Corn Earworm (Helicoverpa zea)

Corn Earworm (Helicoverpa zea)

Helicoverpa zea, commonly known as the corn earworm, is a species (formerly in the genus Heliothis) in the family Noctuidae. The larva of the moth Helicoverpa zea is a major agricultural pest. Since it is polyphagous (feeds on many different plants) during the larval stage, the species has been given many different common names, including the cotton bollworm and the tomato fruitworm. It also consumes a wide variety of other crops.

The species is widely distributed across the Americas with the exception of northern Canada and Alaska. It has become resistant to many pesticides, but can be controlled with integrated pest management techniques including deep ploughing, trap crops, chemical control using mineral oil, and biological controls.

The species migrates seasonally, at night, and can be carried downwind up to 400 km. Pupae can make use of diapause to wait out adverse environmental conditions, especially at high latitudes and in drought.

FW is yellowish tan to dull orange with a darker band beyond toothed PM line. Reniform spot typically has dusky dot in inner half. HW is whitish with blackish veins and wide terminal line.

Hosts: Low plants and crops, including corn, cotton, tomato and tobacco.

The Yellow-Spotted Renia (Renia flavipunctalis)

The Yellow-Sotted Renia (Renia flavipunctalis) is a litter moth of the family Erebidae. It is found from southern Canada (from Nova Scotia west to Alberta) to Florida and Texas.

The wingspan is 26–31 mm. Adults are on wing from June to August. There is one generation in the north-east.

Violet gray FW has PM line that curves smoothly inward before reaching costa. Reniform spot is yellow or black. Indistinct ST line is bordered with a band of brown shading. Male has a tuft beyond midpoint of antennae.

Hosts: The larvae feed on organic matter, including dead leaves of deciduous trees.

Lunate Zale (Zale lunata)

The Lunate Zale is a species of moth of the family Noctuidae. It is found in the East of North America. The wingspan is 40–55 mm. The moth flies from March to September depending on the location.

Adults – quite variable with both fore- and hindwings dark brown with shades of yellow, red brown and black, sometimes with white or silver marginal patches.

Idaea bonifata

Idaea bonifata

Idaea bonifata is a moth in the family Geometridae. It is found in North America, where it has been recorded from Arizona, California, Georgia, Illinois, Kentucky, Maryland, Nevada, New Mexico, Oklahoma, Pennsylvania, Tennessee and Utah. The length of the forewings is 6–7 mm. Adults are on wing from March to October.

Idaea bonifata is VERY tiny and often overlooked, so I’m not surprised the range on MPG doesn’t have it there. Then again, the ranges on MPG are incomplete for many species, and over-representative for others.

Photographed in Connecticut; 10/5/18

Hosts: The larvae feed on decaying leaves and stored grains.

Wavy-Lined Emerald (Synchlora aerate)

Wavy-Lined Emerald (Synchlora aerate)

Synchlora aerata, the Wavy-Lined Emerald moth, is a species of moth of the Geometridae family. It is found in most of North America.

Pale green wings have slightly wavy white AM and PM lines. Dotted whitish ST line is sometimes noticeable. Fringe on all wings is tinged pale green. Abdomen has narrow white dorsal stripe running entire length.

Hosts: The larvae feed on a wide variety of plants, including the flower heads of composite flowers and other flowering plants, as well as shrubs and trees. Recorded food plants include Aster, Rudbeckia, Liatris, Solidago, Artemisia, Achillea and Rubus species. They attach bits of the plant tissue on which they are feeding along their backs. The species overwinters as a partially grown larva.
