Spongy Moth
Lymantria disparAlso known as Gypsy Moth, European Gypsy Moth, Asian Gypsy Moth
Spongy moths are notorious forest defoliators whose populations undergo dramatic boom-and-bust cycles, occasionally stripping entire hillsides of their leaves in midsummer. While the flightless females are creamy white and heavily patterned, the smaller, brownish males fly actively during the day in search of mates. The species gets its common name from the tan, felt-like egg masses that females plaster onto tree bark, rocks, and outdoor equipment.

Avoid touching caterpillars or egg masses with bare hands, and wear protective gear when scraping eggs.- Egg Mass Removal: Scrape the spongy, tan egg masses into soapy water during winter to protect local trees.
- Burlap Banding: Wrap tree trunks in burlap to trap caterpillars as they climb down to hide during the day.
- Reporting Sightings: Document and report new infestations to local agricultural extension offices to help track spread.
