Cross-Breeding????

OK - We have a ton of ladybugs around here. I know, they are Japanese Beetles, but to me they are ladybugs. And I hate them, every last one of them is a thorn in my side. We also are lucky enough to have Box Elder Bugs which are just as fruitful and annoying as the ladybugs. Lately, I have been seeing these bugs pictured below. They are shaped in the front like a ladybug and in the back like a box elder bug. They are a little bigger than a ladybug, but a little smaller than a box elder. I think we have a little cross-breeding going on and we now have box elder beetles. Just what I need--a third little creature to drive me crazy. Might make for a good science experiment for the kids someday. This is nature that I could definately do without.
