I don't remember seeing one of these before. A mosquito? I found it resting on an 'Eyelash' salvia leaf. I ran inside the house for my camera so I could snag some shots. She (?) rested there for quite a long time. At my desk, I snooped around on Bugguide.net and found her. This is an elephant mosquito (Toxorhynchites rutilus).
According to the online species account, "Adults take nectar. Larvae feed on aquatic insects, especially other species of mosquites, becoming cannibalistic sometimes. Adults are day-fliers. Overwinter as late-instar larvae or as adult (southern part of range?). Has been reared for biological control. Predatory mosquitoes in the genus Toxorhynchites are the most common arthropods which have been used for control of "container-breeding" mosquitoes. The combination of carnivorous larvae and innocuous adults is very attractive in biological control. Successful biological control has been reported using Toxorhynchites species from Japan, Southeast Asia, the Caribbean and the United States."
