NOVICE: Grasshopper

The differential grasshopper is an insect commonly found in Kentucky. This is a large, dark brown to olive green grasshopper, with adults averaging 1 1/2 to 1 3/4 inches in length. The underside of its body is yellow and it has clear shiny wings. Its primary distinguishing characteristic is the chevron-like black stripes on the femur of the hind leg.

Grasshoppers undergo gradual metamorphosis having only three life stages: the egg, nymph and adult. The nymphs differ from the adults in size and in the nature of the wings. The nymphs have nonfunctional wingpads whereas the adults have two pair of functional wings.

EXPERT: Common Stalk Borer

The common stalk borer can cause damage in corn where they are often found chewing down inside the whorl. Plants can become stunted or misshapen and may die. Young larvae are cream colored and have a dark brown or purple band around the body. When the larvae matures it may lack the band, making it difficult to identify. The larvae are very active when handled. The adult moths are grayish brown with small white spots on the front edge and along the tips of the front wings. The hind wings are pale grayish brown. Their wingspan is only about one inch.
