Tangelone citrus tree curled leaves
can you please look at the linked pictures and tell me what my still young Tangelone Tree has?
What I saw and did:
A few days ago I started seeing some little single eggs sticking on ONLY new leaves. With some help we figured out that it's kind of a caterpillar egg. I sprayed the tree with BT (one time so far) and it looks like it's under control.
I see some spider webs but can't see mites (i also looked at the underside of the leaves but didn't see anything). One time I have seen a spider crawling around as big as my small fingernail.
I can also see some ants crawling on the leaves but just a few.
New leaves look good but just today I saw them starting to curl too.
Thanks for your help!!!
