Foam nests, update

Quite a few posts back I showed some unidentified foam nests placed on the leaves of a clump of lemon grass. At first I thought they might be the work of tree frogs, but as it turned out, they were insects. What insect, I can't say, but one day I collected some of the foam and found this insect inside. When I first separated it from the foam, it seemed to be in a larva state. A few minutes later it got cleaned up and this is the result. Eventually it took off on its own accord but I don't know if it walked away or used wings. Our friend is composing itself on a rolled up lemon grass leaf.
