Beetles, aphids and lacewings - oh my!

Yesterday I was sitting in my deck enjoying a nice evening. I noticed a few aphids landed on one of my dogs! Of course I got excited seeing the first winged aphid of the season (I know that only a few people in the world get a thrill from seeing aphids!). I have no idea what the species was, but I know it WASN'T soybean aphid. So I used my phone camera to take a few pics of the aphid and a few other insects flying around the yard. I noticed a multicolored Asian lady beetle, a few brown lacewings and a ton of flies. I did think it was interesting two of these insects are considered predatory as larvae and adults. I wonder if they were finding enough food?
