Chrysina woodi
In 3 days ~40% in a week ~70%
Chrysina woodi, or Wood's jewel scarab, is a species of shining leaf chafer in the family of beetles known as Scarabaeidae. This bright green beetle is native to Chihuahua in Mexico, and New Mexico and Texas in the United States. This beetle is 25–35 mm (1.0–1.4 in) long and it resembles C. beyeri, but that species has all blue-purple legs and tarsi (in C. woodi, the legs are green and the tarsi blue).
The name was first published in the minutes of a meeting in 1884 as woodi, in advance of the formal description of the species as woodii in 1885, but under ICZN Article 50.2, the 1884 name and spelling take precedence. Adults of this species have been documented feeding mostly on Texas black walnut (Juglans microcarpa), but they have also been reported to feed on a small number of additional plants. Wikipedia →

Possible
About 20% of wildlife watchers report a Wood's Jewel Scarab sighting in Guadalupe Mountains National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 57 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.
September and October
In those months about 40% of wildlife watchers report a Wood's Jewel Scarab in Guadalupe Mountains National Park on a given day, against under 5% in November to August, the lowest months. Those are among Guadalupe Mountains National Park's wettest months, with about 35 mm of rain a month against 10 mm in April.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Wood's Jewel Scarab sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Guadalupe Mountains National Park, in our data
Guadalupe Mountains National Park is the only park on Wallace's Line with enough records to rate Wood's Jewel Scarab sightings: about 20% of wildlife watchers there report one on a given day.

The closest relatives of the Wood's Jewel Scarab that you can see in Guadalupe Mountains National Park (order Coleoptera, Beetles) are Obscure Darkling Beetle (about 30%), Stenomorpha opaca (about 20%) and Lampetis drummondi (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wood's Jewel Scarab is recorded against all the insects logged in Guadalupe Mountains National Park (11 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.
