Taken in September in Connecticut. I’ve read that the “M” marking rule is not perfect, nor color/symmetry. Mainly wanna know if they are invasive or not. They aren’t pests (for now), just was on our porch.

    You sound more informed than me, but that’s about where I’m at too lol. I couldn’t see where that infographic originally came from, but I’ve spent the day reading the Wikipedia articles on these guys. Supposedly, lady beetles from all over were introduced to kill aphid populations, to varying degrees of success. It ended up harming native populations more, ofc. I guess by being better at eating prey? (Skill issue?)
