Ochlerotatus hendersoni
Cockerell, 1918
Ochlerotatus hendersoni is a mosquito closely related to Ochlerotatus triseriatus, with which it can produce viable interspecific hybrids. Unlike its O. triseriatus, which is an efficient for La Crosse virus, O. hendersoni transmits this virus only at very low rates. Genetic studies have identified quantitative trait loci associated with this refractory , with some regions containing genes from O. hendersoni that paradoxically increase transmission ability in hybrid offspring, likely due to epistatic interactions. The species is present in North America, including the northeastern United States.

Identification
Distinguished from the closely related Ochlerotatus triseriatus through genetic and morphological analysis; the two produce viable F2 hybrid offspring. Specific diagnostic morphological features are not documented in available sources. for La Crosse virus provides a functional distinction, though this requires laboratory testing.
Distribution
North America, including the northeastern United States (Vermont documented). Europe and Northern Asia (excluding China) listed as present in GBIF, though this may reflect taxonomic confusion or misidentification given the ' known North range.
Human Relevance
Low for La Crosse virus, a leading cause of pediatric in the United States, makes this of limited epidemiological concern compared to its O. triseriatus. Genetic studies of this species inform understanding of mosquito vector competence evolution.
