Phymatinae Laporte 1832
27 described spp. in 3 genera in our area(2), >280 spp. in 26 genera worldwide(1)
predatory bugs with dilated raptorial forelegs, clubbed antennae, and rear half of abdomen expanded (much wider than wings). Antennae are 4-segmented, beak 3-segmented, tarsi 3-segmented. Typically wait for prey on vegetation, especially flowers. In other subfamilies, antennae are not clubbed and forelegs usually not as dilated (if raptorial, modified otherwise).
