The Eastern Lubber Grasshopper in Texas: A Growing Concern
The Eastern Lubber Grasshopper (Romalea microptera) is a large, distinctive grasshopper native to the southeastern United States, and it has firmly established itself in the Texas landscape. While grasshoppers are a common sight, the Lubber's imposing size and often vibrant coloration distinguish it from other species. Its presence in Texas, particularly in recent years, has become a growing concern for both home gardeners and agricultural producers.
Increasing Prevalence and Spread
Reports of Eastern Lubber Grasshopper sightings have increased across Texas, suggesting a potentially expanding population. This rise is concerning because, while individual grasshoppers may not cause extensive damage, large populations can defoliate plants and impact crop yields. Their tendency to congregate in large numbers exacerbates this issue. The changing climate, with warmer winters, may be contributing to their increased survival rates and range expansion.
Potential Impact on Gardens and Agriculture
The Eastern Lubber Grasshopper is a polyphagous feeder, meaning it consumes a wide variety of plants. This broad diet makes them a potential threat to numerous garden plants, ornamental shrubs, and agricultural crops. While they may not always kill a plant outright, their feeding can weaken it, making it more susceptible to disease and other pests. The aesthetic damage they cause to ornamental plants is also a significant concern for homeowners.

Identifying the Giant Grasshopper: A Detailed Look
Now that we understand the increasing presence and potential impact of the Eastern Lubber Grasshopper in Texas, accurately identifying this insect becomes crucial for effective monitoring and management. These grasshoppers, known for their substantial size and striking appearance, are quite different from other grasshopper species found in the region.
Distinguishing Features of the Eastern Lubber Grasshopper
The Eastern Lubber Grasshopper ( Romalea microptera) is easily recognizable due to its size, color variations, and distinctive markings. Adults can reach lengths of up to 3 inches, making them one of the largest grasshopper species in North America.
Size and Color
The size alone is a key identifying factor.
Coloration varies considerably throughout its life cycle and even among adults. Nymphs (immature grasshoppers) are typically black with one or more brightly colored stripes – often yellow, orange, or red.
As they mature, their color patterns become more diverse.
Adults can be yellow, brown, reddish, or mostly black, often with contrasting markings. It's important to note that color is not a definitive identifier on its own, as variations exist within the species.
Distinctive Markings
Beyond color, look for specific markings. Adults often have yellow or orange stripes or spots along their bodies. A key identifying feature is the presence of red and yellow coloration on the hind wings, though these are rarely used for flight.
They possess short, non-functional wings, meaning they primarily move by walking or hopping.

Telling it Apart from Other Texas Grasshoppers
Texas is home to many grasshopper species, but the Eastern Lubber Grasshopper's size and bold colors help distinguish it from most others. Many common grasshoppers are smaller, more slender, and typically have a more muted green or brown coloration that provides camouflage.
Unlike Lubbers, most Texas grasshoppers are strong fliers.
Look for the combination of large size, bright colors (especially in nymphs), and limited flight ability to confirm identification. When in doubt, consulting field guides or online resources with high-quality images can be invaluable.
Life Cycle: From Nymph to Giant
Understanding the life cycle of the Eastern Lubber Grasshopper is also crucial for identification and management.
These grasshoppers have a relatively simple life cycle involving three stages: egg, nymph, and adult.
-
Eggs: Lubber grasshoppers overwinter as eggs in pods buried in the soil.
-
Nymphs: Nymphs emerge in the spring and undergo several molts as they grow, each time increasing in size and changing in coloration. As mentioned, nymphs are often black with bright stripes.
-
Adults: Adults appear in the summer and can live for several months. The entire life cycle takes approximately 6-9 months to complete.

Habitat Preferences
Eastern Lubber Grasshoppers are found in a variety of habitats, including open woodlands, weedy fields, roadside ditches, and gardens. They are particularly common in areas with abundant vegetation, as they are polyphagous feeders.
They are frequently observed on broadleaf plants. Keep an eye out for them in areas with milkweed, vegetables (especially cruciferous plants like cabbage and mustard), ornamental plants, and citrus trees.
Ecological and Agricultural Impact in Texas
Having established the characteristics that define the Eastern Lubber Grasshopper, it's vital to consider the consequences of its increasing presence within Texas ecosystems and agricultural landscapes. The impact of this insect extends beyond mere nuisance, potentially disrupting natural balances and causing economic hardship for farmers and gardeners.
Ecological Ramifications
The Eastern Lubber Grasshopper, while native, can exert significant pressure on native plant communities when population numbers surge.
Their voracious appetites lead to defoliation, which can weaken or even kill vulnerable plant species.
This defoliation not only affects the plants directly consumed but can also alter habitat structure, potentially impacting other insect species that rely on those plants for food or shelter.
The grasshopper's size and consumption rates mean that they can quickly outcompete other, smaller herbivores for resources, potentially leading to a reduction in biodiversity within affected areas. The full extent of these competitive interactions is still being studied, but the potential for disruption is clear.
Agricultural and Horticultural Damage
The agricultural impact of the Eastern Lubber Grasshopper is perhaps the most immediate and noticeable consequence of its proliferation.
These grasshoppers are not particularly picky eaters and will consume a wide variety of crops, garden plants, and ornamental species.
This broad diet makes them a threat to diverse agricultural operations, from large-scale farms to backyard gardens.
Damage manifests as chewed leaves, stems, and even fruits, weakening plants, reducing yields, and diminishing aesthetic value.
Economic Considerations
Quantifying the economic losses associated with Lubber Grasshopper infestations can be challenging, but the potential for significant impact is undeniable.
Reduced crop yields translate directly into lost revenue for farmers.
Furthermore, the cost of implementing control measures, such as insecticide applications or manual removal, adds to the financial burden.
For homeowners and gardeners, the loss of ornamental plants and vegetable crops can be frustrating and costly.
While precise figures are difficult to obtain without comprehensive statewide surveys, anecdotal evidence and regional reports suggest that the economic impact can be substantial, particularly during years with favorable conditions for grasshopper reproduction and survival.
Reports to Texas A&M AgriLife Extension
Texas A&M AgriLife Extension plays a crucial role in monitoring pest activity and providing guidance to Texans facing agricultural challenges.
Reports of Eastern Lubber Grasshopper damage received by AgriLife Extension offices across the state offer valuable insights into the geographic distribution and severity of infestations.
For example, vegetable gardeners in coastal regions often report complete defoliation of their plants. In central Texas, ornamental plants such as oleanders and crinum lilies are often favorite food sources for these grasshoppers.
These reports, while anecdotal, highlight the widespread nature of the problem and the diverse range of plants affected. The data collected by AgriLife Extension is critical for developing effective management strategies and providing timely advice to those impacted by this pest. Continued monitoring and reporting are essential for understanding the long-term trends and mitigating the negative impacts of Eastern Lubber Grasshoppers in Texas.
Effective Management Strategies for Giant Grasshoppers
The economic impact of Eastern Lubber Grasshopper infestations can be significant. Preventing and managing these infestations is crucial to protecting Texas ecosystems and agricultural productivity. A multi-faceted approach, rooted in Integrated Pest Management (IPM) principles, offers the most sustainable and effective solution.
IPM emphasizes a combination of strategies, prioritizing non-chemical methods and using chemical interventions only when necessary and in a targeted manner. This approach minimizes environmental impact and promotes long-term control.
Cultural Control Methods: Prevention and Early Intervention
Cultural control methods form the foundation of a successful IPM strategy. These practices focus on creating an environment less favorable to grasshoppers and promoting plant health to withstand potential damage.
Handpicking: A Direct Approach
One of the simplest, yet most effective methods, especially for smaller infestations, is handpicking. This involves physically removing grasshoppers from plants and destroying them.
The best time to handpick is early in the morning when the grasshoppers are less active due to cooler temperatures. Wear gloves and consider dropping the grasshoppers into a bucket of soapy water to ensure they do not escape and re-infest.
Promoting Plant Health: The Best Defense
Healthy, vigorous plants are naturally more resilient to pest infestations, including grasshoppers. Ensure plants receive adequate water, sunlight, and nutrients based on their specific requirements.
Regularly inspect plants for signs of grasshopper damage and address any underlying health issues promptly. Healthy plants can better tolerate some level of defoliation and recover more quickly.
Encouraging Natural Predators: A Biological Ally
Several natural predators feed on grasshoppers, helping to keep populations in check. Birds, lizards, and certain insect species, such as robber flies, are all effective predators.
Creating a habitat that attracts and supports these predators can significantly reduce grasshopper numbers. This can be achieved by planting native vegetation, providing water sources, and avoiding the use of broad-spectrum insecticides that can harm beneficial insects.
Chemical Control: A Targeted Approach
While cultural control methods should be the primary focus, chemical control may be necessary in cases of severe infestation. However, it's crucial to use insecticides responsibly and strategically.
Appropriate Insecticide Use
When selecting an insecticide, choose a product specifically labeled for grasshopper control. Always read and follow the label instructions carefully, paying attention to application rates, safety precautions, and environmental considerations.
Spot treatments are generally more effective than broad-spectrum applications. Targeting the areas where grasshoppers are actively feeding minimizes the impact on beneficial insects and the surrounding environment. Nymphs are often more susceptible to insecticides than adults, so early detection and treatment can be particularly effective.
Safety and Environmental Impact
Insecticides can pose risks to human health, wildlife, and the environment. Take precautions to minimize exposure by wearing appropriate protective gear, such as gloves, long sleeves, and a mask.
Avoid spraying on windy days to prevent drift and potential contamination of non-target areas. Consider using insecticides with lower toxicity to beneficial insects and pollinators to minimize disruption to the ecosystem.
Seeking Expert Advice
Managing Eastern Lubber Grasshoppers can be challenging. Consulting with experts from Texas A&M AgriLife Extension or qualified pest control professionals is highly recommended.
They can provide tailored advice based on your specific situation, including identifying the best management strategies, selecting appropriate insecticides, and implementing a comprehensive IPM program.
