These look like aphids, but they are the color of mustard. Every year these show up on the very new growth of the Hosta (here in photo) and this year a few are showing up on the really new growth of the Mandevilla. I've never seen them on other plants. They seem only to be on the newest growth and never hiding down in the foliage. They are easy to wipe off with my fingers. I've never seen any with wings or any other stage of growth. Even though they look to be a sucking organism, there is no detectable damage to the growth on either the Hosta or the Mandevilla. Anyone else have experience with them and know what they are?
