Ill-fated numerous introductions by people and organizations keen on aphid and other "pest" control brought this thing to us. Now, MALB's are ubiquitous and overly abundant. This is the lady beetle that swarms houses in late fall and piles into attics, crevices and other protected niches, much to the consternation of the homeowner.
I was in Adams County yesterday, and made the four mile round trip to the iconic Buzzard's Roost Rock, which is in the heart of the Edge of Appalachia Preserve. Even though this is, by Ohio standards, a largely wild and invasive-free landscape, it was shocking how many of these lady beetle larvae were there. A scan of small trees and shrubs would often yield a dozen or more lady beetle larvae.
One would hope that humans would learn the folly of introducing nonnative animals, but I have no great hopes that we will ever learn our lesson and quit tampering with "biological control".
