Hylesia nigricans is a species of Lepidoptera of the family Saturniidae. It is a nocturnal moth endemic to Argentina and Brazil. It can be found mainly in the north and center of Argentina, the south of Bolivia and the south of Brazil, due to climatic factors which favor its reproduction. The species was first described by Carlos Berg in 1875.
The female adult can reach an average wingspan of 45 mm. Its larvae have an average length of 40 to 45 mm, with black and yellow bodies covered by urticating hairs which, upon contact with skin, produce irritation, causing an extended dermatitis.

It possesses a voracious appetite, attacking fruit bearing, ornamental and forest plants. It was declared a national plague in Argentina in 1911. There exists a range of chemical products aimed at controlling their development.
The eggs are laid in overlapping layers of up to 900, protected by a yellow cocoon built by the female using her secretions and abdominal... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Hylesia nigricans is recorded against all the insects logged in Montevideo (9 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.
