Identifying Grasshopper Species in Plumeria Gardens: A Visual Guide
Grasshoppers are common pests that can cause significant damage to plumeria plants by feeding on leaves, stems, and flowers. Different grasshopper species may be present in plumeria gardens, each with distinct characteristics and behaviors. This article provides an overview of common grasshopper species that may infest plumeria, offering detailed descriptions and photographs to help gardeners accurately identify and manage these pests.
Common Grasshopper Species in Plumeria Gardens
1. Differential Grasshopper (Melanoplus differentialis)
Description:
The differential grasshopper is a medium to large grasshopper species, typically measuring 1.5 to 2 inches (3.8 to 5 cm) in length. They are usually yellowish-brown to olive green with distinctive black chevron-shaped markings on the femur (upper leg segment) of their hind legs. They have a prominent, black, angled stripe on the top of their hind legs, which helps in identification.
Habitat and Behavior:
Differential grasshoppers are commonly found in gardens, fields, and agricultural areas. They are highly mobile and can move quickly between plants. These grasshoppers are known for their voracious appetite and can cause severe defoliation, especially during outbreaks.
Identification Tips:
- Look for the characteristic black chevron markings on the hind legs.
- Note the yellowish-brown to olive green coloration.
2. Red-Legged Grasshopper (Melanoplus femurrubrum)
Description:
The red-legged grasshopper is a smaller species, typically ranging from 0.75 to 1.25 inches (1.9 to 3.2 cm) in length. They have a brown to reddish-brown body with a distinct red tint on the hind legs. The hind legs also feature black bands and spines.
Habitat and Behavior:
Red-legged grasshoppers are found in grassy areas, gardens, and meadows. They feed on a wide variety of plants, including plumeria. While they generally prefer grasses, they can cause damage to ornamental plants during high population periods.
Identification Tips:
- Look for the reddish color on the hind legs and the smaller size compared to other species.
- Note the brown to reddish-brown body color and black banding on the legs.
3. Two-Striped Grasshopper (Melanoplus bivittatus)
Description:
The two-striped grasshopper is easily recognizable by the two pale yellow or white stripes that run from behind the eyes along the top of the thorax and down the wings. They are medium to large in size, typically measuring 1.5 to 2 inches (3.8 to 5 cm) in length. Their body color can vary from light brown to greenish-brown.
Habitat and Behavior:
This species is commonly found in gardens, fields, and open areas. They are generalist feeders and can consume a wide range of plant material, including plumeria. They are particularly damaging in large numbers and can strip plants of foliage.
Identification Tips:
- Identify the two distinctive pale stripes running from the head to the wing tips.
- Look for the light brown to greenish-brown body color.
4. American Grasshopper (Schistocerca americana)
Description:
The American grasshopper is one of the larger species, measuring 1.75 to 2.75 inches (4.4 to 7 cm) in length. They have a robust body with a brownish coloration and can sometimes have a yellowish tint. The hind wings are transparent with a yellowish tint, and the body may have black speckling.
Habitat and Behavior:
Found throughout the southern United States and Central America, the American grasshopper prefers open fields, gardens, and woodlands. They can be particularly destructive during outbreaks, feeding on a wide variety of plants, including plumeria.
Identification Tips:
- Note the large size and robust build.
- Look for the brownish coloration with possible yellowish tint and black speckling.
5. Gray Bird Grasshopper (Schistocerca nitens)
Description:
The gray bird grasshopper is a large species, typically ranging from 2 to 3 inches (5 to 7.5 cm) in length. They are generally gray to brown in color with a distinctive yellow stripe along the edge of the forewing. The hind legs have a reddish hue.

This species is commonly found in desert and arid regions but can also be seen in gardens and cultivated areas. They are strong fliers and can cover long distances. They feed on a variety of plants and can cause significant damage to ornamental plants like plumeria.
Identification Tips:
- Look for the large size and gray to brown coloration.
- Identify the yellow stripe along the forewing and the reddish hind legs.
Visual Identification
Photographs and Illustrations:
Include high-quality photographs and illustrations of each grasshopper species mentioned above. Focus on key identifying features such as coloration, markings, and size. Close-up images of the head, body, and legs can be particularly helpful.
Conclusion
Accurate identification of grasshopper species in plumeria gardens is essential for effective pest management. By recognizing the distinct characteristics of common grasshopper species, gardeners can implement targeted control measures to protect their plumeria plants from damage. Regular monitoring and early detection are key strategies in managing grasshopper infestations and maintaining healthy, vibrant gardens.
