Cycloneda sanguinea, also known as the spotless lady beetle, is a widespread species of ladybird beetle in the Americas. Cycloneda sanguinea is the most widespread ladybird beetle in Latin America, typically found in plant-dense landscapes ranging from the southern United States to Argentina, and eastward to the Cayman Islands. There are several species of ladybeetle that look similar to the spotless ladybeetle. On the Galápagos Islands, it lives in sympatry with its sister species, Cycloneda galapagensis.
Cycloneda sanguinea is a large ladybird beetle with red, unspotted elytra (wing covers) ranging from 4-6.5 mm long. The color ranges from orange to deep red. The white and black marks on the head and pronotum are very distinctive, and are gender-specific. Females and males both have white spots on the black part, but the female has black in the center, continuing down into the face, while the male has a white cleft above the head and a white face. These ladybugs are often found feeding on aphids on milkweeds, but also occur on a number of other plants.
Their eggs are typically orange or yellow, and around 1 mm in diameter. The larvae are larger... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Spotless Lady Beetle is recorded against all the insects logged in Houston (265 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.
