Anisota senatoria, the orangestriped oakworm, also known as the orange-tipped oakworm, is a Nearctic moth of the family Saturniidae and subfamily Ceratocampinae. It is one of the more common Saturniids, reaching pest status occasionally in the northern parts of its range. As they are late-season feeders, however, they do little lasting damage to their hosts (most of the has been stored already). It is very similar to A. finlaysoni in southern Ontario and A. peigleri in the southern US. The species was first described by James Edward Smith in 1797.
The species lives in eastern North America, from the edge of the Great Plains to the east coast and from southern Ontario to central Georgia, Alabama and eastern Texas. They are found in northern Florida, but are more common in the north.
There is only one brood a year. Eggs are laid on the underside of leaves in large clusters. They take one to two weeks to hatch. Larvae are gregarious in the early instars and often do not disperse much in the late instars. The fifth instar is black with yellow-orange stripes on its side, and prominent spiny horns on the second segment of the thorax, about... Wikipedia →

Rare
Under 5% of wildlife watchers report an Orange-Tipped Oakworm Moth sighting in New York City on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1165th most-seen of the 1623 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Orange-Tipped Oakworm Moth in New York City on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Orange-Tipped Oakworm Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Orange-Tipped Oakworm Moth sightings, New York City ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Orange-Tipped Oakworm Moth is recorded against all the insects logged in New York City (8 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.
