Ligyrus gibbosus, the carrot beetle, is a species of rhinoceros beetle in the family Scarabaeidae. Adults are 13–17 mm (0.5–0.7 in) long, dark reddish-brown to black, and larvae are white with a dark head. It feeds on roots, grasses, and decaying vegetation in the soil, and is a pest of sunflowers and other crops.
L. gibbosus was formerly placed under the genus Tomarus until a 2022 revision by López-García, M.M. and C. Deloya. Wikipedia →

Rare
Under 5% of wildlife watchers report a Carrot Beetle sighting in Saguaro National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 300th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July–August and November
In those months about 10% of wildlife watchers report a Carrot Beetle in Saguaro National Park on a given day, against under 5% in September–October and December–June, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Carrot Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
2nd of 2
Of the 2 parks where we can rate Carrot Beetle sightings, Saguaro National Park ranks 2nd at under 5%. The best odds are in Death Valley National Park (United States, about 10%).
Same family: Scarabaeidae
The closest relatives of the Carrot Beetle that you can see in Saguaro National Park (family Scarabaeidae, Scarabs) are Figeater Beetle (about 10%) and Lesser Triceratops Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Carrot Beetle is recorded against all the insects logged in Saguaro National Park (5 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.
