A Nearctic drosophilid fruit fly native to eastern United States forests. It has established as an invasive species in Europe since its discovery in former Czechoslovakia in 1975, subsequently spreading to Switzerland, Italy, and German border regions. The species exhibits a distinctive ecological strategy: breeding in damaged or parasitized nuts and fruits rather than relying solely on fermenting substrates. This behavioral constancy for interspecies dependency—exploiting substrates pre-conditioned by other insects—has enabled it to occupy a vacant niche in European ecosystems.
Chymomyza procnemoides

It occurs naturally in Korea and Japan and has been introduced to parts of Europe, including Switzerland and Germany, though some European records are marked as doubtful. The species belongs to a genus that includes several cave-dwelling species, though specific habitat details for C. japonica itself are limited in available sources.
Cinara costata
Mealy Spruce Aphid
Cinara costata is a large aphid species in the family Aphididae, commonly known as the Mealy Spruce Aphid. It feeds on conifers, particularly spruce (Picea spp.), and is native to Europe where it has been documented in Great Britain, Denmark, Belgium, and France. Like other Cinara species, it produces honeydew that attracts ants and wasps. The species was first described by Zetterstedt in 1828 from specimens collected in Scandinavia.
Cinara pilicornis

Cinara pilicornis is a large aphid species specialized on spruce trees, particularly Norway spruce (Picea abies) and Sitka spruce (Picea sitchensis). Native to Europe, it has been introduced to New Zealand and South Korea. The species produces melezitose, a trisaccharide sugar, and is associated with specific semiochemicals including nepetalactone compounds. It is attended by ants such as Formica polyctena and serves as a host for Entomophthora fungi, though it experiences low parasitism by the wasp Pauesia pini.

The genus has been documented across Europe and parts of Asia.
Cnemogonus
minute seed weevils
Cnemogonus is a genus of small weevils in the family Curculionidae, established by LeConte in 1876. The genus comprises approximately five described species distributed primarily in North America and Europe. These beetles are commonly referred to as minute seed weevils, reflecting their small body size and likely association with seeds as a food source. The genus includes the notable species Cnemogonus epilobii, which has been associated with willowherb plants (Epilobium).
Coelinius
Coelinius is a genus of parasitoid wasps in the family Braconidae, first described by Nees in 1818. Members of this genus are koinobiont endoparasitoids, meaning they develop inside living hosts without immediately killing them. The genus is part of the diverse ichneumonoid wasp fauna and contributes to biological control of host populations. Records indicate presence in northern European regions.
Coenomyia ferruginea
Stink Fly
Coenomyia ferruginea, commonly known as the stink fly, is a species of fly in the family Xylophagidae. The family name derives from Greek roots meaning "wood-eating," referring to the larval habit of developing in dead and decaying wood. Adults are large, brown, and slow-moving flies that can be mistaken for beetles at first glance. The species occurs across Europe and North America. Formerly classified as a subfamily of Rhagionidae (snipe flies), Xylophagidae is now recognized as a distinct family closely related to Tabanidae (horse and deer flies).

Coptodisca juglandiella is a Nearctic leafminer moth in the family Heliozelidae, first described by Chambers in 1874. Native to North America, it was discovered in Hungary in 2019 as a new invasive species for Europe. The larvae feed internally on walnut leaves, creating distinctive blotch mines. Unlike its congener C. lucifluella, it has not undergone a host plant shift since introduction to Europe.
Corticaria serrata
Serrated Minute Scavenger Beetle
Corticaria serrata is a species of minute brown scavenger beetle in the family Latridiidae. The species is native to Europe and has been recorded from the Azores and Inaccessible Island. Adults are small, typically measuring 2-3 mm in length. The species belongs to a group commonly known as plaster beetles or fungus beetles due to their association with mold and decaying organic matter.
Corticarina minuta
Minute plaster beetle
Corticarina minuta is a minute beetle in the family Latridiidae, commonly known as plaster beetles. The species was described by Fabricius in 1792 and is among the smallest beetles in this family, typically measuring less than 2 mm in length. It is associated with damp, moldy environments where it feeds on fungal growth. The species has been recorded across parts of Europe including Switzerland, Denmark, Norway, and Sweden.
Corylobium
Corylobium is a genus of aphids in the family Aphididae, established by Mordvilko in 1914. The genus is known from Europe, with distribution records from Denmark, Norway, and Sweden. At least one species, Corylobium avellanae, has been described. As members of Aphididae, these are sap-feeding insects.
Corythucha arcuata
oak lace bug
Corythucha arcuata, the oak lace bug, is a small sap-sucking insect in the family Tingidae native to North America. First detected in Europe in 2000, it has become a major invasive pest across more than 20 EU countries, causing significant damage to oak forests. The species overwinters as adults and produces multiple overlapping generations per year, with development rates and generation number determined by thermal accumulation. In its invaded range, it lacks effective natural enemies, prompting investigation of classical biological control using the egg parasitoid Erythmelus klopomor from its native range.
Crumomyia
Crumomyia is a genus of small flies in the family Sphaeroceridae, commonly known as lesser dung flies. Species in this genus have been documented from caves in Europe, including a troglophilous population in the Czech Republic that shows morphological adaptations to subterranean life.

The species exhibits a monoecious holocyclic life cycle with sexual morphs produced in fall for overwintering eggs and no summer host alternation.
Cucullia umbratica
shark moth
Cucullia umbratica, commonly known as the shark moth, is a noctuid moth first described by Linnaeus in 1758. The species is widely distributed across Europe and has been recorded in North America.

Cyclosa conica
Conical Trashline Orbweaver
Cyclosa conica is a small orb-weaving spider known for constructing distinctive vertical webs decorated with debris. Females measure 5.3–7.5 mm in body length, while males are smaller at 3.6–4 mm. The species is recognized by its unique behavior of stringing dead insect bodies and other debris vertically through the center of its web, forming a 'trashline' or stabilimentum. The spider positions itself at the hub of this debris, relying on its cryptic coloration to blend in and avoid detection by predators. When disturbed, it feigns death as a secondary defense.
Cydalima
Cydalima is a genus of moths in the family Crambidae, subfamily Spilomelinae. The genus contains approximately nine described species, with Cydalima perspectalis (box tree moth) being the most economically and ecologically significant due to its invasive status in Europe and North America. Most species in the genus are native to Asia, with limited documented information available for the majority of species beyond taxonomic descriptions.
Cydia nigricana
Pea Moth
Cydia nigricana, commonly known as the pea moth, is a small tortricid moth native to Europe and introduced to North America. The species is a significant agricultural pest whose larvae develop inside pea pods, feeding on developing seeds. Adults emerge from overwintering cocoons in early summer and are monitored using pheromone traps for integrated pest management. The species exhibits strong male response to synthetic sex pheromone, with peak flight activity occurring in late afternoon and evening hours.
