19 October 2018 – La Crosse virus (LACV) and Eastern Equine encephalitis virus (EEEV) are arthropod borne (arbo-) viruses that can be deadly. LACV is vectored by small mammal biting tree-hole mosquitoes, Aedes triseriatus, but invasive Ae. albopictus and, up in the Adirondacks, Ae. japonicus another invasive, have become abundant vectors willing to bite humans. EEEV with a 33% mortality rate is vectored by bird-biting black tailed mosquitoes, Culiseta melanura, a species that lays eggs in cool, acidic water with a pH close to 5.0 along the edges of swamps, flood plains and woodland pools.
