Please help me help my kumquats!

[cpatte2]

I am new to this citrus thing so please bear with me and help if you can...
A little over a year ago I bought a kumquat tree. It did fair, grew some leaves had a few fruits, nothing grand. Well a few months ago it got ill, drop all leaves then grew back deformed leaves, then dropped leaves and began dying from the top down branch by branch. I cut off all the dead wood, repotted in new soil, and will wait and see. Never saw any bugs until today. (Another dead stem too.) Today I found these little ant sized catipillar looking bugs. See pic, I hope they post....Any thoughts?

Okay... the story continues. Last week I figured I would have a go at 2 new kumquat trees, a meiwa and a nagami. Potted as recommended at the nursery... Then today I find some funky looking leaves on the meiwa and the underside of some leaves on the nagami. The leaves are sort of curled with what looks like a waxy coating on them. Also the color of the leaves on both are a bit yellowish. Please offer any thoughts. Again, I hope my picutes post ok. Thank you, thank you if you have any thoughts. I have tried to research but not much luck.

I am not sure about the first tree but as for the others, the yellow on the leaves is probably a nutrient deficiancy(if there is green viens on the yellow leaves it is most likely iron deficiancy there are iron chelates that you spray on the leaves to help with with iron deficiancy, I am not sure of any organic ways to help deficiancies). If it doesn't have viens then it is probably still a defic. but I am not sure what kind you can do a google such for plant defic. For you funky cut of leaves I think it might be scale I am not sure exactly how to treat. As for the Nagami underside it looks like Citrus leaf minor and certain oils can help with this problem. Now I am going to advise this website to you because it deals with mostly all citrus and the people there with answer the questions I could not answer

Here is the site: www.citrus.forumup.org

thanks so much for the reply peachguy. I actually posted this message on the citrus forum too! I have had one reply and they thought the nagami had leaf miner also. so now I am off to google leaf miner, scale, and plant nutrition. At least now I have some terms to search. thanks.
