Silver-spotted Skipper: What Tree Owners Need to Know

If you manage trees or landscapes in the southern or eastern United States, the Silver-spotted Skipper is an insect worth keeping on your radar. Observations of this insect in the wild — documented through research-grade iNaturalist reports — have prompted plant health professionals to flag it as a moderate-severity threat across several states. Here's what you need to know to stay ahead of it.

What Is the Silver-spotted Skipper?

The Silver-spotted Skipper is an insect pest currently tracked as a moderate threat to tree and plant health. It has been documented through verified, research-grade field observations, indicating that populations are active and present in monitored regions. While moderate in severity, "moderate" should never be read as "harmless" — left unmanaged, insect pressures of this kind can compound over time, stressing trees and making them vulnerable to secondary problems like disease or structural decline.

How to Identify the Silver-spotted Skipper

Silver-spotted Skipper identification begins with careful observation of your trees and surrounding landscape. Because specific symptom data is still being compiled for this pest, vigilance is especially important. Here's a practical approach:

• Monitor regularly. Walk your property and inspect foliage, stems, and the base of trees on a consistent schedule, particularly during warmer months when insect activity peaks.
• Look for signs of insect activity. General indicators of insect feeding include chewed leaf margins, rolled or webbed leaves, frass (insect droppings), or unusual leaf drop.
• Document what you see. Photograph any suspicious insects or plant damage. Research-grade observations — like those that flagged this pest — are invaluable for tracking spread.
• Use our platform tools. Upload photos and notes directly to our diagnosis tool for a faster, more accurate assessment of what you're dealing with.

If you're uncertain whether what you're seeing is related to Silver-spotted Skipper activity, don't wait. Early identification is your best asset.

Where Is the Silver-spotted Skipper Spreading?

Current tracking data places active Silver-spotted Skipper observations in the following states:

• Oklahoma
• Texas
• Maryland
• North Carolina
• Connecticut

This distribution spans both southern and northeastern regions of the country, suggesting the insect can thrive across a range of climates. If you live in or near any of these states, your trees may be at risk. Landowners in adjacent states should also remain watchful, as insect populations rarely respect state borders.

Silver-spotted Skipper Treatment Options

If you've confirmed or strongly suspect Silver-spotted Skipper activity on your property, several Silver-spotted Skipper treatment strategies are available. A layered, integrated approach is generally most effective.

1. Targeted Insecticide Application Applying an appropriate insecticide can be highly effective when timed correctly. Timing is critical — treatments should align with the pest's vulnerable larval or adult emergence stage. Always read and follow the product label in full before application. Misapplication can harm beneficial insects, including pollinators, so precision matters.

2. Biological Control Agents Working with nature is one of the most sustainable long-term strategies. Encouraging or introducing natural predators and parasitoids — such as predatory beetles or parasitic wasps — can help suppress populations without heavy chemical inputs. For caterpillar-stage pests, Bt (Bacillus thuringiensis) is a well-established biological option that targets larvae while remaining safe for most other wildlife.

3. Infested Material Removal Pruning and destroying infested branches and plant material removes active pest populations and reduces the number of eggs or larvae that can overwinter and re-emerge. Be thorough: remove fallen debris from around the base of trees as well. Critically, dispose of all infested material away from healthy trees to avoid inadvertently spreading the problem.

When to Call a Certified Arborist

Some situations call for professional eyes. You should contact a qualified arborist if:

• You're unsure whether the insect or damage you're seeing is Silver-spotted Skipper-related
• Damage appears to be worsening despite your own treatment efforts
• Multiple trees on your property are showing signs of stress simultaneously
• You're considering insecticide application but want guidance on product selection and timing
• Your trees are mature, high-value, or located near sensitive ecosystems

A certified arborist can assess your specific situation, confirm identification, and build a targeted management plan. Use our find an arborist tool to locate a qualified professional in your area.
