Clinohelea bimaculata
(Loew, 1861)
Bimaculata Group
Clinohelea bimaculata is a of in the , first described by Loew in 1861. It belongs to a diverse family of tiny commonly known as , , or biting midges. The species has been documented in North America, with photographic records from Kansas. Like other ceratopogonids, it is extremely small and presents significant challenges for observation and identification.

Identification
Clinohelea bimaculata can be distinguished from similar ceratopogonids by its , patterned appearance and relatively slender body form compared to the more . The specific epithet "bimaculata" (two-spotted) likely refers to distinctive markings on the body or . Identification to species level typically requires examination of microscopic features including , antennal structure, and . The Clinohelea is characterized by particular antennal and palpal features that separate it from related genera within the tribe Heteromyiini.
Habitat
Based on documented observations, Clinohelea bimaculata has been found on leaf surfaces in terrestrial environments. As with most , likely develop in moist microhabitats such as soil, decaying matter, or other humid substrates.
Distribution
North America. Documented from Leavenworth, Kansas, USA based on photographic record. The ' broader distribution within North America requires further documentation.
Behavior
have been observed resting on leaf surfaces. Males of many form aerial swarms for mating, though this specific has not been documented for C. bimaculata. Both sexes of ceratopogonids typically feed on nectar and sugary liquids.
Ecological Role
As a member of the , this likely participates in through larval feeding on matter or , and may serve as for larger and other organisms. The includes species that function as , agents, and .
Human Relevance
No specific economic or medical importance has been documented for this . Unlike some species, Clinohelea species are not known as significant pests of humans or livestock.
Similar Taxa
- Culicoides spp.Both are , but are generally more , have different patterns, and are known for biting humans and livestock. Clinohelea species tend to be more slender and ornately patterned.
- Forcipomyia spp.Both belong to and share small size, but Forcipomyia often have distinctive leg modifications and different ecological associations, including the well-known cacao Forcipomyia spp.
- Other Clinohelea speciesCongeneric share similar body plans and antennal structures, requiring detailed examination of and other microscopic features for definitive identification.
