Mango sap sucking insects

[Kumar]

I have in this topic photographed a sap sucking insect that seems to have a liking for mango.

This is one of my mango trees, about 18 years old. It is quite robust and has a nice crown though growth has slowed down considerably in the last two years. (Small metal hacker for scale)

On close examination, one can see the slight unnatural bumps on the bark, wonderfully camoflauged

These bumps are evidently cells of some sort and are stuck onto the bark by a strong adhesive. The trick is to scrape them off without hurting the bark. Here, the two cells are visible, fallen onto the ground

And finally here is the notorious yellow maggot (perhaps it gets the colour from all that mango sap), exposed by gently rocking the cell. On its own it is immobile and poses no threat. Perhaps someone can identify it?
