trifasciata nassauensis
Dielis trifasciata nassauensis is a subspecies of scoliid wasp in the family Scoliidae. Scoliid wasps are large-bodied parasitoid wasps whose larvae develop as parasitoids of scarab beetle grubs. The genus Dielis has been inferred to be non-monophyletic in phylogenetic studies using ultraconserved element data. This subspecies is part of a group whose taxonomy has historically been unstable and is currently under revision based on modern systematic approaches.
Diglyphus pulchripes
Diglyphus pulchripes is a species of parasitoid wasp in the family Eulophidae. It belongs to a group of tiny wasps known as jewel wasps or pteromalids, which are characterized by their parasitoid life history where immature stages develop inside host insects, eventually killing the host. The species has been documented in Canada across multiple provinces. Like other members of its genus, it likely parasitizes leaf-mining insects, though specific host associations for this species require further documentation.
Diglyphus websteri
Diglyphus websteri is a tiny parasitoid wasp in the family Eulophidae. It belongs to a genus known for biological control of leafmining insects. The species has been documented in laboratory settings for parasitoid research.
Dilophotopsis
Dilophotopsis is a genus of velvet ants (Mutillidae) in the order Hymenoptera. The genus was established by Schuster in 1958. As with other mutillids, members are solitary wasps with wingless females and winged males. One species, D. concolor crassa, has been documented with host associations.
Dimorphopteryx melanognathus
fringed birch sawfly
Dimorphopteryx melanognathus is a species of sawfly in the family Tenthredinidae, commonly known as the fringed birch sawfly. It belongs to a genus characterized by distinctive wing morphology. The species has been documented from very few observations, indicating it may be rare, locally distributed, or underreported.
Dimorphopteryx pinguis
Dimorphopteryx pinguis is a species of sawfly in the family Tenthredinidae. The genus name Dimorphopteryx refers to the presence of two distinct wing forms in related species, though specific details for D. pinguis remain poorly documented. Very little is known about this species beyond its taxonomic placement.
Dineura
Dineura is a genus of sawflies in the family Tenthredinidae. Species occur in the West Palaearctic, Easternmost Asia, and North America. The genus contains at least four recognized West Palaearctic species, with taxonomic revisions clarifying species boundaries and synonymies. Reproductive behavior has been studied in D. virididorsata, which exhibits arrhenotokous parthenogenesis.
Dioxys productus
Dioxys productus is a species of solitary bee in the family Megachilidae, tribe Dioxyini. The species was described by Cresson in 1879 and is known from North America and Middle America. Members of the genus Dioxys are cleptoparasitic bees that lay their eggs in the nests of other megachilid bees.
Dipara trilineata
Dipara trilineata is a parasitoid wasp in family Diparidae endemic to eastern North America. Females are flightless (apterous) while males possess wings, creating pronounced sexual dimorphism. Despite this apparent dispersal limitation, populations across southern Appalachia show minimal genetic structure. The species was described from Trimicrops trilineatus in 1977, and its male had been misattributed until DNA barcoding definitively established the correct association.
Diplolepididae
rose gall wasps
Diplolepididae is a small family of gall-inducing wasps in the order Hymenoptera, recently elevated from tribe status within Cynipidae based on genetic and morphological evidence. The family comprises two subfamilies: Diplolepidinae (~60 species in Diplolepis and Liebelia) which induce galls exclusively on roses (Rosa), and Pediaspidinae (two monotypic genera: Himalocynips and Pediaspis) with poorly known biology, though Pediaspis aceris has been observed inducing galls on maple. These wasps are found in temperate regions across the Northern Hemisphere including Europe, Asia, and North America.
Diplolepis gracilis
Diplolepis gracilis is a species of gall wasp in the family Diplolepididae, first described by Ashmead in 1897. Like other members of its genus, it induces the formation of galls on host plants, likely within the rose family (Rosaceae) given the genus's strong association with this plant group. The species is recorded from multiple provinces across Canada including Alberta, British Columbia, Manitoba, and Ontario. As with most Diplolepis species, it exhibits a complex life cycle involving an alternation between sexual and parthenogenetic generations.
Diplolepis ignota
gall wasp
Diplolepis ignota is a gall wasp in the family Cynipidae that induces spherical, single-chambered galls on the leaves of wild rose species (Rosa). The galls serve as both shelter and food source for developing larvae. Multiple galls frequently coalesce into irregularly rounded clusters. Adults emerge from galls the summer following gall initiation. The species has been reported throughout most of the continental United States and in parts of central Canada.
Diploplectron ferrugineum
Diploplectron ferrugineum is a solitary wasp species in the family Crabronidae, subfamily Astatinae. It is a small, rust-colored wasp found in North America. Members of this genus are known to be ground-nesting predators that provision their nests with paralyzed prey, typically small insects. The species was described by William Harris Ashmead in 1899.
Dipogon
spider wasps
Dipogon is a genus of small spider wasps (Pompilidae) characterized by ant-mimicking dark-banded wings and a distinctive 'beard' of hairs on the maxillary palps used to transport nesting materials. These solitary wasps are primarily forest-dwelling, hunting spiders on tree trunks and constructing multi-celled nests in pre-existing tubular cavities such as beetle tunnels or hollow plant stems. The genus exhibits notable behavioral plasticity in nest construction, using mud, leaf fragments, insect parts, and even stolen bee provisions to form cell partitions.
Dipogon graenicheri
Dipogon graenicheri is a species of spider wasp in the family Pompilidae, described by Nathan Banks in 1939. The genus Dipogon comprises small, ant-mimicking wasps that hunt spiders on tree trunks and construct nests in pre-existing cavities. Species in this genus are rarely observed due to their cryptic appearance and arboreal foraging habits.
Diprion
conifer sawflies, pine sawflies
Diprion is a genus of conifer sawflies in the family Diprionidae, containing at least 12 described species. Species in this genus are significant defoliators of pine forests, with larvae feeding gregariously on pine needles. Outbreaks can cause substantial ecological and economic damage by defoliating thousands of forested acres. Adults are stingless wasps with a saw-like ovipositor used to insert eggs into conifer foliage. The genus includes both native and invasive species, with Diprion similis introduced to North America in 1914.
Diprion similis
Introduced Pine Sawfly, Imported Pine Sawfly, White Pine Sawfly
Diprion similis is a conifer-feeding sawfly native to central and northern Europe and Asia that has become invasive in North America following its accidental introduction around 1914. The species is notable for its arrhenotokous reproduction, where unfertilized eggs develop into male offspring, facilitating rapid population establishment. Larvae are gregarious defoliators of pine needles, with a strong preference for white pine (Pinus strobus) in North America. The species exhibits two generations per year in many regions, with second-generation larvae overwintering as prepupae in cocoons. Its invasive success has been attributed to parthenogenetic capabilities, lack of natural enemies in introduced ranges, and specialized pheromone communication involving the (2S,3R,7R)-propionate isomer of 3,7-dimethylpentadecan-2-ol.
