I tried to get close enough. It looked like a big fly with white wings, but had like big eyes and was about an inch long. Black mainly but with white wings.

Mikes the bug is a wolly mealy bug. The plant is in a pot I assume.......maybe post in on the citrus forum as there are a lot of people there that grow in pots. I have 15 citrus in the ground and have never seen leaves do that so I would just be guessing at the cause. Here is a link that might be useful: Citrus forum

I would still go with the diatomaceous earth...it can do in a number of pests. Put it around your containers, around the plants and dust the plants with it. You could also find a fabric store(or a Walmart with a fabric dept) and purchase some fine Tulle netting(it's very cheap), then drape it over your plants(using sticks or stiff wire for support), securing it around the rim of your pots. Another option is an insecticidal soap(I use Safer's). HTH

Had some fruit flies a few weeks ago, when I bought 20 pounds of grapes for this year's jelly. I found that using apple cider (real cider, not cider vinegar) in the homemade trap (bowl, covered with saran, poked with a toothpick) attracted them like crazy. One caution about the weevils that arrive in your grain products. DO NOT count on plastic containers (like Tupperware, gladware, rubbermaid) to keep them from spreading. They're tiny enough that they can often crawl right through the seal. Better to use something like a ziplock bag. All grain products you buy have the eggs, so the trick is to not let them hatch. That means: buy from stores that have a quick turnover, that properly store products; keep your grain products in a cool environment (even freezing) to slow down the hatching process. And, of course, when you do occasionally find a few pets in your kitchen cabinet, get rid of the product, clean well, and put new products in ziplock bags. Of course, the good news is that weevils won't hurt you if you eat them--not that you want to, but they aren't dangerous to your health. You can, in a pinch, sift your flour, cake mixes, through a fine strainer to remove the live ones. With rice or pasta, they'll usually rise to the top of the cooking water and can be easily scooped out at that point--the food is certainly safe to eat.
