Asian Lady Beetle

I found these creepy little bugs in various states of growth on a rosebush near my front door. I first noticed them when I saw brown spots on a nearby plant. A quick Google search showed me that they are Asian lady beetle larvae. This invasive species has pushed out the native ladybugs throughout North America.

There are two stages of growth. The fuzzy one is a larval stage and the smoother one is a pupa. I saw lots of beetles too, but I couldn't manage to get a picture. They are very round and red at first, but turn orange or yellow with lots of spots.

I killed every one I found and trimmed the rose bush back almost entirely, to remove anything that looked damaged or diseased. There was also this sticky residue with black specks all over. I suspect this is leftovers from the larvae sacks after the metamorphosis into a beetle.
