I mentioned the aphids on the Asclepias curassavica (scarlet milkweed) when I posted the photo of the large milkweed bug a few days ago. Here’s a picture of the aphids. It was fairly dark when I took this (7:45 in the evening) and I used a flash to light them, which allowed me to get reasonable depth of field. I used a flashlight give me enough light to focus, with the camera on a tripod (which I definitely should use more often). As I was taking the pictures, I realized the aphids were not alone. There is a larva of a lady beetle of some sort (probably an Asian lady beetle, Harmonia axyridis), feeding on the aphids. Unfortunately, there are too many aphids for this lone predator, and I’m going to need to take care of them myself.

It was a beautiful, if somewhat hot afternoon today and I went out into the woods next to my building. As I walked through the underbrush under the sycamore, tulip poplar, redbud, walnut, and black cherry trees, I noticed this little creature on a leaf. This is the larva of a lady beetle. The family Coccinellidae, the lady beetles, has about 6,000 species in 360 genera worldwide and nearly 500 in eastern North America. I have no idea to which of those this larva belongs and I’m not even going to try to figure it out. The adults are generally easier to narrow down but to me, anyway, the larva are just too much alike. I found a key to the larva of North American lady beetles but it starts out as follows. Tell me how helpful this is to you:
Mandible with digitiform teeth, retinaculum absent; terga with scoli, sometimes with parascoli; frontoclypeal suture complete; antenna long, 3 or more times as long as wide, of nearly uniform diameter.
