It's my Lady Beetle Anniversary! (Coccinelliversary?)

One year ago today I was looking for caterpillars and found a lady beetle larva instead - a big, orange and black, fourth-instar Multicolored Asian Lady Beetle (Harmonia axyridis). I'd seen and identified one the previous year, so I recognized it for what it was, but didn't remember the name. That's the last time I was unable to put a name to an H. axyridis larva...now I am one of the experts on the larval development of the species! I took that first larva to my office, along with a plant stem covered with aphids, and watched the little beast munch its way through the aphids all day. I released it in the place where I found it after work, because I wasn't sure I could take it home and raise it like I always did with caterpillars. Finding and collecting enough aphids seemed like a challenge that I couldn't meet yet. But just a few days later, I found lady beetle eggs, took them home, and when they hatched I was able to rear them with aphids from my backyard and various sidewalk weeds. I've been a lady bug nut ever since, especially for the larvae. I've even been consulted by the Lost Ladybug Project at Cornell University! And all because, a year ago today, I found that little orange and black creature I wasn't even looking for. I'm not especially superstitious, but I have to say, I do believe that ladybug was lucky!
