Multicolored Asian Lady Beetle

The multicolored Asian lady beetle (MALB), Harmonia axyridis, is a predatory lady beetle native to eastern Asia that was first detected in Minnesota in 1994. It has become an economically significant contaminant pest in the wine-making process in the eastern and Midwestern United States. In the vineyard, grape clusters that have been injured due to physiological splitting, yellowjackets, or birds are an attractive option for MALB.
