BROWN MARMORATED STINK BUG Halyomorpha halys
P.S. I've added this 100% crop to show the red eye spots. Please click on the photo to see an enlargement. You can also plainly see the separate lenses of the compound eye.
Last year we had a few of these stinkbugs emerge at various times throughout the winter from their hiding places in our home but this year they are much more in evidence. I think I counted 6 bugs total last year and we've already have seen that number this year before they really get active when the warm weather arrives. Shows how air tight our home is if they can manage to squeeze through tiny cracks and somehow end up in the house. The adult bug is about the size of a dime. They are somewhat more persistent than lady bugs. I usually see a couple of the ladybug carcasses in the house usually along the windowsills but I haven't seen any this year.
Here's a good site for more information about the stinkbug which seems to becoming well established and increasing in numbers if the amount found in our house is any indication.
This bug is smaller than most and appears to be dying. Maybe the small size makes it more vulnerable to dessication. I don't know how the stinkbug survives indoors in a rather dry centrally heated environment. During this time it doesn't eat or drink yet some of them are still alive when spring arrives.
I took the photo with my homemade macro attachment consisting of two binocular objective lens elements. I used the camera flash which was too harsh until I covered it with an index card. I was surprised to see the two red false eyes? I couldn't see them with my naked eyes. Click on the photo to see an enlargement. It's difficult to see the red eyes in the small photo which seems to be about an 8x enlargement.
