Boxelder Bugs

 

I was out of my home territory yesterday, visiting West Deptford, N.J., close to the Delaware River. It was marshy and although I did not see them, I know there were lots of boxelder trees nearby. I know because I saw their namesake insect -- the boxelder bug. Behold, above. This was more of an event than it sounds, because I'd never seen one before. As if to make up for lost time, I saw thousands of them yesterday. Click to enlarge.

I saw them on cars and walls, a lot of them, clustering especially on white backgrounds. They were sitting in the sunshine, seeking warmth. It's their yearly autumn swarm, during which they look for warm places to overwinter. They'll try to get inside buildings, but will settle for any sheltered nook. After spending the winter dormant, they'll again emerge in spring. I'd never seen them because there were no boxelder trees in my neighborhood; they eat mainly the leaves flowers and seeds of boxelders and do not stray far from them.
