Weeping Willow with Wingless Yellowjacket-Like Insects: Likely Lady Beetles

A 20-foot weeping willow in South Carolina has few leaves, green stems, and many wingless yellowjacket-like bugs. Other trees nearby are healthy.

Identification

The insects are likely lady beetle (ladybug) larvae or adults—beneficial predators. They don't harm the tree but may be feeding on aphids or other pests.

Next Steps

• Confirm with a photo if possible.
• Check for aphids or scale on leaves/stems.
• If lady beetles, no treatment needed—they're helping.

Tree thinning may be due to other stress (root issues, water, soil). A photo would allow better diagnosis.
