These beetles were introduced in the U.S. by the Department of Agriculture, supposedly because they have a larger appetite for aphids than our native lady beetles. They can be yellow, orange or red, and have anywhere from zero to nineteen spots. When disturbed, they are capable of reflex bleeding from their joints, and an unpleasant smell.
Native species are dwindling as this species' population is growing dramatically.
These will eat any soft-bodied insect. I've seen an adult eat a pupa of the same species here.

This species is most common in fall. They build up their numbers during the growing season, spring being their lowest number since in Minnesota they may suffer massive morality rates. They will enter houses and pile up in a hiburation state, staining cloths and rugs. They are the only species of ladybug in Minnesota that actively seek out heat like the Box elder bugs. They are common around large building, gathering around doors and walls seeking the heat of the sun. Will bites - feel like a tiny pinch. Even when they lands on people and they are not disturbed they will explore bite to see if we are edible to them! They may have wiped out large numbers of native ladybug species in Minnesota (not proved yet) and no study so far have record the native ladybug species that are left. A species, two spotted ladybug which are quite distinct with two large black spots on a red background like what books, tv, etc use to portray the ideal ladybug used to be common around when I was young but now are rare. Asiatic ladybug can also be mistook for other species of ladybugs since their colors can vary from pale orange - yellow to dark orange- red and their spots vary, with sixteen being their maximum and four the fewest. A source on the internet even said they can be mostly black with four tiny red spots near their head!

These things are the worst ever introduced! The negative mark I gave is to to nice for this one. These little beetles get everywhere around the house. Have tried to seal up the house as best as I can and still they find ways to get in. I lay in bet try to sleep and they dive bomb and bite. One afternoon I pulled up my driveway and when I got to my garage that is normally white it was a blackish-orange with so many of these little things on the exterior soaking up the heat of the sun. That was a couple years ago, they have got less in numbers but I wonder if they have a population cycle.
Also if you try to kill them and scwoosh them they stink and that attract more.
Nasty little things!

I'll add my negative to this.

One, they are not native. Two, they try to hibernate in mass numbers in my home. It was creepy seeing my front window covered with these. It was the one and only time we hired an exterminator. If we get these again, we'll use non-chemical means. Three, they bite. Four, when the aphid numbers drop, they will take tiny bites out of peaches, nectarines, apricots. Was I miffed when I found that out! When I first saw them on the fruits, I thought they were eating pests.

About their smell... I've smelled worse, so that doesn't bother me. :) I will squish them with my bare hands if I have nothing else.
