BIONOMICS. — The females are fierce biters, attacking principally in the 

 open, but also freely entering houses. Adults frequently migrate considerable 

 distances from their breeding places. Larvae occur in coastal marshes, including 

 both fresh and salt water, but less brackish water seems to be preferred.
