Dialytodius
Dialytodius is a genus of scarab beetles in the family Scarabaeidae, subfamily Aphodiinae. The genus was established by Gordon and Skelley in 2007. It belongs to the tribe Aphodiini and is currently recognized as valid. Species in this genus are part of the diverse aphodiine dung beetle fauna of the Nearctic region.

Diapterna
Diapterna is a genus of aphodiine dung beetles in the family Scarabaeidae, established by Horn in 1887. The genus contains six described species distributed across the Nearctic and Neotropical regions. Species in this genus are small to medium-sized scarab beetles associated with dung and decaying organic matter. Like other aphodiines, they are classified as 'dwellers' that feed and reproduce within dung rather than constructing tunnels.

Diatraea
sugarcane borer, stalk borer
Diatraea is a genus of moths in the family Crambidae comprising approximately 40 described species. The genus is best known for several economically important stalk-boring pests of grass crops, particularly sugarcane, corn, sorghum, and rice. Larvae tunnel within plant stems, causing reduced yield, lodging, and increased susceptibility to pathogens. Several species have been the focus of extensive biological control programs, notably using parasitoid wasps such as Cotesia flavipes and Trichogramma galloi. The genus is distributed throughout the Americas from the southern United States to Argentina.

Dicerca callosa frosti
Dicerca callosa frosti is a subspecies of jewel beetle in the family Buprestidae. Originally described as Dicerca frosti by Nelson in 1963, it was later synonymized or treated as a subspecies of D. callosa. The species epithet "frosti" honors a collector, following common practice in buprestid taxonomy. Like other Dicerca species, it is a woodboring beetle with cryptic coloration that provides camouflage against bark.

Dienerella filiformis
Slender plaster beetle
Dienerella filiformis is a minute beetle in the family Latridiidae, commonly known as plaster beetles due to their association with damp, moldy environments. The species is characterized by its notably slender, elongated body form compared to congeners. It has been recorded across eastern Canada, with distribution spanning from Manitoba to the Maritimes. Like other members of the genus, it is presumed to feed on fungal hyphae and spores in humid microhabitats.

Diogmites
Hanging Thieves
Diogmites is a genus of medium to large robber flies (17–48 mm) in the family Asilidae, commonly known as "Hanging Thieves" for their distinctive feeding posture. The genus contains 73–77 recognized species distributed mainly in the Neotropics, with some species extending into the Nearctic region. Adults are ambush predators that capture flying or perching insects and feed while suspended from vegetation by their front legs. The genus is characterized by relatively long legs, a flexible prosternum that facilitates the hanging posture, and often striking green or iridescent eye coloration in live specimens.
