Ctenopelmatinae
Ctenopelmatinae is a cosmopolitan subfamily of ichneumonid wasps comprising approximately 95 genera of koinobiont endoparasitoids. Members are small to medium-sized wasps that primarily attack sawflies (Symphyta), with some species parasitizing Lepidoptera. The subfamily was historically classified within Tryphoninae but was separated based on larval morphology and ecological traits. Ctenopelmatines are particularly abundant in temperate Holarctic regions, where they can constitute over 10% of local ichneumonid faunas in cooler areas.

Ctenopelmatini
Ctenopelmatini is a tribe of ichneumonid wasps within the family Ichneumonidae. Members are parasitoid wasps whose larvae develop within or on host organisms. The tribe is characterized by specific morphological traits of the forewing venation and ctenopelmatine-type ovipositor structure. Ctenopelmatini species are primarily associated with sawfly hosts (Symphyta), distinguishing them ecologically from many other ichneumonid tribes. The tribe is relatively small and poorly documented compared to larger ichneumonid tribes.

Cynipoidea
Gall Wasps and Allies
Cynipoidea is a superfamily of small wasps comprising approximately 3,000 described species across seven extant families, with many undescribed species estimated. The group exhibits diverse life histories: while the family Cynipidae (gall wasps) are phytophagous and induce plant galls, the majority of species are parasitoids or hyperparasitoids of other insects. The superfamily is taxonomically challenging, with family-level identification historically difficult until the publication of a comprehensive illustrated key in 2020.

Cyphomyrmex
fungus-growing ants
Cyphomyrmex is a genus of small, drab-colored fungus-growing ants in the tribe Attini, found primarily in the Neotropics. These ants cultivate fungi in the tribe Leucocoprineae as their primary food source, with most species growing fungal nodules rather than full mycelial gardens. Colonies are typically monogynous and small, rarely exceeding 500 workers. The genus is divided into two species complexes: the strigatus complex (South America only) and the rimosus complex (southern North America to South America). Cyphomyrmex represents a basal lineage among attine ants and serves as sister group to Mycetophylax.

Dendroctonus simplex
Eastern Larch Beetle
Dendroctonus simplex, the eastern larch beetle, is a bark beetle in the family Curculionidae that colonizes the phloem of tamarack (Larix laricina). Historically a secondary pest attacking stressed or dying trees, it has undergone an unprecedented 18-year outbreak in northern Minnesota since 2000, killing over 440,000 acres of tamarack forest. Research indicates that warming climate has enabled some populations to complete development without an obligatory overwintering period, potentially allowing multiple generations per year. The beetle is a holobiont, engaging in multipartite symbiotic interactions with bacteria and fungi that facilitate host colonization and detoxification of terpenes.

Dendroctonus terebrans
Black Turpentine Beetle
Dendroctonus terebrans, the black turpentine beetle, is the largest bark beetle in the southeastern United States. It attacks pine trees near the base of the trunk and in stumps, typically targeting stressed or freshly cut trees. Unlike the more destructive southern pine beetle (D. frontalis), it rarely kills healthy trees outright but can contribute to tree mortality through sustained feeding damage and by vectoring blue-stain fungi. The species produces and responds to complex semiochemicals, including frontalin and brevicomin, which facilitate mass attack behavior and may mediate interactions with other bark beetle species.

European and North American species are solitary endoparasitoids of leaf-mining moth larvae in the genus Stigmella (Nepticulidae), while the biology of Asian species remains unknown. Two species groups have been established based on morphological differences: the gemmeus group (European and North American species) and the sulciscuta group (Asian species).

Derostenus freemani
Derostenus freemani is a species of parasitoid wasp in the family Eulophidae, first described from the Nearctic region in 1973. It is a solitary endoparasitoid of Stigmella larvae (Lepidoptera: Nepticulidae), minute moths commonly known as pygmy or midget moths. The species was originally placed in the subgenus Nearctostenus, though subsequent revision abandoned this subgeneric division in favor of species-group classification, placing D. freemani in the gemmeus group alongside European species.

Desmia funeralis
grape leaffolder, grape leaf-folder
Desmia funeralis, commonly known as the grape leaffolder, is a moth in the family Crambidae. It is a minor pest of grape vineyards across the United States, with larvae that feed on grape leaves, causing characteristic leaf folding or rolling damage. The species is widely distributed from the southern United States through California, extending north to the northeastern states and southeastern Canada. Severe outbreaks have occurred in localized areas, particularly when natural parasitoid populations fail to control moth numbers.

Diachasmimorpha
Diachasmimorpha is a genus of braconid parasitoid wasps in the subfamily Opiinae, established in 1913. The genus is most clearly defined by an apical sinuate ovipositor, a synapomorphic character that defines a monophyletic lineage. Species in this genus are solitary endoparasitoids of tephritid fruit fly larvae and are widely used as biological control agents in integrated pest management programs. The genus is relatively small and primarily distributed in subtropical regions, with some species extending into the Nearctic and northern Neotropical regions.

Diadegma
Diadegma is a genus of ichneumonid wasps established by Förster in 1869. Species in this genus are koinobiont parasitoids, primarily attacking lepidopteran larvae. Several species, notably D. insulare and D. semiclausum, have been extensively studied and deployed as biological control agents against agricultural pests, particularly the diamondback moth (Plutella xylostella). The genus contains over 200 described species with cosmopolitan distribution.
