Pest LocationRow Crop
Adults are vary in color from yellowish to pale brownish and are covered with small black specks. There is also a short black line on the wing tips which extends beyond the abdomen. A conspicuous spine on the middle of the front tibia may also be noticed. They are about 1/2-inch long. Eggs are metallic bronze.
This species may be confused with Euchistus species, which are common plant feeding stink bugs. The spined soldier bug has more acute spines on the edge of the pronotum.
Prey include many kinds of caterpillars and grubs, especially those with few hairs. They are known to prey on larvae of the fall armyworm and the Colorado potato beetle.
Eggs are laid in small clusters of 20-30 on leaves of plants. Immatures may be found clustered around the eggs shortly after they hatch. Young nymphs may feed on plant juices but later stages are predaceous. Each female may lay up to 1000 eggs. Adults may live for 5 to 8 weeks.
