Heliothis is a genus of moths in the family Noctuidae. It was first described by Ferdinand Ochsenheimer in 1816. Some of the species have larvae which are agricultural pests on crop species such as tobacco, cotton, soybean and pigeon pea. Some species originally in this genus have been moved to other genera, see Chloridea and Helicoverpa.
The proboscis is fully developed. Palpi porrect (extending forward) and second joint evenly clothed with long hair. The third joint is short and depressed and a short frontal shift. Thorax and abdomen without tufts. Fore tibia has a pair of slender terminal spines, whereas mid and hind tibia also spined. Forewings with veins 8 and 9 sometimes given off from the end of the areole.
