This insect is particularly fond of plants in the family Cruciferaceae, which includes mustards, pepper grass, bittercress, and others, as well as many important crops such as corn, beans, tomatoes, squash. As they feed they cause discoloration and wilting of the plant tissues, and young plants may be killed. Typical of many true bugs the adult stage over-winters, usually concealed in plant debris, and often active in the winter in warmer Gulf Coast areas. They resume activity in the spring when the female lays up to 155 eggs, in double rows of about a dozen eggs which hatch in about 3 weeks, and sooner in warmer months for later generations. Development through 5 instar stages to the adult insect takes about 7 weeks, with up to 4 generations per year.
Good cleanup of fallen leaves and other plant debris in the fall will reduce over-wintering sites and remove many of the bugs that have hidden there. Small numbers of the insects on landscape plants may be tolerated and little to no damage would be noticed. For larger infestations a residual contact insecticide applied to the foliage may be effective. Since they also feed on weeds the removal of weed growth, particularly legumes, along the perimeter of crops or landscape will help reduce the numbers of the bugs in the area.
