Today I decided to photograph the interesting flowers of my Bryophyllum pinnatum (Kalanchoe pinnatum). Upon looking at the photo immediately after taking the picture I discovered that the plant was infested with aphid insects. This is a benefit of digital cameras, you can immediately see the picture. This plant was in a south-facing (brightly lit) window behind other plants so that I could not easily get close enough to discover the insects. The camera proved extremely useful.
