Phanaeus vindex, also known as a rainbow scarab (like other members in its genus), is a North American species of true dung beetle in the family Scarabaeidae.

It is the most widespread species of Phanaeus in the United States and it has a wide habitat tolerance. It may hybridize with the generally less common P. difformis.
P. vindex adults are hard-bodied beetles which range from approximately 11-22 millimeters (0.4-0.9 inches) in length. They are relatively bulky and oblong. These beetles are sexually dimorphic; the males can be identified by their iridescent elytra and a large horn on their heads while females have slightly less vibrant shells and lack horns. Females also have different numbers of segments on their abdomen than males. Additionally, the ends of male abdomens raise above the elytra, however, in females, they do not. On top of this, the abdomen is distinctly colored in both sexes. Like most Phanaeus species, male rainbow scarabs can be observed in either a major morph with large horns and bodies, or a minor morph, with significantly... Wikipedia →

Rare
Under 5% of wildlife watchers report a Rainbow Scarab sighting in Dallas on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1213th most-seen of the 1412 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rainbow Scarab in Dallas on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Rainbow Scarab sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Rainbow Scarab sightings, Dallas ranks 3rd at under 5%. The best odds are in Miami (United States, about 10%) and Orlando (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the Rainbow Scarab is recorded against all the insects logged in Dallas (6 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.
