Is this a facetotecta nauplius?

This larva was captured using a plankton net in the Persian Gulf during the summer. I believe it may be a Facetotecta nauplius.

I think it is a leaf tip tendril

The leaf seems to be of Citrus sp. If yes, these are compound leaflets and the tips are the modified leaflet.

I dont have an answer,...I am searching for one.

It is definitely a Pecan leaf.

Thanks

Mainly on one shoot and cluster of leaves on that shoot.

Only on some trees.

It is not a significant "problem"/manifestation,...but we saw it last season on some trees and now in this season again.

We thought it is maybe a nutritional disorder, but at this stage I doubt it.

No, we did not.

Well someone directed me to investigate "galls" as a result of wasps.

My colleagues reported the phenomena at three different localities, 200 km from each other approx. I think there is more to it than just coincidence.
