In summer, a life cycle can be completed in 5 to 7 weeks. Following generations feed on other plantings of the same crop or on other hosts. One female moth may lay up to 1,500 eggs. The dome-like eggs have a ribbed surface and are pearly white when laid, but change to brown as they develop. The young caterpillars are predominantly green but the colors vary through development. When mature, larvae may be up to 2 inches long and usually have striped patterns over a base color that ranges from light green to brown to black. Distinct hairs are visible when held up to the light. Larval development takes 2 to 3 weeks before pupation occurs in the soil. The reddish-brown pupa stays in the soil for 10 to 14 days when not overwintering. Adults have light fawn forewings with a kidney-shaped spot in the middle. Hindwings are grey to grey-brown. Both wings have a broad dark band on the outer third of the wing but the band on the hind wing has a pale patch in the middle of the dark band. When resting, the wings are held roof-like over the body.]]> Fri, 29 Mar 2024 11:58:46 -0400 Fri, 29 Mar 2024 11:58:46 -0400 http://Images.bugwood.org/ <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=0454075 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=0454075 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1262032 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1262032 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265092 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265092 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265094 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265094 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265095 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1265095 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1262033 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1262033 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1263036 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=1263036 <![CDATA[old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=5389264 old world bollworm, cotton bollworm Helicoverpa armigera]]> http://www.ipmimages.org/browse/detail.cfm?imgnum=5389264
