As warm and wet as it has been, the summer's most abundant harvest has probably been the plethora of mosquitoes we're experiencing, particularly when day starts giving way to night and the air is moist and still. Try as I might, I've yet to find a truly reliable repellent, but that hasn't really stopped me from venturing forth morning, noon, and, as happened here, night. Armed with a small but powerful camera light, I combed the goldenrod patch in the hope that I'd find some photogenic caterpillars or beetles, but they were elsewhere. What I did find, however, was a small and drab mosquito, and as I zoomed close, I noticed something pretty special. Only the females bite, of course, and this is certainly one way to tell the sexes apart. This guy—and he was clearly a "he"—showed another way to separate the men from the women: check the antennae. Females have simple and modest detectors. Males are endowed with large frills, all the better to comb the air while dining on pollen, detect her pheromonal perfume, and zero in to, if she's willing, mate.
