Agrotis arenarius
Sable Island Cutworm Moth
Agrotis arenarius is a noctuid moth endemic to Sable Island, Nova Scotia, Canada. First described by Neil in 1983, this species is known from only a handful of observations. Its restricted distribution to a single small island makes it one of the most geographically limited Agrotis species. The specific epithet "arenarius" refers to the sandy habitat of its island home.
Atractotomus mali
Atractotomus mali is a zoophytophagous plant bug in the family Miridae, native to Europe and Northern Asia (excluding China) and introduced to North America. First described in 1843, it has become a recognized pest of apple (Malus domestica) in Canadian orchards, particularly in Nova Scotia where it was first documented causing fruit damage in the mid-20th century. The species was first recorded in Quebec in 2014, expanding its known Canadian distribution. Its feeding behavior combines plant and animal matter, though it has been observed causing more damage to fruit than providing predatory benefits in some orchard contexts.
Caloptilia canadensisella
Caloptilia canadensisella is a leaf-mining moth in the family Gracillariidae. It is known from eastern Canada, specifically Nova Scotia and Québec. The larvae feed on Cornus canadensis (bunchberry), creating mines in the leaves of this host plant. The species was described by James Halliday McDunnough in 1956.
Colladonus balius
Colladonus balius is a leafhopper species in the family Cicadellidae, described by Hamilton in 1987. It belongs to the tribe Platymetopiini within the subfamily Deltocephalinae. Like other members of its genus, it is a small, sap-feeding insect. The species has been recorded from Nova Scotia, Canada. Very little specific information is available about its biology or ecology.
Dalopius pennsylvanicus
Dalopius pennsylvanicus is a species of click beetle in the family Elateridae, first described by W.J. Brown in 1934. It belongs to a genus of small to medium-sized beetles characterized by the ability to right themselves when flipped using a specialized prosternal process that clicks against a mesosternal groove. The species has been documented in Nova Scotia, Canada.
Euvira
Euvira is a genus of rove beetles (Staphylinidae: Aleocharinae) established by Sharp in 1883. The genus was first recorded in Canada with the description of E. micmac from Nova Scotia, where specimens were found inhabiting red oak galls. At least one additional species, E. quadriceps (Casey), is known in the genus.
Gloeosoma hesperum
Gloeosoma hesperum is a minute beetle species in the family Corylophidae, a group commonly known as minute fungus beetles. First described by Casey in 1900, this species belongs to a genus characterized by extremely small body size and association with fungal substrates. The family Corylophidae is among the smallest beetles in North America, with most species measuring less than 2 mm in length. Records indicate presence in Nova Scotia, Canada, though detailed biological information remains sparse due to the cryptic habits and diminutive size of these insects.
Neoporus sulcipennis
Neoporus sulcipennis is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America.
Phloeocharinae
Phloeocharinae is a subfamily of rove beetles (Staphylinidae) characterized by distinctive abdominal tergal combs and procoxal morphology. The group contains five genera and six species in North America, with the genus Phloeocharis dominating the European fauna. Members are primarily saproxylic, inhabiting damp forest environments under bark and in leaf litter. The biology of most species remains poorly known.
Quedius spelaeus
Spelean Rove Beetle
A troglophilic rove beetle found in porcupine dung caves in Nova Scotia, where it functions as the dominant invertebrate predator. The pupal stage was described for the first time from Nova Scotian populations. Late-instar larvae excavate and occupy cavities within dung deposits, pupating in these constructed chambers. The species shows an apparently disjunct distribution pattern in Nova Scotia, possibly reflecting post-glacial colonization from Atlantic refugia.
