The white bumps on the thorax of the lacewing larva mark the masses of internal tissue that will later form the adult wings. They are called imaginal discs. There are other groups of tissues in the larva that will replace other parts of the larva, and maybe these are located at the other white markings. A large % of an insect larva is pretty much disintegrated during metamorphosis, to be replaced by these other tissues. Strange things, insects.
Thanks for the info. Never noticed those before. Lacewing larva are often covered in dirt, pollen, sometimes empty prey bodies, making them hard to see against it's background, and obscuring anatomy.
