You are correct those do look like C-mac Ladybugs did not know other types of the lady beetle existed, I know now.
The Ladybug: Coccinellidae
•Has six jointed legs, a pair of antennae, and a three-part body.
•Most gardeners appreciate them as they eat aphids.
•The correct name is lady beetle, but ladybug is the name that is most commonly used.
•There are over 450 species of ladybugs in North America alone.
•There are more than 5,000 different ladybug species in the world.
•Ladybugs are usually red or orange with black markings, but there are some that are black with reddish colored markings and some may have yellow as well.
•They can retract their head into the prothorax like a turtle can.
•Their bodies are always a round or oval dome-shape, and they have hard shell wings that cover their inner wings.
•The four most common types of ladybugs are the round-shaped ladybugs, or the Seven-spotted Ladybug, originally from Europe; the oval-shaped ladybug, known as the Convergent Ladybug; the Multicolored Asian Ladybeetle; and the C-Mac ladybug which is oblong, pink and black spotted.
•The ladybug's life cycle is about 4-6 weeks long.
•Adult ladybugs lay up to 300 eggs among an aphid colony where the eggs will hatch within five days. The newly hatched ladybugs, or larvae, then eat the aphids for up to 3 weeks before entering their pupa stage for another week until they become an adult ladybug. Twenty-four hours later they have developed their spots.
