Common Name(s): Big-Eyed Bug
Several species are found in Texas, with Geocoris punctipes (Say), a large gray species, and G. uliginosus (Say), a small black species, being common in cotton fields. Species range is size from 1/8 to 1/4 inch long and have broad heads with large, curbed, backward-projecting eyes. Immature stages (nymphs) resemble adults but do not have fully developed wings.
Nymphs and adults are general predators, feeding on small caterpillars and caterpillar eggs, fleahoppers, lygus bugs, mites, thrips, whiteflies. They will also feed on various seeds and suck plant juices but are not considered to be injurious to plants. They occur in most crops and landscapes.
Adults overwinter and lay eggs on plants. Nymphs hatching from eggs develop through 5 stages before becoming winged adults.
