"7.5 mm (not counting appendages) According to BugGuide, this sp. is ""found in vegetation near streams and marshes, about a meter above the ground"". I noticed them in the wildflower (mostly milkweed) patch in my yard within days of Hurricane Irene. With the Raritan close to 30' above flood stage, I speculated that they were flushed from their former home, ending up in my backyard a few hundred meters away. But here it is 4 yr later. Either they are not so picky about habitat to begin with & were here all along, or they did indeed show up here after flooding but found conditions congenial & have successfully colonized the place. There were males singing, as well as this female. Members of this family are omnivores. If they can eat the Oleander Aphids (Aphis nerii) on the milkweed, they've got it made. If not, there's plenty of Uroleucon aphids on the Oxeye Sunflower."
