochmaea cavicollis, known as the cherry leaf beetle, is a skeletonizing leaf beetle in the family Chrysomelidae. The species occurs across North America, with records from western and central Canadian provinces including Alberta, British Columbia, and Manitoba. As a member of the skeletonizing leaf beetle group, it feeds on leaf tissue between veins.
Trichordestra liquida
cutworm moth, dart moth
Trichordestra liquida is a species of cutworm or dart moth in the family Noctuidae. It occurs in North America, with distribution records from Alberta and Saskatchewan in Canada. The species was described by Grote in 1881 and is assigned MONA/Hodges number 10308.
Triplax cuneata
Triplax cuneata is a species of pleasing fungus beetle in the family Erotylidae, described by Boyle in 1954. The genus Triplax comprises small beetles associated with fungi, particularly mushrooms and polypores. T. cuneata has been recorded from western North America including the Canadian provinces of Alberta and British Columbia. Like other members of its genus, it likely inhabits fungal fruiting bodies where it feeds and reproduces.
Tychius tectus
leguminous seed weevil
Tychius tectus is a species of leguminous seed weevil in the family Curculionidae, first described by LeConte in 1876 from North America. The species has been recorded from both North America and China, representing a transcontinental distribution pattern within the Holarctic region. As a member of the genus Tychius, it belongs to a group of weevils specialized on leguminous plants (Fabaceae). No specific biological or ecological studies have been published for this species.
Tymnes oregonensis
Oregon Leaf Beetle
Tymnes oregonensis is a species of leaf beetle in the family Chrysomelidae, tribe Alticini. It is native to western North America. The species was originally described by Crotch in 1873 and has been historically treated under the genus Phyllotreta as a synonym. Available records indicate presence in the Canadian provinces of Alberta and Manitoba, with broader distribution across North America. Like other members of the Alticini, it possesses enlarged hind femora adapted for jumping.
Xenochodaeus luscinus
Xenochodaeus luscinus is a species of sand-loving scarab beetle in the family Ochodaeidae. It was described by Howden in 1968. The species is known from western Canada, specifically Alberta and British Columbia. Like other members of its family, it is associated with sandy habitats.
Xestia plebeia
Xestia plebeia is a species of owlet moth in the family Noctuidae, described by Smith in 1898. The species was originally described under the genus Noctua before being transferred to Xestia. It has been recorded from Alberta, Canada. The genus placement has been subject to taxonomic discussion, with some treatments considering it related to or potentially synonymous with Hemigraphiphora.
Xylena thoracica
Acadian Swordgrass Moth
Xylena thoracica, commonly known as the Acadian Swordgrass Moth, is a species of cutworm moth in the family Noctuidae. It is found in North America, with records from Canada (Alberta, Manitoba, Saskatchewan) and the United States (Vermont). The species was first described by Putnam-Cramer in 1886 and is assigned Hodges number 9875.
Xysticus gulosus
Xysticus gulosus is a species of crab spider in the family Thomisidae, described by Keyserling in 1880. It belongs to the genus Xysticus, a diverse group of ground-dwelling ambush predators commonly known as ground crab spiders. The species is distributed across North America, with confirmed records from the Canadian provinces of Alberta, Manitoba, and Saskatchewan. Like other members of its genus, it likely employs a sit-and-wait hunting strategy, using its enlarged front legs to capture prey.
Zenodoxus sidalceae
Zenodoxus sidalceae is a clearwing moth in the family Sesiidae, described by Engelhardt in 1946. The species epithet 'sidalceae' suggests a likely association with plants in the genus Sidalcea (mallow family, Malvaceae), though this relationship requires confirmation. As a member of the Tinthiinae subfamily, it belongs to a group of sesiid moths often characterized by wasp-mimicking appearance and diurnal activity. The species is poorly known, with limited observational records.
