As an expert in entomology, I can tell you that the term "poison ladybug" is not a scientifically recognized term for any specific species of ladybug. However, it's possible that you might be referring to ladybugs that are harmful or have a strong odor when disturbed, such as the Asian lady beetle (Harmonia axyridis) or the Mexican bean beetle (Epicauta pennsylvanica).

Asian lady beetles can vary in color from orange to yellow and may have anywhere from 0 to 20 black spots on their elytra (wing covers). The Mexican bean beetle is typically yellow with 15 black spots on the elytra.
