I was looking at one of my roses yesterday and it was covered with little (teeny) yellow bugs. It hasn't spread to any of my other roses. Any thoughts on what it might be?
Could you describe them a little more? Are they winged or wingless? Do they jump when disturbed? Are they on the underside of the leaves or on the flowers? How big are they (etc.)? The first link below has some excellent images (unfortunately, no close ups of aphids) and the second link is from Cornell and is well worth the read. Hope this helps.
Thank you for your reply. I think they are aphids. I've been looking at other information on this website and the descriptions fit. They are actually more light green than yellow (maybe the light was playing tricks on my eyes). I've been knocking them off with water and hopefully that will do the trick, although I'm keeping an eye on them.
Oddly enough they are only found on one plant so far.
One way to be sure if they're aphids is to get a magnifying glass and look at the back of the aphid. If, on either side of the end of the abdomen you see a pointy structure (called a cornicle, "exhaust pipe," or "tail pipe"), then you can be sure they're aphids.
I'll check when I get home. If they don't have the pointy thing at the back, what might I be looking at?
I have some yellow bugs with balck legs on my oleander. Do you have any idea what they are? I did knock them off with water, but the tree is about to bloom and I hate to spray it right now. HELP!
