Two Different Beetles with Similar Names

Two insects with similar-sounding names are present in Iowa. Though they are nothing alike, the names sound enough alike to cause confusion. Here are the two beetles.

Multicolored Asian Lady Beetle: Multicolored Asian lady beetle (or ladybug) is a beneficial predator that eats aphids and other smalll insects during the summer.  It is most noticeable in the fall when the day-lengths shorten and beetles migrate  from trees, gardens and fields to the sunny sides of the building and wandering indoors, becoming an annoying though harmless, household nuisance. MALB is found everywhere in the state.  Please see our website for information on ladybug control in the fall of the year.
