Aedes infirmatus and Aedes tormentor are very similar in where they are found and in appearance. They are both very persistent biters and have been found to seek blood meals during the middle of the day. They are not known to be able to transmit disease to humans or animals.

Description: Both of these mosquitoes are medium sized, dark-brown mosquitoes. The difference is the marking on the back. Aedes infirmatus has a broad silvery patch, whereas Aedes tormentor has a long, silvery line.

Home: These mosquitoes breed in temporary rain pools found in wooded areas and open fields. The larvae develop very quickly to the adult stage.

Feeding: Neither mosquito is picky about what it feeds on, obtaining blood meals from all forms of animal life, including humans, that move through the cool, shaded woodland areas where they breed.

Reduction/Elimination: This mosquito is difficult for homeowners to control through reduction and elimination. Mosquito Control monitors many swamps in the Jacksonville area that are known to be home for both of these mosquitoes, treating the area when it is wet and breeding is found.
