Sounds almost biblical but it’s only another insect post. I spotted this little bit of fluff on an elderberry leaf in our yard and, at first, thought it a wooly aphid. But with some research on the larger image realized it was a Citrus Flatid Planthopper nymph-Metcalfa pruinosa. I’ve never photographed that aphid so was a little disappointed but this is a cute little bugger so am happy with the image. Look at that eye and the cottony tail end.
Of course, as it is nymph season there isn’t an adult around to photograph so here is a shot from a few years ago of an adult.
These are relatively harmless and are not host specific although, as the name implies, do favor citrus trees. In some locations they can cause problems with citrus crops but don’t represent a plague. I am not sure what in my yard attracts them specifically but we have none of their namesakes.
