The Aedes infirmatus mosquito also know as the Woodland Mosquito or the Silverback mosquito which are mostly found in Atlantic coast and southern states from Texas across to Miami Florida and up to New Jersey. Their does not seem to be very much entomological data like there is for aedes aegypti and aedes albopictus. Dyar and Knab (1906) describe identification from larvae that had been collected at Baton Rouge, Louisiana. The larvae and adults were described in more detail later (Howard, Dyar and Knab, 1917, Vol. 4). As with most aedes species the populations will typically peak in the Summer or Fall, usually after large rain falls, the larvae is found in woodland pools and woodland ditches, Tree holes, Rock Pools, and Artificial Containers as Larval Habitats, in temporary rain pools found in wooded areas and open fields. , and move through the cool, shaded woodland areas.
Known Facts About Aedes infirmatus

They can be a bridge-vector of West Nile Virus WNV or Easter Equine Encephalitis EEEV and nd Guatemala (Scherer et al. 1972).
From the study ARBOVIRUSES ASSOCIATED WITH MOSQUITOES FROM NINE FLORIDA COUNTIES DURING 1993 C. J. MITCHELL,IJ C. D. MORRIS,’ G. C. SMITH,’ N. KARABATSOS,I D. VANLANDINGHAMI AND E. CODY, Two bunyaviruses isolated trivittatus Virus TVT and Keystone Virus KEY, are cycled between mammalian hosts and Aedes mosquitoes. In Florida, TVT virus has been most frequently associated with Aedes infirmatus. https://www.biodiversitylibrary.org/content/part/JAMCA/JAMCA_V12_N2_P255-262.pdf
Aedes infirmatus are very similar to Aedes atlanticus and Aedes tormentor Morphologically and ecologically with a wider white longitudinal stripe 2/3 down scutum with a wide stripe that continues on the head, the Legs and proboscis are unbanded and the Abdomen banding is less dorsal and more lateral triangles wiith white ventral and Subspiracular area with scales, Aedes infirmatus has a silvery patch on top of the silvery-white patch near the head of Aedes
Reduction/Elimination: This mosquito is difficult for homeowners to control through reduction and elimination. Mosquito Control monitors many swamps in the area that are known to be home for both of these mosquitoes, treating the area when it is wet and breeding is found.
On homes ATSB Attractant Toxic Sugar Baits have proven effective at control adult mosquito populations. Field studies demonstrated significant control of greater than 70% reduction for Aedes aedes infirmatus. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3944220/
