Asian Lady Beetle or Harlequin Ladybird

Harmonia axyridis

Asiatischer Marienkäfer Harmonia axyridisAsian Lady Beetle (so known in North America) or Harlequin Ladybird (so its name in the United Kingdom) is native to eastern Asia, but has been introduced to North America and Europe to control aphid populations. At first almost only in greenhouses this predator has nowadays a worldwide propagation. In autumn Asian Lady Beetle shows a tendency to occur in large swarming and overwinter indoors.

Its coloring is extremely variable, ranging from pale yellow to dark red. Sometimes the mostly 19 black spots are so large that they merge and it seems as if a black beetle would have red dots.
