Neoporus vitiosus
Neoporus vitiosus is a small predaceous diving beetle in the family Dytiscidae, subfamily Hydroporinae. The species was described by LeConte in 1855 and is documented from North America, with specific records from Ontario and Québec in Canada. As a member of the Hydroporinae, it likely inhabits freshwater environments, though detailed ecological studies are limited.

Horn's Predaceous Diving Beetle
Neoscutopterus hornii is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America, with distribution records from Alberta and British Columbia in Canada. The species was described by Crotch in 1873. As a member of the predaceous diving beetles, it is an aquatic predator, though specific ecological details remain poorly documented in the available literature.

Oreodytes alaskanus
Oreodytes alaskanus is a small predaceous diving beetle in the family Dytiscidae, first described by Fall in 1926. It belongs to the subfamily Hydroporinae, one of the most diverse lineages of diving beetles. The species is associated with freshwater habitats in northern North America.

Oreodytes humboldtensis
Oreodytes humboldtensis is a species of predaceous diving beetle in the family Dytiscidae, described by Zimmerman in 1985. As a member of the genus Oreodytes, it belongs to a group of small diving beetles primarily associated with running water habitats. The species epithet suggests a connection to the Humboldt region, likely referring to Humboldt County or the broader Humboldt Bay area of coastal northern California. Like other Oreodytes species, it is presumed to be an aquatic predator in freshwater systems.

Oreodytes laevis
Oreodytes laevis is a species of predaceous diving beetle in the family Dytiscidae. It is distributed across North America, with records from Canada (Alberta, British Columbia) and the United States. As a member of the Hydroporinae subfamily, it inhabits aquatic environments where it functions as an active predator.

Oreodytes snoqualmie
Oreodytes snoqualmie is a species of predaceous diving beetle in the family Dytiscidae. It was described by Hatch in 1933 and was originally placed in the genus Hydroporus. The species is known from western North America, with records from Alberta and British Columbia in Canada. As a member of the genus Oreodytes, it belongs to a group of small diving beetles typically associated with lotic (flowing water) habitats.

Phidippus cardinalis
cardinal jumper
Phidippus cardinalis is a jumping spider in the family Salticidae, commonly known as the cardinal jumper. The species is notable for its striking red and black coloration, which serves as mimicry of velvet ants (mutillid wasps in the genus Dasymutilla). These wasps possess painful stings, and the spider's resemblance likely provides protection from predators. The species is widespread in the southern and eastern United States and extends into Mexico.

Rhantus sericans
Rhantus sericans is a predaceous diving beetle in the family Dytiscidae, first described by Sharp in 1882. The species is distributed across North America and has been recorded from the Holarctic region, including the Canadian province of Alberta. As a member of the genus Rhantus, it belongs to a group of diving beetles adapted to aquatic environments. The species is represented by 88 observations on iNaturalist, indicating it is documented but not exceptionally common in citizen science records.
