The green cloverworm (Hypena Scabra) is a moth of the phylum Arthropoda, order Lepidoptera, and subfamily Noctuoidea. They are also known as black snout moths and are responsible for soybean defoliation which is tough to control.
The larvae are pale yellow to light green in color and have a white stripe running on each side of their bodies.
Adult identification is quite easy. They have four pairs of prolegs in an arrangement that one pair is at the end of the body and the rest three pairs in the middle of the body and an extension of white stripes on both sides.
The green cloverworm is a leaf-feeding insect that can mostly be found in soybean fields from late June to September and has a life cycle of two generations every year.
The countries of the United States and Canada are where you can easily spot these moths. Although they are behind soybean defoliation, they are not considered serious pests in the southern states.

The green cloverworm life cycle has two stages. The first stage if when larvae become a caterpillar, and the second is when the caterpillar becomes a moth. The total time larvae take to become a caterpillar is roughly around 14-26 days and time taken for a caterpillar to become a moth is around 20-30 days.
How do they reproduce?
Soybean green cloverworm moths prefer the warm temperatures of spring to mate. Females lay eggs on the underside of the plant and the eggs take four to five days to hatch.
The young larvae almost take a month to develop completely as they develop in six stages. Older larvae are buried into the soil to pupate for an approximate duration of 7-10 days.
