For weeks now, the insects currently clustering in homes here in the North East, are tiny Fall visitors called Asian lady beetles. These little uninvited guests, ranging in color from red to orange and yellow with black and white markings, are swarming to homes in preparation for the Winter conditions to come. Both our native red ladybugs and Asian lady beetles are in the insect family Coccinellidae, and although they can look alike, they have very distinct behaviors. The easiest way to tell them apart is to look for a distinctive white “M” on the beetles’ heads.

Lady beetles may appear cute to the human eye, but in the insect world, they are fearsome predators.

They get under the edges of my windows, and I find them when I release one of my banded birds out the window.
