Caulotops barberi, small bugs measuring about 0.6 inches (1.6mm) long, which attack Agaves and other succulents. Large populations may be found on given plants, with damaging numbers developing late summer or early fall. Bugs feed on leaves and cause a light yellow-tan scar at the point of feeding. If left untreated, plants will decline and eventually die. We see huge populations of Agaves across Arizona just decimated by running bugs. Damage is extremely unsightly.
Caulotops barberi may be controlled by using insecticidal soap or a broad spectrum ornamental plant insecticide. Chemicals should be applied in early morning or late evening when the bugs are most active. Several applications of the insecticidal material may be needed, and complete control may be beyond reach. I know of one prominent Tucson nursery so frustrated by running bugs, it is seriously considering dropping Agaves from its horticultural offerings.
