Leafhoppers are small, agile insects known for their jumping abilities and plant-feeding habits. This list covers 25 distinct types of leafhoppers, highlighting their unique physical traits, habitats, and behaviors. Whether you’re an entomologist, gardener, or nature enthusiast, this guide will help you identify these fascinating insects with clarity and confidence.
1. Glassy-winged Sharpshooter (Homalodisca vitripennis)
The glassy-winged sharpshooter is a large leafhopper species recognized by its translucent wings and striking yellow body with black markings. Native to the southeastern United States, it is notorious for spreading the bacterium that causes Pierce’s disease in grapevines, making it a significant agricultural pest.
2. Potato Leafhopper (Empoasca fabae)
Commonly found across North America, the potato leafhopper is small and pale green with a wedge-shaped body. It damages crops like potatoes, beans, and alfalfa by feeding on sap, causing leaf yellowing and curling known as “hopperburn.”
3. White Apple Leafhopper (Typhlocyba pomaria)
This species is predominantly found in apple orchards in North America. It is creamy white with subtle greenish hues and feeds on apple leaves, leading to reduced photosynthesis and fruit quality.
4. Green Sharpshooter (Oncometopia alpha)
Green sharpshooters display a bright green coloration with distinctive wing venation. They inhabit southern U.S. states and Mexico, feeding on a variety of plants and occasionally transmitting plant pathogens.
5. Graphocephala coccinea (Candy-striped Leafhopper)
Known for its vivid red and blue striped wings, the candy-striped leafhopper is visually striking. It is found in eastern North America and feeds on a wide range of herbaceous plants without causing major economic damage.
6. Scaphoideus titanus
Native to Europe, Scaphoideus titanus is a significant vector of Flavescence dorée, a serious grapevine disease. It has a yellow-green body with darker markings and is closely monitored in viticulture regions.
7. Graphocephala fennahi (Rhododendron Leafhopper)
Introduced to Europe from North America, this leafhopper is recognized by its colorful blue and red wings. It feeds exclusively on rhododendrons and can cause leaf damage in ornamental gardens.
8. Cicadulina mbila (Maize Leafhopper)
This small yellow leafhopper is a major pest in African maize crops, primarily because it transmits the maize streak virus. Its presence can lead to severe yield losses in affected regions.
9. Agallia constricta
Found in North and Central America, Agallia constricta is a bright green leafhopper with a distinctive constricted thorax. It feeds on grasses and is often spotted in meadows and pastures.
10. Erythroneura elegantula (Western Grape Leafhopper)
This species is a common pest in California vineyards, identified by its white and yellow patterned wings. It feeds on grapevine leaves, causing stippling and reduced photosynthetic efficiency.
11. Exitianus exitiosus (Brown Leafhopper)
Widespread in North America, the brown leafhopper has a mottled brown coloration that provides excellent camouflage. It feeds on a variety of grasses and herbaceous plants but rarely causes significant damage.
12. Empoasca vitis (Vine Leafhopper)
Found primarily in Europe, this leafhopper is yellow-green with a slender body. It is a pest of grapevines, and its feeding can lead to leaf discoloration and defoliation if populations are high.
13. Oncometopia orbona (Broad-headed Sharpshooter)
Recognizable by its broad head and greenish body with black markings, this sharpshooter is common in the southern United States. It feeds on a wide range of plants and can transmit diseases to fruit trees.
14. Cicadella viridis (Green Leafhopper)
One of the most common leafhoppers in Europe, the green leafhopper is bright green with red eyes. It inhabits grasslands and gardens, feeding on grasses and herbaceous plants.
15. Empoasca decipiens
Known as a pest in greenhouse crops, Empoasca decipiens is pale yellow with transparent wings. It damages a variety of vegetable plants by piercing and sucking sap, causing leaf curling and discoloration.
16. Graphocephala atropunctata (Blue-green Sharpshooter)
This species is notable for its metallic blue-green body with yellow markings. It is a vector of the bacterium causing Pierce’s disease, posing a threat to vineyards in California.
17. Exitianus capicola
Native to parts of Africa, this leafhopper is brown with subtle patterning and prefers grassland habitats. It plays a role in local ecosystems but is not considered a major pest.
18. Nephotettix virescens (Green Rice Leafhopper)
This leafhopper is a key pest in rice cultivation across Asia, recognized by its bright green color. It transmits rice tungro virus, leading to significant crop losses if unmanaged.
19. Empoasca kraemeri
Found in Central and South America, this species is small and yellow-green with delicate wings. It feeds on various crops, occasionally causing minor damage in agricultural settings.
20. Cicadulina bipunctella
Another maize pest in Africa, this leafhopper is yellow with two distinct black spots on its wings. Like Cicadulina mbila, it can vector maize streak virus, affecting crop health.
21. Erythroneura ziczac
Common in North American vineyards, this leafhopper has striking zigzag wing patterns in yellow and brown. It feeds on grapevines and can reduce photosynthetic capacity when abundant.
22. Balclutha incisa
Widespread in Europe, this species is small with a mottled brown appearance. It is often found on grasses and is mostly harmless to cultivated plants.
23. Cicadella sexnotata
Recognized by six distinct spots on its wings, this leafhopper inhabits wetlands and marshy areas in North America. It feeds on sedges and grasses, contributing to wetland ecosystem dynamics.
24. Empoasca abrupta
This species is pale green with a slightly pointed head, found across parts of Europe and Asia. It feeds on various herbaceous plants and can cause minor leaf damage in gardens.
25. Graphocephala versuta (Versute Leafhopper)
Known for its bright red and green coloration with intricate wing patterns, the versute leafhopper is native to North America. It primarily feeds on deciduous trees and shrubs without causing significant harm.
How to Choose
When identifying or choosing leafhoppers to study or monitor, focus on key characteristics such as body coloration, wing patterns, size, and habitat preferences. Geographic location is crucial since many species have limited ranges. Additionally, understanding the host plants they feed on can help narrow down identification, especially for agricultural or horticultural purposes. Photos should be examined for distinctive markings like wing venation, spots, or color bands. Finally, consider the species’ ecological or economic impact, as some leafhoppers are vectors of plant diseases and require closer attention.
Frequently Asked Questions
Q: What is the main difference between leafhoppers and sharpshooters?
Sharpshooters are a subgroup of leafhoppers that tend to be larger and have broader heads, with some species acting as vectors for serious plant diseases.
Q: Are leafhoppers harmful to all plants?
Not all leafhoppers cause significant damage, but many feed on plant sap, which can weaken plants or transmit diseases, especially in crops like grapes, rice, and maize.
Q: How can I prevent leafhopper damage in my garden?
Maintaining plant health, encouraging natural predators like ladybugs, and using insecticidal soaps or neem oil can help reduce leafhopper populations.
Q: Can leafhoppers jump or fly?
Leafhoppers are excellent jumpers and also have wings that allow them to fly short distances, aiding in their rapid dispersal.
Q: Are leafhoppers attracted to specific plants?
Yes, many species have particular host plants they prefer, which can aid in identification and management strategies.
Final Thoughts
Leafhoppers are a diverse and ecologically important group of insects with many species exhibiting unique colors, patterns, and behaviors. Proper identification is essential for managing their impact on agriculture and understanding their role in ecosystems. By focusing on physical traits, habitat, and host plants, enthusiasts and professionals alike can better appreciate these small yet significant insects.
