Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths. It was first described by Johan Christian Fabricius in 1793. The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.
As the common name of the species implies, the preferred host trees are maple trees. Adult females lay their yellow ovular eggs in groups of 10 to 40 on the underside of maple leaves. The emerging caterpillars, also known as the greenstriped mapleworm, mainly feed on the leaves of their host maple trees, particularly red maple, silver maple, and sugar maple. Since the caterpillars eat the entire leaf blade, in dense populations, caterpillars have been known to defoliate trees, resulting in aesthetic rather than permanent damage. However, like all other Saturniid moths, the adult moths do not eat.
The rosy maple moth is the smallest of the silk moths; males have a wingspan of 3.2 to 4.4 centimeters (1.25-1.75 in); females of 3.8 to 5 centimeters... Wikipedia →

Possible
About 20% of wildlife watchers report a Rosy Maple Moth sighting in Shenandoah National Park on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 51st most-seen of the 723 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June to August
In those months about 20% of wildlife watchers report a Rosy Maple Moth in Shenandoah National Park on a given day, against under 5% in October to March, the lowest months.

GBIF citizen-science records
It is estimated from how often the Rosy Maple Moth is recorded against all the insects logged in Shenandoah National Park (66 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
