Walnut Twig Beetle
Bristly foxtail isn't all bad! Here it has captured and killed some masked chafer beetles in its sticky awns. It commonly captures beetles and other insects. Bristly foxtail is an exceptionally obnoxious annual weed. Its insect killing ways are no reason to save this plant. Do the environment a favor, get rid of this weed whenever possible.
