You have several different bugs that I'm not qualified to identify. However, I occasionally get the same problem on many of my Hibiscus. The remedy is a mixture of two tablespoons of powdered garlic and half a cup of dish detergent (I use Dawn, but there's some talk of it being too strong, but it works for me) in a gallon of water. If they're not in bloom now, cut them back before you spray. Drench the leaves, spray the buds, and make sure you get the underside of everything. Repeat weekly for a few weeks.

Thanks! I didn't think they looked the same. The buds I shown above are about all there is at the moment, so this would be a good time to spray. Adding garlic is a new one for me, but it makes sense. Thanks again!

Here's some help.

Thank you! That is very helpful.

This has been a bad year for pests for us. I've had scale, mealies and aphids more than ever! I want to blame my next door neighbor - he's seasonal (Germany) and won't let anyone spray anything, even organic and bee safe sprays. Weeds and pests are wild over there. He's the guy who even planted dandelions. He tried to tell me they can be eaten. I told him I was from Appalachia and I know you can eat them and make wine, but we don't grow it as a crop! Oh well, I'm probably being unfair.

I do practice safe spraying. We are on a bee migration flight path.

1st & 2nd looks like aphids - some parasitized by a wasp, others dead husks after something fed on them - possibly ladybug or lacewing larvae. 3rd looks like mealybugs to me.
