Anagrapha falcifera is a butterfly found in North America( moth ) fromthe owl butterfly family (Noctuidae).
features
butterfly
The wingspan of the moth is 32 to 34 millimeters. Greyish-brown tints predominate on the upper forewing. In the middle is a characteristic silver-white sign, for example in the form of the letter gamma from the Greek alphabet. This extends in a thin arc line and extends over the wing to the inner edge near the wing root. The middle field between the cell and the inner edge is colored black-brown to maroon-brown. The upper side of the hind wing is gray-brown and darkened at the edge. There is a comb-like tuft of hair on the furry, hairy thorax . The abdomen is provided with further short tufts of hair, the proboscis is well developed.
Caterpillar
Adult caterpillars are grass-green to turquoise-green in color. They show thin, white, interrupted secondary lines, many small white dots, a yellow-white side stripe and a few short, light hairs.
distribution and habitat
Anagrapha falcifera occurs in North America, mainly in southern Canada and in the east, north and middle of the USA . Evidence is also available from Newfoundland , Labrador, and California . The habitats include open spaces, roadsides, meadows, pastures, gardens, farmland, and wetlands.
Way of life
The moths of Anagrapha falcifera form several generations a year, which sometimes overlap and mainly affect the months of July and September. They are active during the day and at night, suckle on flowers during the day and visit artificial light sources at night . They like to sit on withered leaves as camouflage and are therefore hardly visible to predators. The caterpillars feed on the leaves of various plants, and include: blueberries ( Vaccinium ), cabbage ( Brassica ), carrots ( Daucus ), clover ( Trifolium ), corn ( Zea mays ), lettuce plants and snowball ( Viburnum ).
Pest Control
From the caterpillars of Anagrapha falcifera one is baculovirus won that for biological control can be applied.
