There are approximately 2500 species of mosquitoes across the world and roughly 82 of those species can be found here in Canada. One mosquito species of particular interest is the Coquillettidia perturbans, aka the “cattail mosquito”. Aside from being a major nuisance, the cattail mosquitoes are vectors for many diseases, including West Nile virus, and Eastern equine encephalomyelitis, among others.
