They are similar to the lygaeids but differ in having numerous veins in the membrane of the hemelytra. Leptoglossus corculus (Say) occurs commonly in iongleaf and slash pine seed orchards in north Florida. First and second instar nymphs feed on the needles and first year conelets; older nymphs and adults feed on the seeds. Adults are reddish-brown to black, have long legs, and average 18 mm. in length. A white zig- zag line crosses the wings, and the hind tibiae are flattened and leaflike. Infested cones usually show no external damage symp- toms (188). The related species, L. occidentalis Heidemann, a serious pest of Douglas-fir seed in California (-W) has been ob- served feeding on the needles and green cones of Austrian pine in Missouri. FAMILY RHOPALIDAE The boxetder bug, Leptocoris trivittatus (Say), often becomes a pest wherever boxelder is grown as a shade tree in the United States and Canada. In heavily infested areas, it will feed on ash and maple. Adults (fig. IS) are somewhat flattened, brownish-black.
