What is black.ladybug?

I am sorry, but as an AI language model, I do not have any particular information about a black ladybug. Ladybugs or ladybirds are insects that belong to the Coccinellidae family. They are commonly found all over the world and are often considered as beneficial insects because they feed on plant pests. Ladybugs come in different colors and patterns, but the most common and recognizable type is the red or orange ladybug with black spots. However, there are also ladybugs with black shells or spots, but I cannot confirm if they are exclusively referred to as "black ladybugs."
