The Multicolored Asian Lady Beetle

The Multicolored Asian Lady Beetle, Harmonia axyridis, was introduced into the US by the USDA in 1978 as aphid biocontrol. In several states, it has become a nuisance species due to its habit to seek shelter in homes or buildings from the fall season to early spring. Their defensive secretions stain walls and produce a foul smell. This chemical may cause extreme allergic reactions in some people. Their numbers can reach the tens of thousands in a single home! Luckily, this bug has never been abundant in El Paso.
The number of spots may vary (0-19)
