Acentropini
China-mark moths
Acentropini is a tribe of aquatic moths within the family Crambidae, commonly known as china-mark moths. Adults are small to medium-sized moths with wingspans typically ranging from 15–35 mm. The tribe is distinguished by larvae that are fully aquatic, breathing through gills and feeding on submerged aquatic plants. These moths are found across temperate and tropical regions worldwide, with highest diversity in the Old World tropics.
Amphasia interstitialis
Red-headed Ground Beetle
Amphasia interstitialis, commonly known as the red-headed ground beetle, is a small ground beetle native to North America. Adults measure 8.5–10.2 mm and display distinctive coloration with dark elytra contrasting against an orange pronotum and head. The species occupies moist, covered microhabitats within deciduous forests, including leaf litter and spaces beneath stones and logs. It is widespread across the northeastern United States and adjacent Canadian provinces, with populations extending into the central United States.
Bibarrambla
bog bibarrambla moth (sole species)
Bibarrambla is a monotypic genus of moths in the family Depressariidae, containing only Bibarrambla allenella, commonly known as the bog bibarrambla moth. The genus was established by Clarke in 1941, though the sole species was described earlier by Walsingham in 1882. The species occurs in eastern and central North America, with larvae feeding on Alnus and Betula species.
Euphyes
grass skippers
Euphyes is a genus of grass skippers (Hesperiidae: Hesperiinae) comprising approximately 22 species distributed across North America, the Caribbean, and parts of Central America. Species are typically associated with wetland and grassland habitats, with larvae feeding on sedges (Cyperaceae) and other monocots. The genus includes several regional endemics and habitat specialists, some of conservation concern.
Odontomyia
soldier flies, brigadier flies
Odontomyia is a genus of soldier flies in the family Stratiomyidae. Species in this genus are characterized by distinctive color patterns, often with orange or yellow markings on dark backgrounds. The genus occurs across temperate and tropical regions of Europe, Asia, and the Americas. Larvae are aquatic, inhabiting ditches and other freshwater habitats. Some species serve as indicators of habitat quality in wetland ecosystems.
Plateumaris
spade reed beetles
Plateumaris is a genus of aquatic leaf beetles in the family Chrysomelidae, subfamily Donaciinae, distributed across the Holarctic region. The genus comprises approximately 27 species globally, with 17 described in North America and 10 in the Palaearctic. Adults are found along margins of water bodies on emergent aquatic plants, while larvae develop submerged on plant roots. Species are recognized by diagnostic morphological features including the lack of pubescence above the procoxa and rounded, declivous elytral apices with a sinuate sutural area. Females possess a strongly sclerotized, shovel-like ovipositor that often protrudes from the abdomen, giving rise to the common name "spade reed beetles".
Rhantus
Rhantus is a genus of predaceous diving beetles (Dytiscidae) comprising approximately 100 species with worldwide distribution. Members of this genus are primarily associated with lentic freshwater habitats, particularly pools and marshy wetlands. The genus is currently recognized as paraphyletic; taxonomic revision is anticipated following 2017 research that transferred 17 species to newly established genera (Nartus, Meridiorhantus, Caperhantus, and Carabdytes). Several species have independently colonized oceanic islands and undergone endemic diversification.
Sericomyia sexfasciata
Six-banded Pond Fly
Sericomyia sexfasciata is a species of syrphid fly (family Syrphidae) commonly known as the Six-banded Pond Fly. It belongs to the subfamily Eristalinae and tribe Milesiini. Like other members of its genus, the larvae develop in aquatic or semi-aquatic habitats. The species was first described by Francis Walker in 1849.
