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.
