Help! First it was the invasion of the Asian Beetles that look like
ladybugs, now we're being overwhelmed with a new bug and I could use some
help identifying it.
It is black, has 6 legs and is a half-inch long. Body width of
It has two antennae, which are almost as long as its body.
It can fly, but it mostly walks on the windows in sunny locations.
When the wings open, they are bright orange, almost the same color as
ladybugs. When they are closed, they form a /\\ on the top of the bug body.
It's like an orange detail stripe.
They began appearing after our first freeze and just like the Asian beetles,
are trying to make their way indoors. There are hundreds of them all over
our windows and doors, in sunny locations, and of course every time you open
the door, some make there way in.
I'm in Wisconsin and have never seen these before. Any ideas?
I imagine one of your neighbors has a box elder. I don't have any on my
property either, but I found a large swarm of the bugs on the front of my
garage last weekend. Presumably there's a box elder somewhere in my
neighborhood. Or perhaps they infest other species of trees as well?

The Boxelder tree is a member of the Maple family so any maple can
serve as food for these guys....
They're as bad as ladybugs at this time of year.
I also get inundated with Western Conifer Seed bugs here in N.
Illinois. I call them the evil threesome, ladybugs, boxelder bugs, and
WCSB. Between the three of them, life is pretty bad at my house...

As mentioned they are box elder bugs, which can be found on about 5
different type of trees. Only sure solution is tree removal. Timely
tree spraying in the Spring can help the problem in the Fall depending
on how big the tree is. Fall spraying of the structure can reduce the
numbers that can get in short term...the numbers already in the wall
can't be taken care of. Just a nuisance bug that can create an odor
when many are in the walls or will stain light colored curtains and
