About the Spotless Lady Beetle

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 →
