Lymantria dispar, also known as the gypsy moth, and in the United States, the spongy moth, is a species of moth in the family Erebidae native to Europe and Asia.

The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, Lymantria dispar is listed among the world's 100 worst invasive alien species.
The etymology of "gypsy moth" is not conclusively known; however, the term is known to have been in use (as 'Gipsey') as early as 1832. Moths of the subfamily Lymantriinae are commonly called tussock moths due to the tussock-like tufts of hair on the caterpillars.
The name Lymantria dispar is composed of two Latin-derived words. The generic name Lymantria means 'destroyer'. The species epithet dispar means 'to separate' in Latin; it refers to the sexual dimorphism observed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Spongy Moth sighting in Cologne on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 174th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a Spongy Moth in Cologne on a given day, against under 5% in September to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spongy Moth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
32nd of 39
Of the 39 cities where we can rate Spongy Moth sightings, Cologne ranks 32nd at under 5%. The best odds are in Toronto (Canada, about 20%), London (United Kingdom, about 20%) and Busan (South Korea, about 20%).
Same family: Erebidae
The closest relatives of the Spongy Moth that you can see in Cologne (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Cinnabar Moth (about 10%), Pale Tussock Moth (about 10%) and Ruby Tiger Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spongy Moth is recorded against all the insects logged in Cologne (6 verified sightings), 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.
