Nysius raphanus

Nysius raphanus is a small North American insect in the order Hemiptera and family Lygaeidae. They are grey to brown in color, with largely transparent wings, and can release an offensive odor similar to stinkbugs. They have no larval stage, instead going through several nymph stages with the nymphs resembling adults but having no wings. In high numbers false chinch bugs can cause significant plant damage.
