Callosamia angulifera, the tuliptree silkmoth or giant silkmoth, is a moth of the family Saturniidae. It is found in North America from Massachusetts east through central New York, southern Ontario, and southern Michigan to central Illinois, south to the Florida panhandle and Mississippi.
The wingspan is 8–11 cm (3.1–4.3 in). In the north there is one generation per year, with adults on wing from June to August, while in the south there are two generations per year, with adults on wing from March to April and again in August.

Rare
Under 5% of wildlife watchers report a Tulip-Tree Silkmoth sighting in Baltimore on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 308th most-seen of the 705 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 July
In those months about 10% of wildlife watchers report a Tulip-Tree Silkmoth in Baltimore on a given day, against under 5% in August to April, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Tulip-Tree Silkmoth sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 3 cities where we can rate Tulip-Tree Silkmoth sightings, Baltimore has the highest daily chance: under 5%. Next come Washington (United States, under 5%) and Philadelphia (United States, under 5%).

GBIF citizen-science records
It is estimated from how often the Tulip-Tree Silkmoth is recorded against all the insects logged in Baltimore (15 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.
