Migratory Locust - South Sudan

Locust plagues have been a threat to the agricultural stability of Africa. Large and recurring infestations are devastating. Locust eat enormous quantities of vegetation as larvae. As adults, they are capable of eating the equivalent of their body weight each day. They are strong flyers, highly mobile, and difficult to contain.

Locusta migratoria - The migratory locust is the most common of the locust species and can be found throughout Africa and Asia. It is a polyphenic insect, a term describing an animal whose pigmentation and size varies in accordance to its gregarious or solitary phase and age. In high density populations, the migratory locust is small, yellow to orange in color, and has a black spotted pigmentation. In its solitary form, they are much larger and appear brown or green to match the surrounding vegetation.

Field Cricket - Curaçao

Aruba, Bonaire, Curaçao, and the country of Trinidad and Tobago are located on the South American continental shelf. In geological terms, this makes these islands part of South America and not the Caribbean. The three Dutch holdings lie in the western section of the Lessor Antilles and are rarely subjected to hurricanes.

Gryllus bryanti - Young field crickets, nymphs, shed their exoskeleton several times before emerging as adults. Crickets and grasshoppers are often misidentified. Crickets have long antennae and rub their wings together to produce their chirping sound; grasshoppers have short antennae and produce their singing by rubbing their legs against the wings. Gryluss btyanti is a large field cricket, dark brown in color, with a reddish tint along the head area. Unlike other crickets, when chirping, this species produces only one pulse per stroke.
